-	  pmake on IRIX can be invoked from the root directory, but the

-	  Currently, not all MPI-IO packages support the complicated
-	  MPI derived datatypes used in the implementation of irregular
-	  selections INSIDE HDF5.

-	     please edit powerpc-ibm-aix5.x in the directory hdf5/config/.
-	     Find the line with

-	     and UNCOMMENT this line before the configure.
-	     check poe version with the following command:
-	     lpp -l all | grep ppe.poe
-	  3) For Linux cluster,:
-	     If mpich version is 1.2.5 or lower, collective irregular selection
-	     IO is not supported; internally independent IO is used.

+                If the mpich version is 1.2.5 or lower, please find the
+                corresponding config (in hdf5/config) file and add
+                    hdf5_mpi_complex_derived_datatype_works='no'
+                at the end of the configuration file. For example, on the

+                    hdf5_mpi_complex_derived_datatype_works='no'
+                should be added at the end of the config file ia64-linux-gnu.

+New Features
+============
+
+    Configuration:
+    -------------
+    - Disable memory sanity checks in the Autotools in release branches
+
+      The library can be configured to use internal memory sanity checking,
+      which replaces C API calls like malloc(3) and free(3) with our own calls
+      which add things like heap canaries. These canaries can cause problems
+      when external filter plugins reallocate canary-marked buffers.
+
+      For this reason, the default will be to not use the memory allocation
+      sanity check feature in release branches (e.g., hdf5_1_10_7).
+      Debug builds in development branches (e.g., develop, hdf5_1_10) will
+      still use them by default.
+
+      This change only affects Autotools debug builds. Non-debug autotools
+      builds and all CMake builds do not enable this feature by default.
+
+      (DER - 2020/08/19)
+
+    - Add file locking configure and CMake options
+
+      HDF5 1.10.0 introduced a file locking scheme, primarily to help
+      enforce SWMR setup. Formerly, the only user-level control of the scheme
+      was via the HDF5_USE_FILE_LOCKING environment variable.
+
+      This change introduces configure-time options that control whether
+      or not file locking will be used and whether or not the library
+      ignores errors when locking has been disabled on the file system
+      (useful on some HPC Lustre installations).
+
+      In both the Autotools and CMake, the settings have the effect of changing
+      the default property list settings (see the H5Pset/get_file_locking()
+      entry, below).
+
+      The yes/no/best-effort file locking configure setting has also been
+      added to the libhdf5.settings file.
+
+      Autotools:
+
+        An --enable-file-locking=(yes|no|best-effort) option has been added.
+
+        yes:          Use file locking.
+        no:           Do not use file locking.
+        best-effort:  Use file locking and ignore "disabled" errors.
+
+      CMake:
+
+        Two self-explanatory options have been added:
+
+        HDF5_USE_FILE_LOCKING
+        HDF5_IGNORE_DISABLED_FILE_LOCKS
+
+        Setting both of these to ON is the equivalent to the Autotools'
+        best-effort setting.
+
+      NOTE:
+      The precedence order of the various file locking control mechanisms is:
+
+        1) HDF5_USE_FILE_LOCKING environment variable (highest)
+
+        2) H5Pset_file_locking()
+
+        3) configure/CMake options (which set the property list defaults)
+
+        4) library defaults (currently best-effort)
+
+      (DER - 2020/07/30, HDFFV-11092)
+
+    - CMake option to link the generated Fortran MOD files into the include
+      directory.
+
+      The Fortran generation of MOD files by a Fortran compile can produce
+      different binary files between SHARED and STATIC compiles with different
+      compilers and/or different platforms. Note that it has been found that
+      different versions of Fortran compilers will produce incompatible MOD
+      files. Currently, CMake will locate these MOD files in subfolders of
+      the include directory and add that path to the Fortran library target
+      in the CMake config file, which can be used by the CMake find library
+      process. For other build systems using the binary from a CMake install,
+      a new CMake configuration can be used to copy the pre-chosen version
+      of the Fortran MOD files into the install include directory.
+
+      The default will depend on the configuration of
+      BUILD_STATIC_LIBS and BUILD_SHARED_LIBS:
+            YES                   YES         Default to SHARED
+            YES                   NO          Default to STATIC
+            NO                    YES         Default to SHARED
+            NO                    NO          Default to SHARED
+      The defaults can be overriden by setting the config option
+         HDF5_INSTALL_MOD_FORTRAN to one of NO, SHARED, or STATIC
+
+      (ADB - 2020/07/09, HDFFV-11116)
+
+    - CMake option to use AEC (open source SZip) library instead of SZip
+
+      The open source AEC library is a replacement library for SZip. In
+      order to use it for hdf5, the libaec CMake source was changed to add
+      "-fPIC" and exclude test files. A new option USE_LIBAEC is required
+      to compensate for the different files produced by AEC build.
+
+      Autotools does not build the compression libraries within hdf5 builds,
+      but will use an installed libaec when configured as before with the
+      option --with-libsz=<path to libaec directory>.
+
+      (ADB - 2020/04/22, OESS-65)
+
+    - CMake ConfigureChecks.cmake file now uses CHECK_STRUCT_HAS_MEMBER
+
+      Some handcrafted tests in HDFTests.c have been removed and the CMake
+      CHECK_STRUCT_HAS_MEMBER module has been used.
+
+      (ADB - 2020/03/24, TRILAB-24)
+
+    - Both build systems use same set of warnings flags
+
+      GNU C, C++ and gfortran warnings flags were moved to files in a config
+      sub-folder named gnu-warnings. Flags that only are available for a specific
+      version of the compiler are in files named with that version.
+      Clang C warnings flags were moved to files in a config sub-folder
+      named clang-warnings.
+      Intel C, Fortran warnings flags were moved to files in a config sub-folder
+      named intel-warnings.
+
+      There are flags in named "error-xxx" files with warnings that may
+      be promoted to errors. Some source files may still need fixes.
+
+      There are also pairs of files named "developer-xxx" and "no-developer-xxx"
+      that are chosen by the CMake option:HDF5_ENABLE_DEV_WARNINGS or the
+      configure option:--enable-developer-warnings.
+
+      In addition, CMake no longer applies these warnings for examples.
+
+      (ADB - 2020/03/24, TRILAB-192)
+
+    - Update CMake minimum version to 3.12
+
+      Updated CMake minimum version to 3.12 and added version checks
+      for Windows features.
+
+      (ADB - 2020/02/05, TRILABS-142)
+
+    - Fixed CMake include properties for Fortran libraries
+
+      Corrected the library properties for Fortran to use the
+      correct path for the Fortran module files.
+
+      (ADB - 2020/02/04, HDFFV-11012)
+
+    - Added common warnings files for gnu and intel
+
+      Added warnings files to use one common set of flags
+      during configure for both autotools and CMake build
+      systems. The initial implementation only affects a
+      general set of flags for gnu and intel compilers.
+
+      (ADB - 2020/01/17)
+
+    - Added new options to CMake for control of testing
+
+      Added CMake options (default ON);
+          HDF5_TEST_SERIAL AND/OR HDF5_TEST_PARALLEL
+          combined with:
+            HDF5_TEST_TOOLS
+            HDF5_TEST_EXAMPLES
+            HDF5_TEST_SWMR
+            HDF5_TEST_FORTRAN
+            HDF5_TEST_CPP
+            HDF5_TEST_JAVA
+
+      (ADB - 2020/01/15, HDFFV-11001)
+
+    - Added Clang sanitizers to CMake for analyzer support if compiler is clang.
+
+      Added CMake code and files to execute the Clang sanitizers if
+      HDF5_ENABLE_SANITIZERS is enabled and the USE_SANITIZER option
+      is set to one of the following:
+          Address
+          Memory
+          MemoryWithOrigins
+          Undefined
+          Thread
+          Leak
+          'Address;Undefined'
+
+      (ADB - 2019/12/12, TRILAB-135)
+
+
+    Library:
+    --------
+    - Add metadata cache optimization to reduce skip list usage
+
+      On file flush or close, the metadata cache attempts to write out
+      all dirty entries in increasing address order.  To do this, it needs
+      an address sorted list of metadata entries.  Further, since flushing
+      one metadata cache entry can dirty another, this list must support
+      efficient insertion and deletion.
+
+      The metadata cache uses a skip list of all dirty entries for this
+      purpose.  Before this release, this skip list was maintained at all
+      times.  However, since profiling indicates that this imposes a
+      significant cost, we now construct and maintain the skip list only
+      when needed.  Specifically, we enable the skip list and load it with
+      a list of all dirty entries in the metadata cache just before a flush,
+      and disable it after the flush.
+
+      (JRM - 2020/08/17, HDFFV-11034)
+
+    - Add BEST_EFFORT value to HDF5_USE_FILE_LOCKING environment variable
+
+      This change adds a BEST_EFFORT to the TRUE/FALSE, 1/0 settings that
+      were previously accepted. This option turns on file locking but
+      ignores locking errors when the library detects that file locking
+      has been disabled on a file system (useful on some HPC Lustre
+      installations).
+
+      The capitalization of BEST_EFFORT is mandatory.
+
+      See the configure option discussion for HDFFV-11092 (above) for more
+      information on the file locking feature and how it's controlled.
+
+      (DER - 2020/07/30, HDFFV-11092)
+
+
+    - Add H5Pset/get_file_locking() API calls
+
+      This change adds new API calls which can be used to set or get the
+      file locking parameters. The single API call sets both the "use file
+      locking" flag and the "ignore disabled file locking" flag.
+
+      When opening a file multiple times without closing, the file MUST be
+      opened with the same file locking settings. Opening a file with different
+      file locking settings will fail (this is similar to the behavior of
+      H5Pset_fclose_degree()).
+
+      See the configure option discussion for HDFFV-11092 (above) for more
+      information on the file locking feature and how it's controlled.
+
+      (DER - 2020/07/30, HDFFV-11092)
+
+    - Add Mirror VFD
+
+      Use TCP/IP sockets to perform write-only (W/O) file I/O on a remote
+      machine. Must be used in conjunction with the Splitter VFD.
+
+      (JOS - 2020/03/13, TBD)
+
+    - Add Splitter VFD
+
+      Maintain separate R/W and W/O channels for "concurrent" file writes
+      to two files using a single HDF5 file handle.
+
+      (JOS - 2020/03/13, TBD)
+
+    - Fixed an assertion failure in the parallel library when collectively
+      filling chunks. As it is required that chunks be written in
+      monotonically non-decreasing order of offset in the file, this assertion
+      was being triggered when the list of chunk file space allocations being
+      passed to the collective chunk filling routine was not sorted according
+      to this particular requirement.
+
+      The addition of a sort of the out of order chunks trades a bit of
+      performance for the elimination of this assertion and of any complaints
+      from MPI implementations about the file offsets used being out of order.
+
+      (JTH - 2019/10/07)
+
+    Fortran Library:
+    ----------------
+    - Add wrappers for H5Pset/get_file_locking() API calls
+
+      h5pget_file_locking_f()
+      h5pset_file_locking_f()
+
+      See the configure option discussion for HDFFV-11092 (above) for more
+      information on the file locking feature and how it's controlled.
+
+      (DER - 2020/07/30, HDFFV-11092)
+
+    - Added new Fortran parameters:
+
+        H5F_LIBVER_ERROR_F
+        H5F_LIBVER_NBOUNDS_F
+        H5F_LIBVER_V18_F
+        H5F_LIBVER_V110_F
+
+    - Added new Fortran API: h5pget_libver_bounds_f
+
+      (MSB - 2020/02/11, HDFFV-11018)
+
+    C++ Library:
+    ------------

+
+      See the configure option discussion for HDFFV-11092 (above) for more

+    - h5repack added options to control how external links are handled.
+
+      Currently h5repack preserves external links and cannot copy and merge
+      data from the external files. Two options, merge and prune, were added to
+      control how to merge data from an external link into the resulting file.
+       --merge             Follow external soft link recursively and merge data.
+       --prune             Do not follow external soft links and remove link.

+Bug Fixes since HDF5-1.10.6 release
+==================================
+
+    Library
+    -------
+    - Fix bug and simplify collective metadata write operation when some ranks
+        have no entries to contribute.  This fixes parallel regression test
+        failures with IBM SpectrumScale MPI on the Summit system at ORNL.
+
+      (QAK - 2020/09/02)
+
+    - Avoid setting up complex MPI types with 0-length vectors, which some
+        MPI implementations don't handle well.  (In particular, IBM
+        SpectrumScale MPI on the Summit system at ORNL)
+
+      (QAK - 2020/08/21)
+
+    - Fixed use-of-uninitialized-value error
+
+      Appropriate initialization of local structs was added to remove the
+      use-of-uninitialized-value errors reported by MemorySanitizer.
+
+      (BMR - 2020/8/13, HDFFV-11101)
+
+    - Creation of dataset with optional filter
+
+      When the combination of type, space, etc doesn't work for filter
+      and the filter is optional, it was supposed to be skipped but it was
+      not skipped and the creation failed.
+
+      A fix is applied to allow the creation of a dataset in such
+      situation, as specified in the user documentation.
+
+      (BMR - 2020/8/13, HDFFV-10933)
+
+    - Explicitly declared dlopen to use RTLD_LOCAL
+
+      dlopen documentation states that if neither RTLD_GLOBAL nor
+      RTLD_LOCAL are specified, then the default behavior is unspecified.
+      The default on linux is usually RTLD_LOCAL while macos will default
+      to RTLD_GLOBAL.
+
+      (ADB - 2020/08/12, HDFFV-11127)
+
+    - Fixed issues CVE-2018-13870 and CVE-2018-13869
+
+      When a buffer overflow occurred because a name length was corrupted
+      and became very large, h5dump crashed on memory access violation.
+
+      A check for reading past the end of the buffer was added to multiple
+      locations to prevent the crashes and h5dump now simply fails with an
+      error message when this error condition occurs.
+
+      (BMR - 2020/7/31, HDFFV-11120 and HDFFV-11121)
+
+    - H5Sset_extent_none() sets the dataspace class to H5S_NO_CLASS which
+      causes asserts/errors when passed to other dataspace API calls.
+
+      H5S_NO_CLASS is an internal class value that should not have been
+      exposed via a public API call.
+
+      In debug builds of the library, this can cause asserts to trip. In
+      non-debug builds, it will produce normal library errors.
+
+      The new library behavior is for H5Sset_extent_none() to convert
+      the dataspace into one of type H5S_NULL, which is better handled
+      by the library and easier for developers to reason about.
+
+      (DER - 2020/07/27, HDFFV-11027)
+
+    - Fixed the segmentation fault when reading attributes with multiple threads
+
+      It was reported that the reading of attributes with variable length string
+      datatype will crash with segmentation fault particularly when the number
+      of threads is high (>16 threads).  The problem was due to the file pointer
+      that was set in the variable length string datatype for the attribute.
+      That file pointer was already closed when the attribute was accessed.
+
+      The problem was fixed by setting the file pointer to the current opened
+      file pointer when the attribute was accessed.  Similar patch up was done
+      before when reading dataset with variable length string datatype.
+
+      (VC - 2020/07/13, HDFFV-11080)
+
+    -  Fixed issue CVE-2018-17438
+
+      A division by zero was discovered in H5D__select_io() of H5Dselect.c.
+        https://security-tracker.debian.org/tracker/CVE-2018-17438
+
+      A check was added to protect against division by zero.  When such
+      situation occurs again, the normal HDF5 error handling will be invoked,
+      instead of segmentation fault.
+
+      (BMR, DER - 2020/07/09, HDFFV-10587)
+
+    - Fixed CVE-2018-17435
+
+      The tool h52gif produced a segfault when the size of an attribute message
+      was corrupted and caused a buffer overflow.
+
+      The problem was fixed by verifying the attribute message's size against the
+      buffer size before accessing the buffer.  h52gif was also fixed to display
+      the failure instead of silently exiting after the segfault was eliminated.

+    - Don't allocate an empty (0-dimensioned) chunked dataset's chunk
+      index, until the dataset's dimensions are increased.
+
+      (QAK - 2020/05/07)
+
+    Configuration
+    -------------
+    - Stopped addition of szip header and include directory path for
+      incompatible libsz
+
+      szlib.h is the same for both 32-bit and 64-bit szip, and the header file
+      and its path were added to the HDF5 binary even though the configure
+      check of a function in libsz later failed and szip compression was not
+      enabled.  The header file and include path are now added only when the
+      libsz function passes the configure check.
+
+      (LRK - 2020/08/17, HDFFV-10830)
+
+    - Added -fsanitize=address autotools configure option for Clang compiler
+
+      Clang sanitizer options were also added for Clang compilers with CMake.
+
+      (LRK, 2020/08/05, HDFFV-10836)
+
+    - Updated testh5cc.sh.in for functions versioned in HDF5 1.10.
+
+      testh5cc.sh previously tested that the correct version of a function
+      versioned in HDF5 1.6 or 1.8 was compiled when one of
+      H5_NO_DEPRECATED_SYMBOLS or H5_USE_16_API_DEFAULT were defined.  This
+      test was extended for additional testing with H5_USE_18_API_DEFAULT.
+
+      (LRK, 2020/06/22, HDFFV-11000)
+
+    - Fixed CMake include properties for Fortran libraries
+
+      Corrected the library properties for Fortran to use the
+      correct path for the Fortran module files.
+
+      (ADB - 2020/02/04, HDFFV-11012)
+
+    Performance
+    -------------
+    - None
+
+    Java Library:
+    ----------------
+    - None
+
+    Fortran
+    --------
+    - Corrected INTERFACE INTENT(IN) to INTENT(OUT) for buf_size in h5fget_file_image_f.
+
+      (MSB - 2020/2/18, HDFFV-11029)
+
+    - Fixed configure issue when building HDF5 with NAG Fortran 7.0.
+
+      HDF5 now accounts for the addition of half-precision floating-point
+      in NAG 7.0 with a KIND=16.
+
+      (MSB - 2020/02/28, HDFFV-11033)
+
+    Tools
+    -----
+    - The tools library was updated by standardizing the error stack process.
+
+      General sequence is:
+          h5tools_setprogname(PROGRAMNAME);
+          h5tools_setstatus(EXIT_SUCCESS);
+          h5tools_init();
+          ... process the command-line (check for error-stack enable) ...
+          h5tools_error_report();
+          ... (do work) ...
+          h5diff_exit(ret);
+
+      (ADB - 2020/07/20, HDFFV-11066)
+
+    - h5diff fixed a command line parsing error.
+
+      h5diff would ignore the argument to -d (delta) if it is smaller than DBL_EPSILON.
+      The macro H5_DBL_ABS_EQUAL was removed and a direct value comparision was used.
+
+      (ADB - 2020/07/20, HDFFV-10897)
+
+    - h5diff added a command line option to ignore attributes.
+
+      h5diff would ignore all objects with a supplied path if the exclude-path argument is used.
+      Adding the exclude-attribute argument will only eclude attributes, with the supplied path,
+      from comparision.
+
+      (ADB - 2020/07/20, HDFFV-5935)
+
+    - h5diff added another level to the verbose argument to print filenames.
+
+      Added verbose level 3 that is level 2 plus the filenames. The levels are:
+          0 : Identical to '-v' or '--verbose'
+          1 : All level 0 information plus one-line attribute status summary
+          2 : All level 1 information plus extended attribute status report
+          3 : All level 2 information plus file names
+
+      (ADB - 2020/07/20, HDFFV-10005)
+
+    - h5repack was fixed to repack the reference attributes properly.
+      The code line that checks if the update of reference inside a compound
+      datatype is misplaced outside the code block loop that carries out the
+      check. In consequence, the next attribute that is not the reference
+      type was repacked again as the reference type and caused the failure of
+      repacking. The fix is to move the corresponding code line to the correct
+      code block.
+
+      (KY -2020/02/10, HDFFV-11014)
+
+    High-Level APIs:
+    ------
+    - The H5DSis_scale function was updated to return "not a dimension scale" (0)
+      instead of failing (-1), when CLASS or DIMENSION_SCALE attributes are
+      not written according to Dimension Scales Specification.
+
+     (EIP - 2020/08/12, HDFFV-10436)
+
+    Fortran High-Level APIs:
+    ------

+
+    Testing
+    -------
+    - Stopped java/test/junit.sh.in installing libs for testing under ${prefix}
+
+      Lib files needed are now copied to a subdirectory in the java/test
+      directory, and on Macs the loader path for libhdf5.xxxs.so is changed
+      in the temporary copy of libhdf5_java.dylib.

+
+    At present, metadata cache images may not be generated by parallel
+    applications.  Parallel applications can read files with metadata cache
+    images, but since this is a collective operation, a deadlock is possible
+    if one or more processes do not participate.
+
+    Two tests fail attempting collective writes with OpenMPI 3.0.0/GCC-7.2.0-2.29:

+
+    CPP ptable test fails on both VS2017 and VS2019 with Intel compiler, JIRA

+
+CMake vs. Autotools installations
+=================================
+While both build systems produce similar results, there are differences.
+Each system produces the same set of folders on linux (only CMake works
+on standard Windows); bin, include, lib and share. Autotools places the
+COPYING and RELEASE.txt file in the root folder, CMake places them in
+the share folder.
+
+The bin folder contains the tools and the build scripts. Additionally, CMake
+creates dynamic versions of the tools with the suffix "-shared". Autotools
+installs one set of tools depending on the "--enable-shared" configuration
+option.
+  build scripts
+  -------------
+  Autotools: h5c++, h5cc, h5fc
+  CMake: h5c++, h5cc, h5hlc++, h5hlcc
+
+The include folder holds the header files and the fortran mod files. CMake
+the share folder.
+
+The bin folder contains the tools and the build scripts. Additionally, CMake
+places the fortran mod files into separate shared and static subfolders,
+while Autotools places one set of mod files into the include folder. Because
+CMake produces a tools library, the header files for tools will appear in
+the include folder.
+
+The lib folder contains the library files, and CMake adds the pkgconfig
+subfolder with the hdf5*.pc files used by the bin/build scripts created by
+the CMake build. CMake separates the C interface code from the fortran code by
+creating C-stub libraries for each Fortran library. In addition, only CMake
+installs the tools library. The names of the szip libraries are different
+between the build systems.
+
+The share folder will have the most differences because CMake builds include
+a number of CMake specific files for support of CMake's find_package and support
+for the HDF5 Examples CMake project.

+
+New Features
+============
+
+    Configuration:
+    -------------
+    - Update CMake for VS2019 support
+
+      CMake added support for VS2019 in version 3.15. Changes to the CMake
+      generator setting required changes to scripts. Also updated version
+      references in CMake files as necessary.
+
+      (ADB - 2019/11/18, HDFFV-10962)
+
+    - Update CMake options to match new autotools options
+
+      Add configure options (autotools - CMake):
+            enable-asserts       HDF5_ENABLE_ASSERTS
+            enable-symbols       HDF5_ENABLE_SYMBOLS
+            enable-profiling     HDF5_ENABLE_PROFILING
+            enable-optimization  HDF5_ENABLE_OPTIMIZATION
+      In addition NDEBUG is no longer forced defined and relies on the CMake
+      process.
+
+      (ADB - 2019/10/07, HDFFV-100901, HDFFV-10637, TRILAB-97)
+
+    - Update CMake tests to use FIXTURES
+
+      CMake test fixtures allow setup/cleanup tests and other dependency
+      requirements as properties for tests. This is more flexible for
+      modern CMake code.
+
+      (ADB - 2019/07/23, HDFFV-10529)
+
+    - Windows PDB files are always installed
+
+      There are build configuration or flag settings for Windows that may not
+      generate PDB files. If those files are not generated then the install
+      utility will fail because those PDB files are not found. An optional
+      variable, DISABLE_PDB_FILES, was added to not install PDB files.
+
+      (ADB - 2019/07/17, HDFFV-10424)
+
+    - Add mingw CMake support with a toolchain file
+
+      There have been a number of mingw issues that have been linked under
+      HDFFV-10845. It has been decided to implement the CMake cross-compiling
+      technique of toolchain files. We will use a linux platform with the mingw
+      compiler stack for testing. Only the C language is fully supported, and
+      the error tests are skipped. The C++ language works for static but shared
+      builds have a shared library issue with the mingw Standard Exception Handling
+      library, which is not available on Windows. Fortran has a common cross-compile
+      problem with the fortran configure tests.
+
+      (ADB - 2019/07/12, HDFFV-10845, HDFFV-10595)
+
+    - Windows PDB files are installed incorrectly
+
+      For static builds, the PDB files for windows should be installed next
+      to the static libraries in the lib folder. Also the debug versions of
+      libraries and PDB files are now correctly built using the default
+      CMAKE_DEBUG_POSTFIX setting.
+
+      (ADB - 2019/07/09, HDFFV-10581)
+
+    - Add option to build only shared libs
+
+      A request was made to prevent building static libraries and only build
+      shared.  A new option was added to CMake, ONLY_SHARED_LIBS, which will
+      skip building static libraries. Certain utility functions will build with
+      static libs but are not published. Tests are adjusted to use the correct
+      libraries depending on SHARED/STATIC settings.
+
+      (ADB - 2019/06/12, HDFFV-10805)
+
+    - Add options to enable or disable building tools and tests
+
+      Configure options --enable-tests and --enable-tools were added for
+      autotools configure.  These options are enabled by default, and can be
+      disabled with either --disable-tests (or tools) or --enable-tests=no
+      (or --enable-tools=no).  Build time is reduced ~20% when tools are
+      disabled, 35% when tests are disabled, 45% when both are disabled.
+      Re-enabling them after the initial build requires running configure
+      again with the option(s) enabled.
+
+      (LRK - 2019/06/12, HDFFV-9976)
+
+    - Change tools tests to search the error stack
+
+      There are some use cases which can cause the error stack of tools to be
+      different then the expected output. These tests now use grepTest.cmake;
+      this was changed to allow the error file to be searched for an expected string.
+
+      (ADB - 2019/04/15, HDFFV-10741)
+
+
+    Library:
+    --------
+    - Added S3 and HDFS Virtual File Drivers (VFDs) to HDF5
+
+      These new VFDs have been introduced in HDF5-1.10.6.  Instructions to
+      enable them when configuring HDF5 on Linux and Mac may be found at
+      https://portal.hdfgroup.org/display/HDF5/Virtual+File+Drivers+-+S3+and+HDFS.
+
+      Installing on Windows requires CMake 3.13 and the following additional setup.
+            Install openssl library (with dev files);
+            from "Shining Light Productions". msi package preferred.
+
+            PATH should have been updated with the installation dir.
+            set ENV variable OPENSSL_ROOT_DIR to the installation dir.
+            set ENV variable OPENSSL_CONF to the cfg file, likely %OPENSSL_ROOT_DIR%\bin\openssl.cfg
+            Install libcurl library (with dev files);
+            download the latest released version using git: https://github.com/curl/curl.git
+
+            Open a Visual Studio Command prompt
+            change to the libcurl root folder
+            run the "buildconf.bat" batch file
+            change to the winbuild directory
+            nmake /f Makefile.vc mode=dll MACHINE=x64
+            copy libcurl-vc-x64-release-dll-ipv6-sspi-winssl dir to C:\curl (installation dir)
+            set ENV variable CURL_ROOT to C:\curl (installation dir)
+            update PATH ENV variable to %CURL_ROOT%\bin (installation bin dir).
+            the aws credentials file should be in %USERPROFILE%\.aws folder
+            set the ENV variable "HDF5_ROS3_TEST_BUCKET_URL=https://s3.us-east-2.amazonaws.com/hdf5ros3"
+
+      (ADB - 2019/09/12, HDFFV-10854)
+
+    C++ Library:
+    ------------
+    - Added new wrappers for H5Pset/get_create_intermediate_group()
+        LinkCreatPropList::setCreateIntermediateGroup()
+        LinkCreatPropList::getCreateIntermediateGroup()
+
+      (BMR - 2019/04/22, HDFFV-10622)
+
+
+    Java Library:
+    ----------------
+    - Fixed a failure in JUnit-TestH5P on 32-bit architectures
+
+      (JTH - 2019/04/30)
+
+
+Support for new platforms, languages and compilers.
+=======================================
+    - CMake added support for VS2019 in version 3.15. Updated scripts.
+
+    - macOS 10.13.6 Darwin 17.7.0 with Apple clang LLVM version 10.0.0
+
+    - macOS 10.14.6 Darwin 18.7.0 with Apple clang LLVM version 10.0.1
+
+
+Bug Fixes since HDF5-1.10.5 release
+==================================
+
+    Library
+    -------
+    - Improved performance when creating a large number of small datasets by
+      retrieving default property values from the API context instead of doing
+      skip list searches. More work is required to achieve parity with HDF5 1.8.
+
+      (CJH - 2019/12/10, HDFFV-10658)
+
+    - Fixed user-created data access properties not existing in the property list
+      returned by H5Dget_access_plist. Thanks to Steven Varga for submitting a
+      reproducer and a patch.
+
+      (CJH - 2019/12/9, HDFFV-10934)
+
+    - Inappropriate linking with deprecated MPI C++ libraries
+
+      HDF5 does not define *_SKIP_MPICXX in the public headers, so applications
+      can inadvertently wind up linking to the deprecated MPI C++ wrappers.
+
+      MPICH_SKIP_MPICXX and OMPI_SKIP_MPICXX have both been defined in H5public.h
+      so this should no longer be an issue. HDF5 makes no use of the deprecated
+      MPI C++ wrappers.
+
+      (DER - 2019/09/17, HDFFV-10893)
+
+    - fcntl(2)-based file locking incorrectly passed the lock argument struct
+      instead of a pointer to the struct, causing errors on systems where
+      flock(2) is not available.
+
+      File locking is used when files are opened to enforce SWMR semantics. A
+      lock operation takes place on all file opens unless the
+      HDF5_USE_FILE_LOCKING environment variable is set to the string "FALSE".
+      flock(2) is preferentially used, with fcntl(2) locks as a backup if
+      flock(2) is unavailable on a system (if neither is available, the lock
+      operation fails). On these systems, the file lock will often fail, which
+      causes HDF5 to not open the file and report an error.
+
+      This bug only affects POSIX systems. Win32 builds on Windows use a no-op
+      locking call which always succeeds. Systems which exhibit this bug will
+      have H5_HAVE_FCNTL defined but not H5_HAVE_FLOCK in the configure output.
+
+      This bug affects HDF5 1.10.0 through 1.10.5.
+
+      fcntl(2)-based file locking now correctly passes the struct pointer.
+
+      (DER - 2019/08/27, HDFFV-10892)
+
+    - Fixed a bug caused by a bad tag value when condensing object header
+      messages
+
+      There was an assertion failure when moving messages from running a
+      user test program with library release HDF5 1.10.4. It was because
+      the tag value (object header's address) was not set up when entering
+      the library routine H5O__chunk_update_idx(), which eventually
+      verifies the metadata tag value when protecting the object header.
+
+      The problem was fixed by replacing FUNC_ENTER_PACKAGE in H5O__chunk_update_idx()
+      with FUNC_ENTER_PACKAGE_TAG(oh->cache_info.addr) to set up the metadata tag.
+
+      (VC - 2019/08/23, HDFFV-10873)
+
+    - Fixed the test failure from test_metadata_read_retry_info() in
+      test/swmr.c
+
+      The test failure is due to an incorrect number of bins returned for
+      retry info (info.nbins).  The # of bins expected for 101 read attempts
+      is 3 instead of 2.  The routine H5F_set_retries() in src/H5Fint.c
+      calculates the # of bins by first obtaining the log10 value for
+      (read attempts - 1).  For PGI/19, the log10 value for 100 read attempts
+      is 1.9999999999999998 instead of 2.00000.  When casting the log10 value
+      to unsigned later on, the decimal part is chopped off causing the test
+      failure.
+
+      This was fixed by obtaining the rounded integer value (HDceil) for the
+      log10 value of read attempts first before casting the result to unsigned.
+
+      (VC - 2019/8/14, HDFFV-10813)
+
+    - Fixed an issue when creating a file with non-default file space info
+      together with library high bound setting to H5F_LIBVER_V18.
+
+      When setting non-default file space info in fcpl via
+      H5Pset_file_space_strategy() and then creating a file with both high and
+      low library bounds set to H5F_LIBVER_V18 in fapl, the library succeeds in
+      creating the file.  File creation should fail because the feature of
+      setting non-default file space info does not exist in library release 1.8
+      or earlier.
+
+      This was fixed by setting and checking the proper version in the file
+      space info message based on the library low and high bounds when creating
+      and opening the HDF5 file.
+
+      (VC - 2019/6/25, HDFFV-10808)
+
+    - Fixed an issue where copying a version 1.8 dataset between files using
+      H5Ocopy fails due to an incompatible fill version
+
+      When using the HDF5 1.10.x H5Ocopy() API call to copy a version 1.8
+      dataset to a file created with both high and low library bounds set to
+      H5F_LIBVER_V18, the H5Ocopy() call will fail with the error stack indicating
+      that the fill value version is out of bounds.
+
+      This was fixed by changing the fill value message version to H5O_FILL_VERSION_3
+      (from H5O_FILL_VERSION_2) for H5F_LIBVER_V18.
+
+      (VC - 2019/6/14, HDFFV-10800)
+
+    - Fixed a bug that would cause an error or cause fill values to be
+      incorrectly read from a chunked dataset using the "single chunk" index if
+      the data was held in cache and there was no data on disk.
+
+      (NAF - 2019/03/06)
+
+    - Fixed a bug that could cause an error or cause fill values to be
+      incorrectly read from a dataset that was written to using H5Dwrite_chunk
+      if the dataset was not closed after writing.
+
+      (NAF - 2019/03/06, HDFFV-10716)
+
+    - Fixed memory leak in scale offset filter
+
+      In a special case where the MinBits is the same as the number of bits in
+      the datatype's precision, the filter's data buffer was not freed, causing
+      the memory usage to grow. In general the buffer was freed correctly.  The
+      Minbits are the minimal number of bits to store the data values.  Please
+      see the reference manual for H5Pset_scaleoffset for the details.
+
+      (RL - 2019/3/4, HDFFV-10705)
+
+
+    Configuration
+    -------------
+    - Correct option for default API version
+
+      CMake options for default API version are not mutually exclusive.
+      Change the multiple BOOL options to a single STRING option with the
+      strings; v16, v18, v110.
+
+      (ADB - 2019/08/12, HDFFV-10879)
+
+    Tools
+    -----
+    - h5repack was fixed to repack datasets with external storage
+      to other types of storage.
+
+      New test added to repack files and verify the correct data using h5diff.
+
+      (JS - 2019/09/25, HDFFV-10408)

+
+Known Problems
+==============
+    CMake files do not behave correctly with paths containing spaces.
+    Do not use spaces in paths because the required escaping for handling spaces
+    results in very complex and fragile build files.
+    ADB - 2019/05/07
+
+    At present, metadata cache images may not be generated by parallel
+    applications.  Parallel applications can read files with metadata cache
+    images, but since this is a collective operation, a deadlock is possible
+    if one or more processes do not participate.
+
+    Three tests fail with OpenMPI 3.0.0/GCC-7.2.0-2.29:
+        testphdf5 (ecdsetw, selnone, cchunk1, cchunk3, cchunk4, and actualio)
+        t_shapesame (sscontig2)
+        t_pflush1/fails on exit
+    The first two tests fail attempting collective writes.
+
+    Parallel builds using OpenMPI 3.03 or later and romio fail several tests
+    with collective writes or compression that will not fail when ompio is used
+    instead of romio.  This can be done by adding "--mca io ompio" to the mpirun
+    command.  For example, in autotools builds RUNPARALLEL can be set to
+    "mpirun --mca io ompio -n 6" provided ompio is installed.
+
+    CPP ptable test fails on VS2017 with Intel compiler, JIRA issue: HDFFV-10628.
+    This test will pass with VS2015 with Intel compiler.
+
+    Older MPI libraries such as OpenMPI 2.0.1 and MPICH 2.1.5 were tested
+    while attempting to resolve the Jira issue: HDFFV-10540.
+    The known problems of reading or writing > 2GBs when using MPI-2 was
+    partially resolved with the MPICH library. The proposed support recognizes
+    IO operations > 2GB and if the datatype is not a derived type, the library
+    breaks the IO into chunks which can be input or output with the existing
+    MPI 2 limitations, i.e. size reporting and function API size/count
+    arguments are restricted to be 32 bit integers.  For derived types larger
+    than 2GB, MPICH 2.1.5 fails while attempting to read or write data.
+    OpenMPI in contrast, implements MPI-3 APIs even in the older releases
+    and thus does not suffer from the 32 bit size limitation described here.
+    OpenMPI releases prior to v3.1.3 appear to have other datatype issues however,
+    e.g. within a single parallel test (testphdf5) the subtests (cdsetr, eidsetr)
+    report data verfication errors before eventually aborting.
+    The most recent versions of OpenMPI (v3.1.3 or newer) have evidently
+    resolved these isses and parallel HDF5 testing does not currently report
+    errors though occasional hangs have been observed.
+
+    Known problems in previous releases can be found in the HISTORY*.txt files
+    in the HDF5 source. Please report any new problems found to
+    help@hdfgroup.org.
+
+
+CMake vs. Autotools installations
+=================================
+While both build systems produce similar results, there are differences.
+Each system produces the same set of folders on linux (only CMake works
+on standard Windows); bin, include, lib and share. Autotools places the
+COPYING and RELEASE.txt file in the root folder, CMake places them in
+the share folder.
+
+The bin folder contains the tools and the build scripts. Additionally, CMake
+creates dynamic versions of the tools with the suffix "-shared". Autotools
+installs one set of tools depending on the "--enable-shared" configuration
+option.
+  build scripts
+  -------------
+  Autotools: h5c++, h5cc, h5fc
+  CMake: h5c++, h5cc, h5hlc++, h5hlcc
+
+The include folder holds the header files and the fortran mod files. CMake
+places the fortran mod files into separate shared and static subfolders,
+while Autotools places one set of mod files into the include folder. Because
+CMake produces a tools library, the header files for tools will appear in
+the include folder.
+
+The lib folder contains the library files, and CMake adds the pkgconfig
+subfolder with the hdf5*.pc files used by the bin/build scripts created by
+the CMake build. CMake separates the C interface code from the fortran code by
+creating C-stub libraries for each Fortran library. In addition, only CMake
+installs the tools library. The names of the szip libraries are different
+between the build systems.
+
+The share folder will have the most differences because CMake builds include
+a number of CMake specific files for support of CMake's find_package and support
+for the HDF5 Examples CMake project.

+
+New Features
+============
+
+    Configuration:
+    -------------
+    - Cross compile on mutrino and other Cray XC40 systems.
+
+      Added support for CMake options to use CrayLinuxEnvironment, craype-mic-knl
+      module for building with craype-haswell module for configuration, and
+      batch scripts in bin/batch for use with sbatch or bsub to run tests in
+      batch jobs on compute nodes.  An instruction file README_HPC describing
+      the use of these options was added in release_docs.
+
+      (LRK - 2019/02/18, TRILABS-34)
+
+    - Rework CMake command files to fix MPI testing.
+
+      Added setup fixture to remove any test generated files and added DEPENDS
+      to test properties to execute tests in order expected.
+
+      (ADB - 2019/02/14, TRILABS-111)
+
+    - Disable SZIP or ZLIB options if TGZ files are not available.
+
+      Changed the TGZ option for SZip and ZLib to disable the options
+      if the source tar.gz files are not found.
+
+      (ADB - 2019/02/05, HDFFV-10697)
+
+    - Added a new option to enable/disable using pread/pwrite instead of
+      read/write in the sec2, log, and core VFDs.
+
+      This option is enabled by default when pread/pwrite are detected.
+
+      Autotools:    --enable-preadwrite
+      CMake:        HDF5_ENABLE_PREADWRITE
+
+      (DER - 2019/02/03, HDFFV-10696)
+
+    - Rework CMake versioning for OSX platforms.
+
+      Changed the current_version and compatibility_version flags from optional
+      with HDF5_BUILD_WITH_INSTALL_NAME to always setting the flags for OSX.
+
+      (ADB - 2019/01/22, HDFFV-10685)
+
+    - Rework CMake command files to eliminate developer CMP005 warning
+
+      Use variables without quotes in if () statements.
+
+      (ADB - 2019/01/18, TILABS-105)
+
+    - Rework CMake configure files to eliminate developer CMP0075 warning
+
+      Renamed varname to HDF5_REQUIRED_LIBRARIES as the contents were not
+      required for configuration. Also moved check includes calls to top of
+      files.
+
+      (ADB - 2019/01/03, HDFFV-10546)
+
+    - Keep stderr and stdout separate in tests
+
+      Changed test handling of output capture. Tests now keep the stderr
+      output separate from the stdout output. It is up to the test to decide
+      which output to check against a reference. Also added the option
+      to grep for a string in either output.
+
+      (ADB - 2018/12/12, HDFFV-10632)
+
+    - Incorrectly installed private header files were removed from
+      CMake installs.
+
+      The CMake build files incorrectly flagged the following header files
+      as public and installed them. They are private and will no longer be
+      installed.
+
+        HDF5 library private package files (H5Xpkg.h)
+        H5Edefin.h
+        H5Einit.h
+        H5Eterm.h
+        H5LTparse.h
+        h5diff.h
+        h5tools_dump.h
+        h5tools.h
+        h5tools_ref.h
+        h5tools_str.h
+        h5tools_utils.h
+        h5trav.h
+
+      (DER - 2018/10/26, HDFFV-10614, 10609)
+
+    - Autotools installs now install H5FDwindows.h
+
+      This is simply to align the installed header files between the
+      autotools and CMake. H5FDwindows.h has no functionality on
+      non-Windows systems.
+
+      (DER - 2018/10/26, HDFFV-10614)
+
+
+    Library:
+    --------
+    - The sec2, log, and core VFDs can now use pread/pwrite instead of
+      read/write.
+
+      pread and pwrite do not change the file offset, a feature that was
+      requested by a user working with a multi-threaded application.
+
+      The option to configure this feature is described above.
+
+      (DER - 2019/02/03, HDFFV-10696)
+
+    - Add ability to minimze dataset object headers.
+
+      Creation of many, very small datasets resulted in extensive file bloat
+      due to extra space in the dataset object headers -- this space is
+      allocated by default to allow for the insertion of a small number of
+      attributes within the object header and not require a continuation
+      block, an unnecessary provision in the target use case.
+
+      Inform the library to expect no attributes on created datasets, and to
+      allocate the least space possible for the object headers.
+      NOTE: A continuation block is created if attributes are added to a
+      'minimized' dataset, which can reduce performance.
+      NOTE: Some extra space is allocated for attributes essential to the
+      correct behavior of the object header (store creation times, e.g.). This
+      does not violate the design principle, as the space is calculated and
+      allocated as needed at the time of dataset object header creation --
+      unused space is not generated.
+      New API calls:
+      H5Fget_dset_no_attrs_hint
+      H5Fset_dset_no_attrs_hint
+      H5Pget_dset_no_attrs_hint
+      H5Pset_dset_no_attrs_hint
+
+      (JOS - 2019/01/04, TRILAB-45)
+
+    - Added new chunk query functions
+
+      The following public functions were added to discover information about
+      the chunks in an HDF5 file.
+        herr_t H5Dget_num_chunks(dset_id, fspace_id, *nchunks)
+        herr_t H5Dget_chunk_info_by_coord(dset_id, *coord, *filter_mask, *addr, *size)
+        herr_t H5Dget_chunk_info(dset_id, fspace_id, index, *coord, *filter_mask, *addr, *size)
+
+      (BMR - 2018/11/07, HDFFV-10615)
+
+    - Several empty public header files where removed from the distribution
+
+      The following files were empty placeholders. They are for internal
+      packages that are unlikely to ever have public functionality and have
+      thus been removed.
+
+        H5Bpublic.h
+        H5B2public.h
+        H5FSpublic.h
+        H5HFpublic.h
+        H5HGpublic.h
+        H5HLpublic.h
+

+
+
+     Parallel Library:
+    -----------------
+    - Changed the default behavior in parallel when reading the same dataset in its entirety
+      (i.e. H5S_ALL dataset selection) which is being read by all the processes collectively.
+      The dataset must be contiguous, less than 2GB, and of an atomic datatype.
+      The new behavior is the HDF5 library will use an MPI_Bcast to pass the data read from
+      the disk by the root process to the remain processes in the MPI communicator associated
+      with the HDF5 file.
+
+      (MSB - 2019/01/02, HDFFV-10652)
+
+    - All MPI-1 API calls have been replaced with MPI-2 equivalents.
+
+      This was done to better support OpenMPI, as default builds no longer
+      include MPI-1 support (as of OpenMPI 4.0).
+
+      (DER - 2018/12/30, HDFFV-10566)
+
+    Fortran Library:
+    ----------------
+    - Added wrappers for dataset object header minimization calls.
+      (see the note for TRILAB-45, above)
+
+      New API calls:
+
+      h5fget_dset_no_attrs_hint_f
+      h5fset_dset_no_attrs_hint_f
+      h5pget_dset_no_attrs_hint_f
+      h5pset_dset_no_attrs_hint_f
+
+      (DER - 2019/01/09, TRILAB-45)
+
+    - Added new Fortran derived type, c_h5o_info_t, which is interoperable with
+      C's h5o_info_t. This is needed for callback functions which
+      pass C's h5o_info_t data type definition.
+
+      (MSB, 2019/01/08, HDFFV-10443)
+
+    - Added new Fortran API, H5gmtime, which converts (C) 'time_t' structure
+      to Fortran DATE AND TIME storage format.
+
+      (MSB, 2019/01/08, HDFFV-10443)
+
+    - Added new Fortran 'fields' optional parameter to: h5ovisit_f, h5oget_info_by_name_f,
+      h5oget_info, h5oget_info_by_idx and h5ovisit_by_name_f.
+
+      (MSB, 2019/01/08, HDFFV-10443)
+
+    C++ Library:
+    ------------
+    - Added new function to the C++ interface
+
+      Added wrapper for H5Ovisit2:
+          H5Object::visit()
+
+      (BMR - 2019/02/14, HDFFV-10532)

+    ----------------
+    - Rewrote the JNI error handling to be much cleaner
+
+      (JTH - 2019/02/12)
+
+    - Add new functions to java interface
+
+      Added wrappers for:
+      H5Fset_libver_bounds
+      H5Fget_dset_no_attrs_hint/H5Fset_dset_no_attrs_hint

+
+    - Fix java unit tests when Time is a natural number
+
+      Time substitution in java/test/junit.sh.in doesn't
+      handle the case when Time is a natural number. Fixed
+      the regular expression.
+
+      (ADB - 2019/01/07, HDFFV-10674)
+
+    - Duplicate the data read/write functions of Datasets for Attributes.
+
+      Region references could not be displayed for attributes as they could
+      for datasets. Datasets had overloaded read and write functions for different
+      datatypes that were not available for attributes. After adding similar
+      functions, attribute region references work normally.

+
+
+    Tools:
+    ------
+    - The h5repart -family-to-sec2 argument was changed to -family-to-single
+
+      In order to better support other single-file VFDs which could work with
+      h5repart, the -family-to-sec2 argument was renamed to -family-to-single.
+      This is just a name change and the functionality of the argument has not
+      changed.
+
+      The -family-to-sec2 argument has been kept for backwards-compatibility.
+      This argument should be considered deprecated.

+Bug Fixes since HDF5-1.10.4 release
+==================================
+
+    Library
+    -------
+    - Fix hangs with collective metadata reads during chunked dataset I/O
+
+      In the parallel library, it was discovered that when a particular
+      sequence of operations following a pattern of:
+
+      "write to chunked dataset" -> "flush file" -> "read from dataset"
+
+      occurred with collective metadata reads enabled, hangs could be
+      observed due to certain MPI ranks not participating in the collective
+      metadata reads.
+
+      To fix the issue, collective metadata reads are now disabled during
+      chunked dataset raw data I/O.
+
+      (JTH - 2019/02/11, HDFFV-10563, HDFFV-10688)
+
+    - Performance issue when closing an object
+
+      The slow down is due to the search of the "tag_list" to find
+      out the "corked" status of an object and "uncork" it if so.
+
+      Improve performance by skipping the search of the "tag_list"
+      if there are no "corked" objects when closing an object.
+
+      (VC - 2019/02/06)
+
+    - Uninitialized bytes from a type conversion buffer could be written
+      to disk in H5Dwrite calls where type conversion takes place
+      and the type conversion buffer was created by the HDF5 library.
+
+      When H5Dwrite is called and datatype conversion must be performed,
+      the library will create a temporary buffer for type conversion if
+      one is not provided by the user via H5Pset_buffer. This internal
+      buffer is allocated via malloc and contains uninitialized data. In
+      some datatype conversions (float to long double, possibly others),
+      some of this uninitialized data could be written to disk.
+
+      This was flagged by valgrind in the dtransform test and does not
+      appear to be a common occurrence (it is flagged in one test out
+      of the entire HDF5 test suite).
+
+      Switching to calloc fixed the problem.
+
+      (DER - 2019/02/03, HDFFV-10694)
+
+    - There was missing protection against division by zero reported to
+      The HDF Group as issue #CVE-2018-17434.
+
+      Protection against division by zero was added to address the issue
+      #CVE-2018-17434.
+
+      (BMR - 2019/01/29, HDFFV-10586)
+
+    - The issue CVE-2018-17437 was reported to The HDF Group
+
+      Although CVE-2018-17437 reported a memory leak, the actual issue
+      was invalid read. It was found that the attribute name length
+      in an attribute message was corrupted, which caused the buffer
+      pointer to be advanced too far and later caused an invalid read.
+
+      A check was added to detect when the attribute name or its length
+      was corrupted and report the potential of data corruption.
+
+      (BMR - 2019/01/29, HDFFV-10588)
+
+    - H5Ewalk did not stop when it was supposed to
+
+      H5Ewalk was supposed to stop when the callback function stopped
+      even though the errors in the stack were not all visited, but it
+      did not.  This problem is now fixed.
+
+      (BMR - 2019/01/29, HDFFV-10684)
+
+    - Revert H5Oget_info* and H5Ovisit* functions
+
+      In 1.10.3 new H5Oget_info*2 and H5Ovisit*2 functions were
+      added for performance. Inadvertently, the original functions;
+          H5Oget_info,
+          H5Oget_info_by_name,
+          H5Oget_info_by_idx,
+          H5Ovisit,
+          H5Ovisit_by_name
+      were versioned to H5Oget_info*1 and H5Ovisit*1. This
+      broke the API compatibility for a maintenance release. The
+      original functions have been restored.
+
+      (ADB - 2019/01/24, HDFFV-10686)
+
+    - Fixed a potential invalid memory access and failure that could occur when
+      decoding an unknown object header message (from a future version of the
+      library).
+
+      (NAF - 2019/01/07)
+
+    - Deleting attributes in dense storage
+
+      The library aborts with "infinite loop closing library" after
+      attributes in dense storage are created and then deleted.
+
+      When deleting the attribute nodes from the name index v2 B-tree,
+      if an attribute is found in the intermediate B-tree nodes,
+      which may be merged/redistributed in the process, we need to
+      free the dynamically allocated spaces for the intermediate
+      decoded attribute.
+
+      (VC - 2018/12/26, HDFFV-10659)
+
+    - There was missing protection against division by zero reported to
+      The HDF Group as issue #CVE-2018-17233.
+
+      Protection against division by zero was added to address the issue
+      #CVE-2018-17233.  In addition, several similar occurrences in the same
+      file were fixed as well.
+
+      (BMR - 2018/12/23, HDFFV-10577)
+
+    - Fixed an issue where the parallel filters tests would fail
+      if zlib was not available on the system. Until support can
+      be added in the tests for filters beyond gzip/zlib, the tests
+      will be skipped if zlib is not available.
+
+      (JTH - 2018/12/05)
+
+    - A bug was discovered in the parallel library where an application
+      would eventually consume all of the available MPI communicators
+      when continually writing to a compressed dataset in parallel. This
+      was due to internal copies of an HDF5 File Access Property List,
+      which each contained a copy of the MPI communicator, not being
+      closed at the end of each write operation. This problem was
+      exacerbated by larger numbers of processors.
+
+      (JTH - 2018/12/05, HDFFV-10629)
+
+
+    Fortran
+    --------
+    - Fixed issue with Fortran not returning h5o_info_t field values
+      meta_size%attr%index_size and  meta_size%attr%heap_size.
+
+      (MSB, 2019/01/08, HDFFV-10443)
+
+    - Added symbolic links libhdf5_hl_fortran.so to libhdf5hl_fortran.so and
+      libhdf5_hl_fortran.a to libhdf5hl_fortran.a in hdf5/lib directory for
+      autotools installs.  These were added to match the name of the files
+      installed by cmake and the general pattern of hl lib files.  We will
+      change the names of the installed lib files to the matching name in
+      the next major release.
+
+      (LRK - 2019/01/04, HDFFV-10596)
+
+    - Made Fortran specific subroutines PRIVATE in generic procedures.
+
+      Affected generic procedures were functions in H5A, H5D, H5P, H5R and H5T.
+
+      (MSB, 2018/12/04, HDFFV-10511)
+
+
+    Testing
+    -------
+    - Fixed a test failure in testpar/t_dset.c caused by
+      the test trying to use the parallel filters feature
+      on MPI-2 implementations.

+
+Known Problems
+==============
+
+    At present, metadata cache images may not be generated by parallel
+    applications.  Parallel applications can read files with metadata cache
+    images, but since this is a collective operation, a deadlock is possible
+    if one or more processes do not participate.
+
+    Three tests fail with OpenMPI 3.0.0/GCC-7.2.0-2.29:
+        testphdf5 (ecdsetw, selnone, cchunk1, cchunk3, cchunk4, and actualio)
+        t_shapesame (sscontig2)
+        t_pflush1/fails on exit
+    The first two tests fail attempting collective writes.
+
+    CPP ptable test fails on VS2017 with Intel compiler, JIRA issue: HDFFV-10628.
+    This test will pass with VS2015 with Intel compiler.
+
+    Older MPI libraries such as OpenMPI 2.0.1 and MPICH 2.1.5 were tested
+    while attempting to resolve the Jira issue: HDFFV-10540.
+    The known problems of reading or writing > 2GBs when using MPI-2 was
+    partially resolved with the MPICH library. The proposed support recognizes
+    IO operations > 2GB and if the datatype is not a derived type, the library
+    breaks the IO into chunks which can be input or output with the existing
+    MPI 2 limitations, i.e. size reporting and function API size/count
+    arguments are restricted to be 32 bit integers.  For derived types larger
+    than 2GB, MPICH 2.1.5 fails while attempting to read or write data.
+    OpenMPI in contrast, implements MPI-3 APIs even in the older releases
+    and thus does not suffer from the 32 bit size limitation described here.
+    OpenMPI releases prior to v3.1.3 appear to have other datatype issues however,
+    e.g. within a single parallel test (testphdf5) the subtests (cdsetr, eidsetr)
+    report data verfication errors before eventually aborting.
+    The most recent versions of OpenMPI (v3.1.3 or newer) have evidently
+    resolved these isses and parallel HDF5 testing does not currently report
+    errors though occasional hangs have been observed.
+
+    Known problems in previous releases can be found in the HISTORY*.txt files
+    in the HDF5 source. Please report any new problems found to
+    help@hdfgroup.org.
+
+
+CMake vs. Autotools installations
+=================================
+While both build systems produce similar results, there are differences.
+Each system produces the same set of folders on linux (only CMake works
+on standard Windows); bin, include, lib and share. Autotools places the
+COPYING and RELEASE.txt file in the root folder, CMake places them in
+the share folder.
+
+The bin folder contains the tools and the build scripts. Additionally, CMake
+creates dynamic versions of the tools with the suffix "-shared". Autotools
+installs one set of tools depending on the "--enable-shared" configuration
+option.
+  build scripts
+  -------------
+  Autotools: h5c++, h5cc, h5fc
+  CMake: h5c++, h5cc, h5hlc++, h5hlcc
+
+The include folder holds the header files and the fortran mod files. CMake
+places the fortran mod files into separate shared and static subfolders,
+while Autotools places one set of mod files into the include folder. Because
+CMake produces a tools library, the header files for tools will appear in
+the include folder.
+
+The lib folder contains the library files, and CMake adds the pkgconfig
+subfolder with the hdf5*.pc files used by the bin/build scripts created by
+the CMake build. CMake separates the C interface code from the fortran code by
+creating C-stub libraries for each Fortran library. In addition, only CMake
+installs the tools library. The names of the szip libraries are different
+between the build systems.
+
+The share folder will have the most differences because CMake builds include
+a number of CMake specific files for support of CMake's find_package and support
+for the HDF5 Examples CMake project.

+New Features
+============
+
+    Configuration:
+    -------------
+    - Update CMake tests to use FIXTURES
+
+      CMake test fixtures allow setup/cleanup tests and other dependency
+      requirements as properties for tests. This is more flexible for
+      modern CMake code.
+
+      (ADB - 2019/07/23, HDFFV-10529)
+
+    - Windows PDB files are always installed
+
+      There are build configuration or flag settings for Windows that may not
+      generate PDB files. If those files are not generated then the install
+      utility will fail because those PDB files are not found. An optional
+      variable, DISABLE_PDB_FILES, was added to not install PDB files.
+
+      (ADB - 2019/07/17, HDFFV-10424)
+
+    - Add mingw CMake support with a toolchain file
+
+      There has been a number of mingw issues that has been linked under
+      HDFFV-10845. It has been decided to implement the CMake cross-compiling
+      technique of toolchain files. We will use a linux platform with the mingw
+      compiler stack for testing. Only the C language is fully supported, and
+      the error tests are skipped. The C++ language works for static but shared
+      builds has a shared library issue with the mingw Standard Exception Handling
+      library, which is not available on Windows. Fortran has a common cross-compile
+      problem with the fortran configure tests.
+
+      (ADB - 2019/07/12, HDFFV-10845, HDFFV-10595)
+
+    - Windows PDB files are installed incorrectly
+
+      For static builds, the PDB files for windows should be installed next
+      to the static libraries in the lib folder. Also the debug versions of
+      libraries and PDB files are now correctly built using the default
+      CMAKE_DEBUG_POSTFIX setting.
+
+      (ADB - 2019/07/09, HDFFV-10581)
+
+    - Add option to build only shared libs
+
+      A request was made to prevent building static libraries and only build
+      shared.  A new option was added to CMake, ONLY_SHARED_LIBS, which will
+      skip building static libraries. Certain utility functions will build with
+      static libs but are not published. Tests are adjusted to use the correct
+      libraries depending on SHARED/STATIC settings.
+
+      (ADB - 2019/06/12, HDFFV-10805)
+
+    - Add options to enable or disable building tools and tests
+
+      Configure options --enable-tests and --enable-tools were added for
+      autotools configure.  These options are enabled by default, and can be
+      disabled with either --disable-tests (or tools) or --enable-tests=no
+      (or --enable-tools=no).  Build time is reduced ~20% when tools are
+      disabled, 35% when tests are disabled, 45% when both are disabled.
+      Reenabling them after the initial build requires running configure
+      again with the option(s) enabled.
+
+      (LRK - 2019/06/12, HDFFV-9976)
+
+    - Change tools test that test the error stack
+
+      There are some use cases which can cause the error stack of tools to be
+      different then the expected output. These tests now use grepTest.cmake,
+      this was changed to allow the error file to be searched for an expected string.
+
+      (ADB - 2019/04/15, HDFFV-10741)
+
+    - Keep stderr and stdout separate in tests
+
+      Changed test handling of output capture. Tests now keep the stderr
+      output separate from the stdout output. It is up to the test to decide
+      which output to check against a reference. Also added the option
+      to grep for a string in either output.
+
+      (ADB - 2018/12/12, HDFFV-10632)
+
+    - Add toolchain and cross-compile support
+
+      Added info on using a toolchain file to INSTALL_CMAKE.txt. A
+      toolchain file is also used in cross-compiling, which requires
+      CMAKE_CROSSCOMPILING_EMULATOR to be set. To help with cross-compiling
+      the fortran configure process, the HDF5UseFortran.cmake file macros
+      were improved. Fixed a Fortran configure file issue that incorrectly
+      used #cmakedefine instead of #define.
+
+      (ADB - 2018/10/04, HDFFV-10594)
+
+    - Add warning flags for Intel compilers
+
+      Identified Intel compiler specific warnings flags that should be used
+      instead of GNU flags.
+
+      (ADB - 2018/10/04, TRILABS-21)
+
+    - Add default rpath to targets
+
+      Default rpaths should be set in shared executables and
+      libraries to allow the use of loading dependent libraries
+      without requiring LD_LIBRARY_PATH to be set. The default
+      path should be relative using @rpath on osx and $ORIGIN
+      on linux. Windows is not affected.
+
+      (ADB - 2018/09/26, HDFFV-10594)
+
+    - Add missing USE_110_API_DEFAULT option.
+
+      Option USE_110_API_DEFAULT sets the default version of
+      versioned APIs. The bin/makevers perl script did not set
+      the maxidx variable correctly when the 1.10 branch was
+      created. This caused the versioning process to always use
+      the latest version of any API.
+
+      (ADB - 2018/08/17, HDFFV-10552)
+
+    - Added configuration checks for the following MPI functions:
+
+      MPI_Mprobe - Used for the Parallel Compression feature
+      MPI_Imrecv - Used for the Parallel Compression feature
+
+      MPI_Get_elements_x - Used for the "big Parallel I/O" feature
+      MPI_Type_size_x - Used for the "big Parallel I/O" feature
+
+      (JTH - 2018/08/02, HDFFV-10512)
+
+    - Added section to the libhdf5.settings file to indicate
+      the status of the Parallel Compression and "big Parallel I/O"
+      features.
+
+      (JTH - 2018/08/02, HDFFV-10512)
+
+    - Add option to execute swmr shell scripts from CMake.
+
+      Option TEST_SHELL_SCRIPTS redirects processing into a
+      separate ShellTests.cmake file for UNIX types. The tests
+      execute the shell scripts if a SH program is found.
+
+      (ADB - 2018/07/16)
+
+
+    Library:
+    --------
+    - Add new H5R_ref_t type for object, dataset region and _attribute_
+      references. This new type will deprecate the current hobj_ref_t
+      and hdset_reg_ref_t types for references. Added H5T_REF datatype
+      to read and write new reference types. As opposed to previous
+      reference types, reference creation no longer modifies existing
+      files. New reference types also now support references to external
+      files.
+
+      (JS - 2019/10/08)
+
+    - Add S3 and HDFS VFDs to HDF5 maintenance
+
+      Fix windows requirements and java tests. Windows requires CMake 3.13.
+            Install openssl library (with dev files);
+            from "Shining Light Productions". msi package preferred.
+
+            PATH should have been updated with the installation dir.
+            set ENV variable OPENSSL_ROOT_DIR to the installation dir.
+            set ENV variable OPENSSL_CONF to the cfg file, likely %OPENSSL_ROOT_DIR%\bin\openssl.cfg
+            Install libcurl library (with dev files);
+            download the latest released version using git: https://github.com/curl/curl.git
+
+            Open a Visual Studio Command prompt
+            change to the libcurl root folder
+            run the "buildconf.bat" batch file
+            change to the winbuild directory
+            nmake /f Makefile.vc mode=dll MACHINE=x64
+            copy libcurl-vc-x64-release-dll-ipv6-sspi-winssl dir to C:\curl (installation dir)
+            set ENV variable CURL_ROOT to C:\curl (installation dir)
+            update PATH ENV variable to %CURL_ROOT%\bin (installation bin dir).
+            the aws credentials file should be in %USERPROFILE%\.aws folder
+            set the ENV variable "HDF5_ROS3_TEST_BUCKET_URL=https://s3.us-east-2.amazonaws.com/hdf5ros3"
+
+      (ADB - 2019/09/12, HDFFV-10854)
+
+    - Added new chunk query functions
+
+      The following public functions were added to discover information about
+      the chunks in an HDF5 file.
+        herr_t H5Dget_num_chunks(dset_id, fspace_id, *nchunks)
+        herr_t H5Dget_chunk_info_by_coord(dset_id, *coord, *filter_mask, *addr, *size)
+        herr_t H5Dget_chunk_info(dset_id, fspace_id, index, *coord, *filter_mask, *addr, *size)
+
+      (BMR - 2019/06/11, HDFFV-10677)
+
+    - Improved the performance of virtual dataset I/O
+
+      Refactored the internal dataspace routines used by the virtual dataset
+      code to improve performance, especially when one of the selections
+      involved is very long and non-contiguous.
+
+      (NAF - 2019/05/31, HDFFV-10693)
+
+    - Added the ability to open files with UTF-8 file names on Windows.
+
+      The POSIX open(2) API call on Windows is limited to ASCII
+      file names. The library has been updated to convert incoming file
+      names to UTF-16 (via MultiByteToWideChar(CP_UTF8, ...) and use
+      _wopen() instead.
+
+     (DER - 2019/03/15, HDFFV-2714, HDFFV-3914, HDFFV-3895, HDFFV-8237, HDFFV-10413, HDFFV-10691)
+
+    - Add new API H5M for map objects.  Currently not supported by native
+      library, can be supported by VOL connectors.
+
+      (NAF - 2019/03/01)
+
+    - Remove H5I_REFERENCE from the library
+
+      This ID class was never used by the library and has been removed.
+
+      (DER - 2018/12/08, HDFFV-10252)
+
+    - Allow pre-generated H5Tinit.c and H5make_libsettings.c to be used.
+
+      Rather than always running H5detect and generating H5Tinit.c and
+      H5make_libsettings.c, supply a location for those files.
+
+      (ADB - 2018/09/18, HDFFV-10332)
+
+
+    Parallel Library:
+    -----------------
+    - Changed the default behavior in parallel when reading the same dataset in its entirely
+      (i.e. H5S_ALL dataset selection) which is being read by all the processes collectively.
+      The dataset mush be contiguous, less than 2GB, and of an atomic datatype.
+      The new behavior is the HDF5 library will use an MPI_Bcast to pass the data read from
+      the disk by the root process to the remain processes in the MPI communicator associated
+      with the HDF5 file.
+
+      (MSB - 2019/01/02, HDFFV-10652)
+
+    Fortran Library:
+    ----------------
+    - Added new Fortran derived type, c_h5o_info_t, which is interoperable with
+      C's h5o_info_t. This is needed for callback functions which
+      pass C's h5o_info_t data type definition.
+
+      (MSB, 2019/01/08, HDFFV-10443)
+
+    - Added new Fortran API, H5gmtime, which converts (C) 'time_t' structure
+      to Fortran DATE AND TIME storage format.
+
+      (MSB, 2019/01/08, HDFFV-10443)
+
+    - Added new Fortran 'fields' optional parameter to: h5ovisit_f, h5oget_info_by_name_f,
+      h5oget_info, h5oget_info_by_idx and h5ovisit_by_name_f.
+
+      (MSB, 2019/01/08, HDFFV-10443)
+
+    C++ Library:
+    ------------
+    - Added new wrappers for H5Pset/get_create_intermediate_group()
+        LinkCreatPropList::setCreateIntermediateGroup()
+        LinkCreatPropList::getCreateIntermediateGroup()
+
+      (BMR - 2019/04/22, HDFFV-10622)
+
+    - Added new wrapper for H5Ovisit2()
+          H5Object::visit()
+
+      (BMR - 2019/02/14, HDFFV-10532)
+
+
+    Java Library:
+    ----------------
+    - Fix a failure in JUnit-TestH5P on 32-bit architectures
+
+      (JTH - 2019/04/30)
+
+    - Duplicate the data read/write functions of Datasets for Attributes.
+
+      Region references could not be displayed for attributes as they could
+      for datasets. Datasets had overloaded read and write functions for different
+      datatypes that were not available for attributes. After adding similar
+      functions, attribute region references work normally.
+
+      (ADB - 2018/12/12, HDFVIEW-4)
+
+    - Removed H5I_REFERENCE from the Java wrappers
+
+      This ID class was never used by the library and has been removed
+      from the Java wrappers.
+
+      (DER - 2018/12/08, HDFFV-10252)
+
+
+    Tools:
+    ------
+    - h5repack was fixed to repack datasets with external storage
+      to other types of storage.
+
+      New test added to repack files and verify the correct data using h5diff.

+
+Bug Fixes since HDF5-1.10.3 release
+==================================
+
+    Library
+    -------
+    - Improved performance when creating a large number of small datasets by
+      retrieving default property values from the API context instead of doing
+      skip list searches.
+
+      (CJH - 2019/12/10, HDFFV-10658)
+
+    - Fixed user-created data access properties not existing in the property list
+      returned by H5Dget_access_plist. Thanks to Steven Varga for submitting a
+      reproducer and a patch.
+
+      (CJH - 2019/12/9, HDFFV-10934)
+
+    - Fixed the iteration error in test_versionbounds() in test/dtypes.c
+
+      The test was supposed to loop through all valid combinations of
+      low and high bounds in the array versions[], but they were set to
+      H5F_LIBVER_EARLIEST always without changing.
+
+      The problem was fixed by indexing low and high into the array versions[].
+
+      (VC - 2019/09/30)
+
+    - Fixed the slowness of regular hyperslab selection in a chunked dataset
+
+      It was reported that the selection of every 10th element from a 20G
+      chunked dataset was extremely slow and sometimes could hang the system.
+      The problem was due to the iteration and the building of the span tree
+      for all the selected elements in file space.
+
+      As the selected elements are going to a 1-d contiguous single block
+      memory space, the problem was fixed by building regular hyperslab selections
+      in memory space for the selected elements in file space.
+
+      (VC - 2019/09/26, HDFFV-10585)
+
+    - Fixed a bug caused by bad tag value when condensing object header
+      messages
+
+      There was an assertion failure when moving meessages from running a
+      user test program with library release hdf5.1.10.4. It was because
+      the tag value (object header's address) was not set up when entering
+      the library routine H5O__chunk_update_idx(), which will eventually
+      verifies the metadata tag value when protecting the object header.
+
+      The problem was fixed by replacing FUNC_ENTER_PACKAGE in H5O__chunk_update_idx()
+      with FUNC_ENTER_PACKAGE_TAG(oh->cache_info.addr) to set up the metadata tag.
+
+      (VC - 2019/08/23, HDFFV-10873)
+
+    - Fixed the test failure from test_metadata_read_retry_info() in
+      test/swmr.c
+
+      The test failure is due to the incorrect number of bins returned for
+      retry info (info.nbins).  The # of bins expected for 101 read attempts
+      is 3 instead of 2.  The routine H5F_set_retries() in src/H5Fint.c
+      calculates the # of bins by first obtaining the log10 value for
+      (read attempts - 1).  For PGI/19, the log10 value for 100 read attempts
+      is 1.9999999999999998 instead of 2.00000.  When casting the log10 value
+      to unsigned later on, the decimal part is chopped off causing the test
+      failure.
+
+      This was fixed by obtaining the rounded integer value (HDceil) for the
+      log10 value of read attempts first before casting the result to unsigned.
+
+      (VC - 2019/8/14, HDFFV-10813)
+
+    - Fixed an issue where creating a file with non-default file space info
+      together with library high bound setting to H5F_LIBVER_V18.
+
+      When setting non-default file space info in fcpl via
+      H5Pset_file_space_strategy() and then creating a file with
+      both high and low library bounds set to
+      H5F_LIBVER_V18 in fapl, the library succeeds in creating the file.
+      File creation should fail because the feature of setting non-default
+      file space info does not exist in library release 1.8 or earlier.
+
+      This was fixed by setting and checking the proper version in the
+      file space info message based on the library low and high bounds
+      when creating and opening the HDF5 file.
+
+      (VC - 2019/6/25, HDFFV-10808)
+
+    - When iterating over an old-style group (i.e., when not using the latest
+      file format) of size 0, a NULL pointer representing the empty links
+      table would be sent to qsort(3) for sorting, which is undefined behavior.
+
+      Iterating over an empty group is explicitly tested in the links test.
+      This has not caused any failures to date and was flagged by gcc's
+      -fsanitize=undefined.
+
+      The library no longer attempts to sort an empty array.
+
+      (DER - 2019/06/18, HDFFV-10829)
+
+    - Fixed an issue where copying a version 1.8 dataset between files using
+      H5Ocopy fails due to an incompatible fill version
+
+      When using the HDF5 1.10.x H5Ocopy() API call to copy a version 1.8
+      dataset to a file created with both high and low library bounds set to
+      H5F_LIBVER_V18, the H5Ocopy() call will fail with the error stack indicating
+      that the fill value version is out of bounds.
+
+      This was fixed by changing the fill value message version to H5O_FILL_VERSION_3
+      (from H5O_FILL_VERSION_2) for H5F_LIBVER_V18.
+
+      (VC - 2019/6/14, HDFFV-10800)
+
+    - Some oversights in the index iterating area of the library caused
+      a callback function to continue iterating even though it's supposed
+      to stop.
+
+      Added the returned value check to the for loop's conditions in
+      H5EA_iterate(), H5FA_iterate(), and H5D__none_idx_iterate().  The
+      iteration now stops when it should.
+
+      (BMR - 2019/06/11, HDFFV-10661)
+
+    - Fixed a bug that would cause an error or cause fill values to be
+      incorrectly read from a chunked dataset using the "single chunk" index if
+      the data was held in cache and there was no data on disk.
+
+      (NAF - 2019/03/06)
+
+    - Fixed a bug that could cause an error or cause fill values to be
+      incorrectly read from a dataset that was written to using H5Dwrite_chunk
+      if the dataset was not closed after writing.
+
+      (NAF - 2019/03/06, HDFFV-10716)
+
+    - Fixed memory leak in scale offset filter
+
+      In a special case where the MinBits is the same as the number of bits in
+      the datatype's precision, the filter's data buffer was not freed, causing
+      the memory usage to grow. In general the buffer was freed correctly.  The
+      Minbits are the minimal number of bits to store the data values.  Please
+      see the reference manual for H5Pset_scaleoffset for the detail.
+
+      (RL - 2019/3/4, HDFFV-10705)
+
+    - Fix hangs with collective metadata reads during chunked dataset I/O
+
+      In the parallel library, it was discovered that when a particular
+      sequence of operations following a pattern of:
+
+      "write to chunked dataset" -> "flush file" -> "read from dataset"
+
+      occurred with collective metadata reads enabled, hangs could be
+      observed due to certain MPI ranks not participating in the collective
+      metadata reads.
+
+      To fix the issue, collective metadata reads are now disabled during
+      chunked dataset raw data I/O.
+
+      (JTH - 2019/02/11, HDFFV-10563, HDFFV-10688)
+
+    - Performance issue when closing an object
+
+      The slow down is due to the search of the "tag_list" to find
+      out the "corked" status of an object and "uncork" it if so.
+
+      Improve porformance by skipping the search of the "tag_list"
+      if there are no "corked" objects when closing an object.
+
+      (VC - 2019/2/6)
+
+    - Fixed a potential invalid memory access and failure that could occur when
+      decoding an unknown object header message (from a future version of the
+      library).
+
+      (NAF - 2019/01/07)
+
+    - Deleting attributes in dense storage
+
+      The library aborts with "infinite loop closing library" after
+      attributes in dense storage are created and then deleted.
+
+      When deleting the attribute nodes from the name index v2 B-tree,
+      if an attribute is found in the intermediate B-tree nodes,
+      which may be merged/redistributed in the process, we need to
+      free the dynamically allocated spaces for the intermediate
+      decoded attribute.
+
+      (VC - 2018/12/26, HDFFV-10659)
+
+    - Allow H5detect and H5make_libsettings to take a file as an argument.
+
+      Rather than only writing to stdout, add a command argument to name
+      the file that H5detect and H5make_libsettings will use for output.
+      Without an argument, stdout is still used, so backwards compatibility
+      is maintained.
+
+      (ADB - 2018/09/05, HDFFV-9059)
+
+    - A bug was discovered in the parallel library where an application
+      would hang if a collective read/write of a chunked dataset occurred
+      when collective metadata reads were enabled and some of the ranks
+      had no selection in the dataset's dataspace. The ranks which had no
+      selection in the dataset's dataspace called H5D__chunk_addrmap() to
+      retrieve the lowest chunk address in the dataset. This is because we
+      require reads/writes to be performed in strictly non-decreasing order
+      of chunk address in the file.
+
+      When the chunk index used was a version 1 or 2 B-tree, these
+      non-participating ranks would issue a collective MPI_Bcast() call
+      that the participating ranks would not issue, causing the hang. Since
+      the non-participating ranks are not actually reading/writing anything,
+      the H5D__chunk_addrmap() call can be safely removed and the address used
+      for the read/write can be set to an arbitrary number (0 was chosen).
+
+      (JTH - 2018/08/25, HDFFV-10501)
+
+    - fcntl(2)-based file locking incorrectly passed the lock argument struct
+      instead of a pointer to the struct, causing errors on systems where
+      flock(2) is not available.
+
+      File locking is used when files are opened to enforce SWMR semantics. A
+      lock operation takes place on all file opens unless the
+      HDF5_USE_FILE_LOCKING environment variable is set to the string "FALSE".
+      flock(2) is preferentially used, with fcntl(2) locks as a backup if
+      flock(2) is unavailable on a system (if neither is available, the lock
+      operation fails). On these systems, the file lock will often fail, which
+      causes HDF5 to not open the file and report an error.
+
+      This bug only affects POSIX systems. Win32 builds on Windows use a no-op
+      locking call which always succeeds. Systems which exhibit this bug will
+      have H5_HAVE_FCNTL defined but not H5_HAVE_FLOCK in the configure output.
+
+      This bug affects HDF5 1.10.0 through 1.10.5.
+
+      fcntl(2)-based file locking now correctly passes the struct pointer.
+
+      (DER - 2019/08/27, HDFFV-10892)
+
+
+    Java Library:
+    ----------------
+    - JNI native library dependencies
+
+      The build for the hdf5_java native library used the wrong
+      hdf5 target library for CMake builds. Correcting the hdf5_java
+      library to build with the shared hdf5 library required testing
+      paths to change also.
+
+      (ADB - 2018/08/31, HDFFV-10568)
+     - Java iterator callbacks
+
+      Change global callback object to a small stack structure in order
+      to fix a runtime crash. This crash was discovered when iterating
+      through a file with nested group members. The global variable
+      visit_callback is overwritten when recursion starts. When recursion
+      completes, visit_callback will be pointing to the wrong callback method.
+
+      (ADB - 2018/08/15, HDFFV-10536)
+
+    - Java HDFLibraryException class
+
+      Change parent class from Exception to RuntimeException.
+
+      (ADB - 2018/07/30, HDFFV-10534)
+
+    - JNI Read and Write
+
+      Refactored variable-length functions, H5DreadVL and H5AreadVL,
+      to correct dataset and attribute reads. New write functions,
+      H5DwriteVL and H5AwriteVL, are under construction.
+
+      (ADB - 2018/06/02, HDFFV-10519)
+
+
+    Configuration
+    -------------
+    - Correct option for default API version
+
+      CMake options for default API version are not mutually exclusive.
+      Change the multiple BOOL options to a single STRING option with the
+      strings; v16, v18, v110, v112.
+
+      (ADB - 2019/08/12, HDFFV-10879)
+
+
+    Fortran
+    --------
+    - Added symbolic links libhdf5_hl_fortran.so to libhdf5hl_fortran.so and
+      libhdf5_hl_fortran.a to libhdf5hl_fortran.a in hdf5/lib directory for
+      autotools installs.  These were added to match the name of the files
+      installed by cmake and the general pattern of hl lib files.  We will
+      change the names of the installed lib files to the matching name in
+      the next major release.
+
+      (LRK - 2019/01/04, HDFFV-10596)
+
+    - Made Fortran specific subroutines PRIVATE in generic procedures.
+
+      Effected generic procedures were functions in H5A, H5D, H5P, H5R and H5T.
+
+      (MSB, 2018/12/04, HDFFV-10511)
+
+    - Fixed issue with Fortran not returning h5o_info_t field values
+      meta_size%attr%index_size and  meta_size%attr%heap_size.

+
+Bug Fixes since HDF5-1.10.2 release
+==================================
+
+    Library
+    -------
+    - Java HDF5LibraryException class
+
+      The error minor and major values would be lost after the
+      constructor executed.
+
+      Created two local class variables to hold the values obtained during
+      execution of the constructor. Refactored the class functions to retrieve
+      the class values rather then calling the native functions.
+      The native functions were renamed and called only during execution
+      of the constructor.
+      Added error checking to calling class constructors in JNI classes.
+
+      (ADB - 2018/08/06, HDFFV-10544)
+
+    - Added checks of the defined MPI_VERSION to guard against usage of
+      MPI-3 functions in the Parallel Compression and "big Parallel I/O"
+      features when HDF5 is built with MPI-2. Previously, the configure
+      step would pass but the build itself would fail when it could not
+      locate the MPI-3 functions used.
+
+      As a result of these new checks, HDF5 can again be built with MPI-2,
+      but the Parallel Compression feature will be disabled as it relies
+      on the MPI-3 functions used.

+
+    - A bug was discovered in the parallel library which caused partial
+      parallel reads of filtered datasets to return incorrect data. The
+      library used the incorrect dataspace for each chunk read, causing
+      the selection used in each chunk to be wrong.
+
+      The bug was not caught during testing because all of the current
+      tests which do parallel reads of filtered data read all of the data
+      using an H5S_ALL selection. Several tests were added which exercise
+      partial parallel reads.
+
+      (JTH - 2018/07/16, HDFFV-10467)
+
+    - A bug was discovered in the parallel library which caused parallel
+      writes of filtered datasets to trigger an assertion failure in the
+      file free space manager.
+
+      This occurred when the filter used caused chunks to repeatedly shrink
+      and grow over the course of several dataset writes. The previous chunk
+      information, such as the size of the chunk and the offset in the file,
+      was being cached and not updated after each write, causing the next write
+      to the chunk to retrieve the incorrect cached information and run into
+      issues when reallocating space in the file for the chunk.
+
+      (JTH - 2018/07/16, HDFFV-10509)
+
+    - A bug was discovered in the parallel library which caused the
+      H5D__mpio_array_gatherv() function to allocate too much memory.
+
+      When the function is called with the 'allgather' parameter set
+      to a non-true value, the function will receive data from all MPI
+      ranks and gather it to the single rank specied by the 'root'
+      parameter. However, the bug in the function caused memory for
+      the received data to be allocated on all MPI ranks, not just the
+      singular rank specified as the receiver. In some circumstances,
+      this would cause an application to fail due to the large amounts
+      of memory being allocated.

+
+    - Error checks in h5stat and when decoding messages
+
+      h5stat exited with seg fault/core dumped when
+      errors are encountered in the internal library.
+
+      Add error checks and --enable-error-stack option to h5stat.

+      Fixing this problem would involve updating the publicly visible
+      H5T_conv_t function pointer typedef and versioning the API calls
+      which use it. We normally only modify the public API during
+      major releases, so this bug will not be fixed at this time.

+
+    - Inappropriate linking with deprecated MPI C++ libraries
+
+      HDF5 does not define *_SKIP_MPICXX in the public headers, so applications
+      can inadvertently wind up linking to the deprecated MPI C++ wrappers.
+
+      MPICH_SKIP_MPICXX and OMPI_SKIP_MPICXX have both been defined in H5public.h
+      so this should no longer be an issue. HDF5 makes no use of the deprecated
+      MPI C++ wrappers.

+
+    Configuration
+    -------------
+    - Applied patches to address Cywin build issues
+
+      There were three issues for Cygwin builds:
+      - Shared libs were not built.
+      - The -std=c99 flag caused a SIG_SETMASK undeclared error.
+      - Undefined errors when buildbing test shared libraries.
+
+      Patches to address these issues were received and incorporated in this version.
+
+      (LRK - 2018/07/18, HDFFV-10475)
+
+    - Moved the location of gcc attribute.
+
+      The gcc attribute(no_sanitize), named as the macro HDF_NO_UBSAN,
+      was located after the function name. Builds with GCC 7 did not
+      indicate any problem, but GCC 8 issued errors. Moved the
+      attribute before the function name, as required.
+
+      (ADB - 2018/05/22, HDFFV-10473)
+
+    - Reworked java test suite into individual JUnit tests.
+
+      Testing the whole suite of java unit tests in a single JUnit run
+      made it difficult to determine actual failures when tests would fail.
+      Running each file set of tests individually, allows individual failures
+      to be diagnosed easier. A side benefit is that tests for optional components
+      of the library can be disabled if not configured.
+
+      (ADB - 2018/05/16, HDFFV-9739)
+
+    - Converted CMake global commands ADD_DEFINITIONS and INCLUDE_DIRECTORIES
+      to use target_* type commands. This change modernizes the CMake usage
+      in the HDF5 library.
+
+      In addition, there is the intention to convert to generator expressions,
+      where possible. The exception is Fortran FLAGS on Windows Visual Studio.
+      The HDF macros TARGET_C_PROPERTIES and TARGET_FORTRAN_PROPERTIES have
+      been removed with this change in usage.
+
+      The additional language (C++ and Fortran) checks have also been localized
+      to only be checked when that language is enabled.

+
+    Testing
+    -------
+    - The dt_arith test failed on IBM Power8 and Power9 machines when testing
+      conversions from or to long double types, especially when special values
+      such as infinity or NAN were involved.  In some cases the results differed
+      by extremely small amounts from those on other machines, while some other
+      tests resulted in segmentation faults.  These conversion tests with long
+      double types have been disabled for ppc64 machines until the problems are
+      better understood and can be properly addressed.

+Known Problems
+==============
+    CMake files do not behave correctly with paths containing spaces.
+    Do not use spaces in paths because the required escaping for handling spaces
+    results in very complex and fragile build files.
+    ADB - 2019/05/07
+
+    At present, metadata cache images may not be generated by parallel
+    applications.  Parallel applications can read files with metadata cache
+    images, but since this is a collective operation, a deadlock is possible
+    if one or more processes do not participate.
+

+
+
+CMake vs. Autotools installations
+=================================
+While both build systems produce similar results, there are differences.
+Each system produces the same set of folders on linux (only CMake works
+on standard Windows); bin, include, lib and share. Autotools places the
+COPYING and RELEASE.txt file in the root folder, CMake places them in
+the share folder.
+
+The bin folder contains the tools and the build scripts. Additionally, CMake
+creates dynamic versions of the tools with the suffix "-shared". Autotools
+installs one set of tools depending on the "--enable-shared" configuration
+option.
+  build scripts
+  -------------
+  Autotools: h5c++, h5cc, h5fc
+  CMake: h5c++, h5cc, h5hlc++, h5hlcc
+
+The include folder holds the header files and the fortran mod files. CMake
+places the fortran mod files into separate shared and static subfolders,
+while Autotools places one set of mod files into the include folder. Because
+CMake produces a tools library, the header files for tools will appear in
+the include folder.
+
+The lib folder contains the library files, and CMake adds the pkgconfig
+subfolder with the hdf5*.pc files used by the bin/build scripts created by
+the CMake build. CMake separates the C interface code from the fortran code by
+creating C-stub libraries for each Fortran library. In addition, only CMake
+installs the tools library. The names of the szip libraries are different
+between the build systems.
+
+The share folder will have the most differences because CMake builds include
+a number of CMake specific files for support of CMake's find_package and support
+for the HDF5 Examples CMake project.

+New Features
+============
+
+    Configuration:
+    -------------
+    - Added test script for file size compare
+
+        If CMake minimum version is at least 3.14, the fileCompareTest.cmake
+        script will compare file sizes.
+
+        (ADB - 2020/02/24, HDFFV-11036)
+
+    - Update CMake minimum version to 3.12
+
+        Updated CMake minimum version to 3.12 and added version checks
+        for Windows features.
+
+        (ADB - 2020/02/05, TRILABS-142)
+
+    - Fixed CMake include properties for Fortran libraries
+
+        Corrected the library properties for Fortran to use the
+        correct path for the Fortran module files.
+
+        (ADB - 2020/02/04, HDFFV-11012)
+
+    - Added common warnings files for gnu and intel
+
+        Added warnings files to use one common set of flags
+        during configure for both autotools and CMake build
+        systems. The initial implementation only affects a
+        general set of flags for gnu and intel compilers.
+
+        (ADB - 2020/01/17)
+
+    - Added new options to CMake for control of testing
+
+        Added CMake options (default ON);
+          HDF5_TEST_SERIAL AND/OR HDF5_TEST_PARALLEL
+          combined with:
+            HDF5_TEST_TOOLS
+            HDF5_TEST_EXAMPLES
+            HDF5_TEST_SWMR
+            HDF5_TEST_FORTRAN

+
+        Added CMake code and files to execute the Clang sanitizers if
+        HDF5_ENABLE_SANITIZERS is enabled and the USE_SANITIZER option
+        is set to one of the following:
+          Address
+          Memory
+          MemoryWithOrigins
+          Undefined
+          Thread
+          Leak
+          'Address;Undefined'
+
+        (ADB - 2019/12/12, TRILAB-135)
+
+    - Update CMake for VS2019 support
+
+        CMake added support for VS2019 in version 3.15. Changes to the CMake
+        generator setting required changes to scripts. Also updated version
+        references in CMake files as necessary.
+
+        (ADB - 2019/11/18, HDFFV-10962)
+
+
+    Library:
+    --------
+    - Refactored public exposure of haddr_t type in favor of "object tokens"
+
+        To better accommodate HDF5 VOL connectors where "object addresses in a file"
+        may not make much sense, the following changes were made to the library:
+
+        * Introduced new H5O_token_t "object token" type, which represents a
+            unique and permanent identifier for referencing an HDF5 object within
+            a container; these "object tokens" are meant to replace object addresses.
+            Along with the new type, a new H5Oopen_by_token API call was introduced
+            to open an object by a token, similar to how object addresses were
+            previously used with H5Oopen_by_addr.
+
+        * Introduced new H5Lget_info2, H5Lget_info_by_idx2, H5Literate2, H5Literate_by_name2,
+            H5Lvisit2 and H5Lvisit_by_name2 API calls, along with their associated H5L_info2_t
+            struct and H5L_iterate2_t callback function, which work with the newly-introduced
+            object tokens, instead of object addresses. The original functions have been
+            renamed to version 1 functions and are deprecated in favor of the new version 2
+            functions. The H5L_info_t and H5L_iterate_t types have been renamed to version 1
+            types and are now deprecated in favor of their version 2 counterparts. For each of
+            the functions and types, compatibility macros take place of the original symbols.
+
+        * Introduced new H5Oget_info3, H5Oget_info_by_name3, H5Oget_info_by_idx3,
+            H5Ovisit3 and H5Ovisit_by_name3 API calls, along with their associated H5O_info2_t
+            struct and H5O_iterate2_t callback function, which work with the newly-introduced
+            object tokens, instead of object addresses. The version 2 functions are now
+            deprecated in favor of the version 3 functions. The H5O_info_t and H5O_iterate_t
+            types have been renamed to version 1 types and are now deprecated in favor of their
+            version 2 counterparts. For each, compatibility macros take place of the original
+            symbols.
+
+        * Introduced new H5Oget_native_info, H5Oget_native_info_by_name and
+            H5Oget_native_info_by_idx API calls, along with their associated H5O_native_info_t
+            struct, which are used to retrieve the native HDF5 file format-specific information
+            about an object. This information (such as object header info and B-tree/heap info)
+            has been removed from the new H5O_info2_t struct so that the more generic
+            H5Oget_info(_by_name/_by_idx)3 routines will not try to retrieve it for non-native
+            VOL connectors.
+
+        * Added new H5Otoken_cmp, H5Otoken_to_str and H5Otoken_from_str routines to compare
+            two object tokens, convert an object token into a nicely-readable string format and
+            to convert an object token string back into a real object token, respectively.
+
+        (DER, QAK, JTH - 2020/01/16)
+
+    - Virtual Object Layer (VOL)
+
+        In this major HDF5 release we introduce HDF5 Virtual Object Layer (VOL).
+        VOL is an abstraction layer within the HDF5 library that enables different
+        methods for accessing data and objects that conform to the HDF5 data model.
+        The VOL layer intercepts all HDF5 API calls that potentially modify data
+        on disk and forwards those calls to a plugin "object driver". The data on
+        disk can be a different format than the HDF5 format. For more information
+        about VOL we refer the reader to the following documents (under review):
+
+          VOL HDF5 APIs
+          https://portal.hdfgroup.org/display/HDF5/Virtual+Object++Layer
+
+          VOL Documentation
+          https://bitbucket.hdfgroup.org/projects/HDFFV/repos/hdf5doc/browse/RFCs/HDF5/VOL
+
+          Repository with VOL plugins
+          https://bitbucket.hdfgroup.org/projects/HDF5VOL
+
+    - Enhancements to HDF5 References
+
+        HDF5 references were extended to support attributes, and object and dataset
+        selections that reside in another HDF5 file. For more information including
+        a list of new APIs, see
+
+          https://portal.hdfgroup.org/display/HDF5/Update+to+References
+
+    - Add new public function H5Sselect_adjust.
+
+        This function shifts a dataspace selection by a specified logical offset
+        within the dataspace extent.  This can be useful for VOL developers to
+        implement chunked datasets.
+
+        (NAF - 2019/11/18)
+
+    - Add new public function H5Sselect_project_intersection.
+
+        This function computes the intersection between two dataspace selections
+        and projects that intersection into a third selection.  This can be useful
+        for VOL developers to implement chunked or virtual datasets.
+
+        (NAF - 2019/11/13, ID-148)
+
+    - Add new public function H5VLget_file_type.
+
+        This function returns a datatype equivalent to the supplied datatype but
+        with the location set to be in the file.  This datatype can then be used
+        with H5Tconvert to convert data between file and in-memory representation.
+        This funcition is intended for use only by VOL connector developers.
+
+        (NAF - 2019/11/08, ID-127)
+
+    - New S3 and HDFS Virtual File Drivers (VFDs)
+
+        This release has two new VFDs. The S3 VFD allows accessing HDF5 files on
+        AWS S3 buckets. HDFS VFD allows accessing HDF5 files stored on Apache HDFS.
+        See https://portal.hdfgroup.org/display/HDF5/Virtual+File+Drivers+-+S3+and+HDFS
+        for information on enabling those drivers and using those APIs.
+
+        Below are specific instructions for enabling S3 VFD on Windows:
+
+        Fix windows requirements and java tests. Windows requires CMake 3.13.
+          - Install openssl library (with dev files);
+                from "Shining Light Productions". msi package preferred.
+          - PATH should have been updated with the installation dir.
+          - set ENV variable OPENSSL_ROOT_DIR to the installation dir.
+          - set ENV variable OPENSSL_CONF to the cfg file, likely %OPENSSL_ROOT_DIR%\bin\openssl.cfg
+          - Install libcurl library (with dev files);
+          - download the latest released version using git: https://github.com/curl/curl.git
+          - Open a Visual Studio Command prompt
+          - change to the libcurl root folder
+          - run the "buildconf.bat" batch file
+          - change to the winbuild directory
+          - nmake /f Makefile.vc mode=dll MACHINE=x64
+          - copy libcurl-vc-x64-release-dll-ipv6-sspi-winssl dir to C:\curl (installation dir)
+          - set ENV variable CURL_ROOT to C:\curl (installation dir)
+          - update PATH ENV variable to %CURL_ROOT%\bin (installation bin dir).
+          - the aws credentials file should be in %USERPROFILE%\.aws folder
+          - set the ENV variable HDF5_ROS3_TEST_BUCKET_URL to the s3 url for the
+                s3 bucket containing the HDF5 files to be accessed.
+
+    FORTRAN Library:
+    ----------------
+    - Added new Fortran parameters:
+
+        H5F_LIBVER_ERROR_F
+        H5F_LIBVER_NBOUNDS_F
+        H5F_LIBVER_V18_F
+        H5F_LIBVER_V110_F
+        H5F_LIBVER_V112_F
+
+    - Added new Fortran API: h5pget_libver_bounds_f
+
+        (MSB - 2020/02/11, HDFFV-11018)
+
+    Java Library:
+    ----------------
+    - Added ability to test java library with VOLs.
+
+        Created new CMake script that combines the java and vol test scripts.
+
+        (ADB - 2020/02/03, HDFFV-10996)
+
+    - Tests fail for non-English locale.
+
+        In the JUnit tests with a non-English locale, only the part before
+        the decimal comma is replaced by XXXX and this leads to a comparison
+        error. Changed the regex for the Time substitution.
+
+        (ADB - 2020/01/09, HDFFV-10995)
+
+
+    Tools:
+    ------
+    - h5diff was updated to use the new reference APIs.
+
+        h5diff uses the new reference APIs to compare references.
+        Attribute references can also be compared.
+
+        (ADB - 2019/12/19, HDFFV-10980)
+
+    - h5dump and h5ls were updated to use the new reference APIs.
+
+        The tools library now use the new reference APIs to inspect a
+        file. Also the DDL spec was updated to reflect the format
+        changes produced with the new APIs. The export API and support
+        functions in the JNI were updated to match.
+
+
+    Other improvements and changes:
+
+    - Hyperslab selection code was reworked to improve performance, getting more
+      than 10x speedup in some cases.
+
+    - The HDF5 Library was enhanced to open files with Unicode names on Windows.
+
+    - Deprecated H5Dvlen_reclaim() and replaced it with H5Treclaim().
+        This routine is meant to be used when resources are internally allocated
+        when reading data, i.e. when using either vlen or new reference types.
+        This is applicable to both attribute and dataset reads.
+
+    - h5repack was fixed to repack datasets with external storage
+      to other types of storage.
+
+
+Support for new platforms, languages and compilers.
+=======================================
+    - Added spectrum-mpi with clang, gcc and xl compilers on Linux 3.10.0
+    - Added OpenMPI 3.1 and 4.0 with clang, gcc and Intel compilers on Linux 3.10.0
+    - Added cray-mpich/PrgEnv with gcc and Intel compilers on Linux 4.14.180
+    - Added spectrum mpi with clang, gcc and xl compilers on Linux 4.14.0
+
+
+Bug Fixes since HDF5-1.12.0-alpha1 release
+==========================================
+    Library
+    -------
+    - Improved performance when creating a large number of small datasets by
+        retrieving default property values from the API context instead of doing
+        skip list searches.
+
+        (CJH - 2019/12/10, HDFFV-10658)
+
+    - Fixed user-created data access properties not existing in the property list
+        returned by H5Dget_access_plist. Thanks to Steven Varga for submitting a
+        reproducer and a patch.
+
+        (CJH - 2019/12/09, HDFFV-10934)
+
+    - Fixed an assertion failure in the parallel library when collectively
+        filling chunks. As it is required that chunks be written in
+        monotonically non-decreasing order of offset in the file, this assertion
+        was being triggered when the list of chunk file space allocations being
+        passed to the collective chunk filling routine was not sorted according
+        to this particular requirement.
+
+        The addition of a sort of the out of order chunks trades a bit of
+        performance for the elimination of this assertion and of any complaints
+        from MPI implementations about the file offsets used being out of order.
+
+        (JTH - 2019/10/07, HDFFV-10792)
+
+    FORTRAN library:
+    ----------------
+
+    - Corrected INTERFACE INTENT(IN) to INTENT(OUT) for buf_size in h5fget_file_image_f.
+
+        (MSB - 2020/2/18, HDFFV-11029)
+
+    Java Library:
+    ----------------
+    - Added ability to test java library with VOLs.
+
+        Created new CMake script that combines the java and vol test scripts.
+
+        (ADB - 2020/02/03, HDFFV-10996)
+
+    - Tests fail for non-English locale.
+
+        In the JUnit tests with a non-English locale, only the part before
+        the decimal comma is replaced by XXXX and this leads to a comparison
+        error. Changed the regex for the Time substitution.
+
+        (ADB - 2020/01/09, HDFFV-10995)
+
+    Tools:
+    ------
+    - h5repack was fixed to repack the reference attributes properly.
+        The code line that checks if the update of reference inside a compound
+        datatype is misplaced outside the code block loop that carries out the
+        check. In consequence, the next attribute that is not the reference
+        type was repacked again as the reference type and caused the failure of
+        repacking. The fix is to move the corresponding code line to the correct
+        code block.
+
+        (KY -2020/02/10, HDFFV-11014)
+
+    - h5diff was updated to use the new reference APIs.
+
+        h5diff uses the new reference APIs to compare references.
+        Attribute references can also be compared.
+
+        (ADB - 2019/12/19, HDFFV-10980)
+
+    - h5dump and h5ls were updated to use the new reference APIs.
+
+        The tools library now use the new reference APIs to inspect a
+        file. Also the DDL spec was updated to reflect the format
+        changes produced with the new APIs. The export API and support
+        functions in the JNI were updated to match.

+Known Problems
+==============
+    CMake files do not behave correctly with paths containing spaces.
+    Do not use spaces in paths because the required escaping for handling spaces
+    results in very complex and fragile build files.
+    ADB - 2019/05/07
+
+    At present, metadata cache images may not be generated by parallel
+    applications.  Parallel applications can read files with metadata cache
+    images, but since this is a collective operation, a deadlock is possible
+    if one or more processes do not participate.
+
+    Known problems in previous releases can be found in the HISTORY*.txt files
+    in the HDF5 source, and in the HDF5 Jira database, available at
+    https://jira.hdfgroup.org/.  Please register at https://www.hdfgroup.org to
+    create a free account for accessing the Jira database.  Please report any
+    new problems found to help@hdfgroup.org.
+
+
+CMake vs. Autotools installations
+=================================
+While both build systems produce similar results, there are differences.
+Each system produces the same set of folders on linux (only CMake works
+on standard Windows); bin, include, lib and share. Autotools places the
+COPYING and RELEASE.txt file in the root folder, CMake places them in
+the share folder.
+
+The bin folder contains the tools and the build scripts. Additionally, CMake
+creates dynamic versions of the tools with the suffix "-shared". Autotools
+installs one set of tools depending on the "--enable-shared" configuration
+option.
+  build scripts
+  -------------
+  Autotools: h5c++, h5cc, h5fc
+  CMake: h5c++, h5cc, h5hlc++, h5hlcc
+
+The include folder holds the header files and the fortran mod files. CMake
+places the fortran mod files into separate shared and static subfolders,
+while Autotools places one set of mod files into the include folder. Because
+CMake produces a tools library, the header files for tools will appear in
+the include folder.
+
+The lib folder contains the library files, and CMake adds the pkgconfig
+subfolder with the hdf5*.pc files used by the bin/build scripts created by
+the CMake build. CMake separates the C interface code from the fortran code by
+creating C-stub libraries for each Fortran library. In addition, only CMake
+installs the tools library. The names of the szip libraries are different
+between the build systems.
+
+The share folder will have the most differences because CMake builds include
+a number of CMake specific files for support of CMake's find_package and support
+for the HDF5 Examples CMake project.

+
+New Features
+============
+
+    Configuration
+    -------------
+    - CMake
+
+      Change minimum version to 3.10.
+
+      This change removes the need to support a copy of the FindMPI.cmake module,
+      which has been removed, along with its subfolder in the config/cmake_ext_mod
+      location.
+
+      (ADB - 2018/03/09)
+
+    - CMake
+
+      Add pkg-config file generation
+
+      Added pkg-config file generation for the C, C++, HL, and HL C++ libraries.
+      In addition, builds on linux will create h5cXXX scripts that use the pkg-config
+      files. This is a limited implementation of a script like autotools h5cc.
+
+      (ADB - 2018/03/08, HDFFV-4359)
+
+    - CMake
+
+      Refactor use of CMAKE_BUILD_TYPE for new variable, which understands
+      the type of generator in use.
+
+      Added new configuration macros to use new HDF_BUILD_TYPE variable. This
+      variable is set correctly for the type of generator being used for the build.
+
+      (ADB - 2018/01/08, HDFFV-10385, HDFFV-10296)
+
+    C++ API
+    -------
+    - The following C++ API wrappers have been added to class H5Location
+      + H5Lcreate_soft:
+        // Creates a soft link from link_name to target_name.
+        void link(const char *target_name, const char *link_name,...)
+        void link(const H5std_string& target_name,...)
+
+      + H5Lcreate_hard:
+        // Creates a hard link from new_name to curr_name.
+        void link(const char *curr_name, const Group& new_loc,...)
+        void link(const H5std_string& curr_name, const Group& new_loc,...)
+
+        // Creates a hard link from new_name to curr_name in the same location.
+        void link(const char *curr_name, const hid_t same_loc,...)
+        void link(const H5std_string& curr_name, const hid_t same_loc,...)
+
+        Note: previous version CommonFG::link will be deprecated.
+
+      + H5Lcopy:
+        // Copy an object from a group of file to another.
+        void copyLink(const char *src_name, const Group& dst,...)
+        void copyLink(const H5std_string& src_name, const Group& dst,...)
+
+        // Copy an object from a group of file to the same location.
+        void copyLink(const char *src_name, const char *dst_name,...)

+Support for New Platforms, Languages, and Compilers
+===================================================
+
+    - Added support for Visual Studio 2017 w/ Intel Fortran 18 on Windows 10 x64.
+
+
+Bug Fixes since HDF5-1.8.20
+===========================
+
+    - If an HDF5 file contains a filter pipeline message with a 'number of
+      filters' field that exceeds the maximum number of allowed filters,
+      the error handling code will attempt to dereference a NULL pointer.
+
+      This issue was reported to The HDF Group as issue #CVE-2017-17505.
+
+      NOTE: The HDF5 C library cannot produce such a file. This condition
+            should only occur in a corrupt (or deliberately altered) file
+            or a file created by third-party software.
+
+      This problem arose because the error handling code assumed that
+      the 'number of filters' field implied that a dynamic array of that
+      size had already been created and that the cleanup code should
+      iterate over that array and clean up each element's resources. If
+      an error occurred before the array has been allocated, this will
+      not be true.
+
+      This has been changed so that the number of filters is set to
+      zero on errors. Additionally, the filter array traversal in the
+      error handling code now requires that the filter array not be NULL.
+
+      (DER - 2018/02/06, HDFFV-10354)
+
+    - If an HDF5 file contains a filter pipeline message which contains
+      a 'number of filters' field that exceeds the actual number of
+      filters in the message, the HDF5 C library will read off the end of
+      the read buffer.
+
+      This issue was reported to The HDF Group as issue #CVE-2017-17506.
+
+      NOTE: The HDF5 C library cannot produce such a file. This condition
+            should only occur in a corrupt (or deliberately altered) file
+            or a file created by third-party software.
+
+      The problem was fixed by passing the buffer size with the buffer
+      and ensuring that the pointer cannot be incremented off the end
+      of the buffer. A mismatch between the number of filters declared
+      and the actual number of filters will now invoke normal HDF5
+      error handling.
+
+      (DER - 2018/02/26, HDFFV-10355)
+
+    - If an HDF5 file contains a malformed compound datatype with a
+      suitably large offset, the type conversion code can run off
+      the end of the type conversion buffer, causing a segmentation
+      fault.
+
+      This issue was reported to The HDF Group as issue #CVE-2017-17507.
+
+      NOTE: The HDF5 C library cannot produce such a file. This condition
+            should only occur in a corrupt (or deliberately altered) file
+            or a file created by third-party software.
+
+      THE HDF GROUP WILL NOT FIX THIS BUG AT THIS TIME
+
+      Fixing this problem would involve updating the publicly visible
+      H5T_conv_t function pointer typedef and versioning the API calls
+      which use it. We normally only modify the public API during
+      major releases, so this bug will not be fixed at this time.
+
+      (DER - 2018/02/26, HDFFV-10356)
+
+    - If an HDF5 file contains a malformed compound type which contains
+      a member of size zero, a division by zero error will occur while
+      processing the type.
+
+      This issue was reported to The HDF Group as issue #CVE-2017-17508.
+
+      NOTE: The HDF5 C library cannot produce such a file. This condition
+            should only occur in a corrupt (or deliberately altered) file
+            or a file created by third-party software.
+
+      Checking for zero before dividing fixes the problem. Instead of the
+      division by zero, the normal HDF5 error handling is invoked.
+
+      (DER - 2018/02/26, HDFFV-10357)
+
+    - If an HDF5 file contains a malformed symbol table node that declares
+      it contains more symbols than it actually contains, the library
+      can run off the end of the metadata cache buffer while processing
+      the symbol table node.
+
+      This issue was reported to The HDF Group as issue #CVE-2017-17509.
+
+      NOTE: The HDF5 C library cannot produce such a file. This condition
+            should only occur in a corrupt (or deliberately altered) file
+            or a file created by third-party software.
+
+      Performing bounds checks on the buffer while processing fixes the
+      problem. Instead of the segmentation fault, the normal HDF5 error
+      handling is invoked.
+
+      (DER - 2018/03/12, HDFFV-10358)
+
+
+    Configuration
+    -------------
+    - Library
+
+      Moved the location of gcc attribute.
+
+      The gcc attribute(no_sanitize), named as the macro HDF_NO_UBSAN,
+      was located after the function name. Builds with GCC 7 did not
+      indicate any problem, but GCC 8 issued errors. Moved the
+      attribute before the function name, as required.
+
+      (ADB 2018/05/22, HDFFV-10473)
+
+    - CMake
+
+      Update CMake commands configuration.
+
+      A number of improvements were made to the CMake commands. Most
+      changes simplify usage or eliminate unused constructs. Also,
+      some changes support better cross-platform support.
+
+      (ADB - 2018/02/01, HDFFV-10398)
+
+    - CMake
+
+      Correct usage of CMAKE_BUILD_TYPE variable.
+
+      The use of the CMAKE_BUILD_TYPE is incorrect for multi-config
+      generators (Visual Studio and XCode) and is optional for single
+      config generators. Created a new macro to check
+        GLOBAL PROPERTY -> GENERATOR_IS_MULTI_CONFIG
+      Created two new HDF variable, HDF_BUILD_TYPE and HDF_CFG_BUILD_TYPE.
+      Defaults for these variables is "Release".
+
+      (ADB - 2018/01/10, HDFFV-10385)
+
+    - CMake
+
+      Add replacement of fortran flags if using static CRT.
+
+      Added TARGET_STATIC_CRT_FLAGS call to HDFUseFortran.cmake file in
+      config/cmake_ext_mod folder.
+
+      (ADB - 2018/01/08, HDFFV-10334)
+
+
+    Library
+    -------
+    - Utility function can not handle lowercase Windows drive letters
+
+      Added call to toupper function for drive letter.
+
+      (ADB - 2017/12/18, HDFFV-10307)
+
+
+    Tools
+    -----
+    - h5repack
+
+      h5repack changes the chunk parameters when a change of layout is not
+      specified and a filter is applied.
+
+      HDFFV-10297, HDFFV-10319 reworked code for h5repack and h5diff code
+      in the tools library. The check for an existing layout was incorrectly
+      placed into an if block and not executed. The check was moved into
+      the normal path of the function.
+
+      (ADB - 2018/02/21, HDFFV-10412)
+
+    - h5dump
+
+      the tools library will hide the error stack during file open.
+
+      While this is preferable almost always, there are reasons to enable
+      display of the error stack when a tool will not open a file. Adding an
+      optional argument to the --enable-error-stack will provide this use case.
+      As an optional argument it will not affect the operation of the
+      --enable-error-stack. h5dump is the only tool to implement this change.
+
+      (ADB - 2018/02/15, HDFFV-10384)
+
+    - h5dump
+
+      h5dump would output an indented blank line in the filters section.
+
+      h5dump overused the h5tools_simple_prefix function, which is a
+      function intended to account for the data index (x,y,z) option.
+      Removed the function call for header information.
+
+      (ADB - 2018/01/25, HDFFV-10396)
+
+    - h5repack
+
+      h5repack incorrectly searched internal object table for name.
+
+      h5repack would search the table of objects for a name, if the
+      name did not match it tried to determine if the name without a
+      leading slash would match. The logic was flawed! The table
+      stored names(paths) without a leading slash and did a strstr
+      of the table path to the name.
+      The assumption was that if there was a difference of one then
+      it was a match, however "pressure" would match "/pressure" as
+      well as "/pressure1", "/pressure2", etc. Changed logic to remove
+      any leading slash and then do a full compare of the name.
+
+      (ADB - 2018/01/18, HDFFV-10393)
+
+    - h5repack
+
+      h5repack failed to handle command line parameters for customer filters.
+
+      User defined filter parameter conversions would fail when integers
+      were represented on the command line with character strings
+      larger than 9 characters. Increased local variable array for storing
+      the current command line parameter to prevent buffer overflows.
+
+      (ADB - 2018/01/17, HDFFV-10392)
+
+    - h5diff
+
+      h5diff seg faulted if comparing VL strings against fixed strings.
+
+      Reworked solution for HDFFV-8625 and HDFFV-8639. Implemented the check
+      for string objects of same type in the diff_can_type function by
+      adding an if(tclass1 == H5T_STRING) block. This "if block" moves the
+      same check that was added for attributes to this function, which is
+      used by all object types. This function handles complex type structures.
+      Also added a new test file in h5diffgentest for testing this issue
+      and removed the temporary files used in the test scripts.
+
+      (ADB - 2018/01/04, HDFFV-8745)
+
+
+    C++ API
+    -------
+    - Removal of memory leaks
+
+      A private function was inadvertently called, causing memory leaks.  This
+      is now fixed.
+
+      (BMR - 2018/04/12 - User reported in email)
+
+    - Changes in exception classes
+
+      Some exception classes are reorganized to reflect the HDF5 object
+      hierarchy and allow customization.
+        DataSetIException -> LocationException -> Exception
+        DataTypeIException -> LocationException -> Exception
+        GroupIException -> LocationException -> Exception
+        AttributeIException -> LocationException -> Exception
+        FileIException -> GroupIException -> LocationException -> Exception
+      Member functions in H5Location and H5Object now throw specific exceptions
+      associated with the invoking objects.
+
+      (BMR - 2018/05/11)
+
+    - H5Location::closeObjId is made static
+      (BMR - 2018/05/11)
+
+    - H5A wrappers in H5Location are removed as they have been in H5Object.
+      (BMR - 2018/05/11)

+Known Problems
+==============
+
+    The dynamically loaded plugin test libraries require undefined references
+    to HDF5 functions to be resolved at runtime in order to function properly.
+    With autotools on CYGWIN this results in build errors, and we have not
+    found a solution that satisfies both.  Therefore the dynamically loaded
+    plugin tests have been disabled on CYGWIN.
+
+    Mac OS X 10.13 added additional subdirectory structure in .libs for shared
+    libraries.  Consequently "make check" will fail testing java and dynamically
+    loaded plugin test libraries attempting to copy files from the previous
+    locations in .libs directories.  This will be addressed in the next release
+    when support for the Mac OS X 10.13 platform is added.
+
+    Known problems in previous releases can be found in the HISTORY*.txt files
+    in the HDF5 source. Please report any new problems found to
+    help@hdfgroup.org.

+New Features
+============
+
+    Tools
+    -----
+    - h5diff
+
+      h5diff has new option enable-error-stack.
+
+      Updated h5diff with the --enable-error-stack argument, which
+      enables the display of the hdf5 error stack. This completes the
+      improvement to the main tools; h5copy, h5diff, h5dump, h5ls and
+      h5repack.
+
+      (ADB - 2017/08/30, HDFFV-9774)
+
+
+    C++ API
+    -------
+    - The following C++ API wrappers have been added to the C++ Library:
+
+        // Creates a binary object description of this datatype.
+        void DataType::encode() - C API H5Tencode()
+
+        // Returns the decoded type from the binary object description.
+        DataType::decode() - C API H5Tdecode()
+        ArrayType::decode() - C API H5Tdecode()
+        CompType::decode() - C API H5Tdecode()
+        DataType::decode() - C API H5Tdecode()
+        EnumType::decode() - C API H5Tdecode()
+        FloatType::decode() - C API H5Tdecode()
+        IntType::decode() - C API H5Tdecode()
+        StrType::decode() - C API H5Tdecode()
+        VarLenType::decode() - C API H5Tdecode()
+
+        // Three overloaded functions to retrieve information about an object
+        H5Location::getObjectInfo() - H5Oget_info()/H5Oget_info_by_name()
+
+      (BMR - 2017/10/17, HDFFV-10175)
+
+    - New constructors to open existing datatypes added in ArrayType,
+      CompType, DataType, EnumType, FloatType, IntType, StrType, and
+      VarLenType.
+
+      (BMR - 2017/10/17, HDFFV-10175)
+
+    - A document is added to the HDF5 C++ API Reference Manual to show the
+      mapping from a C API to C++ wrappers.  It can be found from the main
+      page of the C++ API Reference Manual.
+
+      (BMR - 2017/10/17, HDFFV-10151)
+
+
+    High-Level APIs
+    ---------------
+    - H5DOread_chunk
+
+      Users wanted to read compressed data directly from a file without any
+      processing by the HDF5 data transfer pipeline, just as they were able
+      to write it directly to a file with H5DOwrite_chunk.
+
+      New API function, corresponding to existing function H5DOwrite_chunk.
+      H5DOread_chunk reads a raw data chunk directly from a chunked dataset
+      in the file into the application buffer, bypassing the library’s internal
+      data transfer pipeline, including filters.
+
+      (VC - 2017/05/02, HDFFV-9934)
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+
+    - Added NAG compiler
+
+
+Bug Fixes since HDF5-1.8.19
+===========================
+
+    Configuration
+    -------------
+    - cmake
+
+      The hdf5 library used shared szip and zlib, which needlessly required
+      applications to link with the same szip and zlib libraries.
+
+      Changed the target_link_libraries commands to use the static libs.
+      Removed improper link duplication of szip and zlib.
+      Adjusted the link dependencies and the link interface values of
+      the target_link_libraries commands.
+
+      (ADB - 2017/11/14, HDFFV-10329)
+
+    - cmake MPI
+
+      CMake implementation for MPI was problematic and would create incorrect
+      MPI library references in the hdf5 libraries.
+
+      Reworked the CMake MPI code to properly create CMake targets.Also merged
+      the latest CMake FindMPI.cmake changes to the local copy. This is necessary
+      until HDF changes the CMake minimum to 3.9 or greater.
+
+      (ADB - 2017/11/02, HDFFV-10321)
+
+
+    - Fixed Fortran linker flags when using the NAG Fortran compiler (autotools).
+
+      (HDFFV-10037, MSB, 2017/10/21)
+
+    - cmake
+
+      Too many commands for POST_BUILD step caused command line to be
+      too big on windows.
+
+      Changed foreach of copy command to use a custom command with the
+      use of the HDFTEST_COPY_FILE macro.
+
+      (ADB - 2017/07/12, HDFFV-10254)
+
+
+    Library
+    -------
+    - filter plugin handling in H5PL.c and H5Z.c
+
+      It was discovered that the dynamic loading process used by
+      filter plugins had issues with library dependencies.
+
+      CMake build process changed to use LINK INTERFACE keywords, which
+      allowed HDF5 C library to make dependent libraries private. The
+      filter plugin libraries no longer require dependent libraries
+      (such as szip or zlib) to be available.
+             (ADB - 2017/11/16, HDFFV-10328)
+
+    - Fix rare object header corruption bug
+
+      In certain cases, such as when converting large attributes to dense
+      storage, an error could occur which would either fail an assertion or
+      cause file corruption. Fixed and added test.
+
+      (NAF - 2017/11/14, HDFFV-10274)
+
+    - H5Zfilter_avail in H5Z.c
+
+      The public function checked for plugins, while the private
+      function did not.
+
+      Modified H5Zfilter_avail and private function, H5Z_filter_avail.
+      Moved check for plugin from public to private function. Updated
+      H5P__set_filter due to change in H5Z_filter_avail. Updated tests.
+
+      (ADB - 2017/10/10, HDFFV-10297, HDFFV-10319)
+
+    - Fix H5Sencode bug when num points selected is >2^32
+
+      Modified to fail if the 32 bit limit is exceeded when encoding either
+      offsets or counts in the selection.
+
+      (HDFFV-10323, VC, 2017/09/07)
+
+    - Fix H5HL_offset_into()
+
+      (1) Fix H5HL_offset_into() to return error when offset exceeds heap data
+          block size.
+      (2) Fix other places in the library that call this routine to detect
+          error routine.
+
+      (HDFFV-10216, VC, 2017/09/05)
+
+
+    Tools
+    -----
+    - h5repack
+
+      h5repack failed to copy a dataset with existing filter.
+
+      Reworked code for h5repack and h5diff code in tools library. Added
+      improved error handling, cleanup of resources and checks of calls.
+      Modified H5Zfilter_avail and private function, H5Z_filter_avail.
+      Moved check for plugin from public to private function. Updated
+      H5P__set_filter due to change in H5Z_filter_avail. Updated tests.
+      Note, h5repack output display has changed to clarify the individual
+      steps of the repack process. The output indicates if an operation
+      applies to all objects. Lines with notation and no information
+      have been removed.
+
+      (ADB - 2017/10/10, HDFFV-10297, HDFFV-10319)
+
+    - h5repack
+
+      h5repack always set the User Defined filter flag to H5Z_FLAG_MANDATORY.
+
+      Added another parameter to the 'UD=' option to set the flag by default
+      to '0' or H5Z_FLAG_MANDATORY, the other choice is '1' or H5Z_FLAG_OPTIONAL.
+
+      (ADB - 2017/08/31, HDFFV-10269)
+
+    - h5ls
+
+      h5ls generated error on stack when it encountered a H5S_NULL
+      dataspace.
+
+      Adding checks for H5S_NULL before calling H5Sis_simple (located
+      in the h5tools_dump_mem function) fixed the issue.
+
+      (ADB - 2017/08/17, HDFFV-10188)
+
+    - h5dump
+
+      h5dump segfaulted on output of XML file.
+
+      Function that escape'd strings used the full buffer length
+      instead of just the length of the replacement string in a
+      strncpy call. Using the correct length fixed the issue.
+
+      (ADB - 2017/08/01, HDFFV-10256)
+
+    - h5diff
+
+      h5diff segfaulted on compare of a  NULL variable length string.
+
+      Improved h5diff compare of strings by adding a check for
+      NULL strings and setting the lengths to zero.
+
+      (ADB - 2017/07/25, HDFFV-10246)
+
+    - h5import
+
+      h5import crashed trying to import data from a subset of a dataset.
+
+      Improved h5import by adding the SUBSET keyword. h5import understands
+      to use the Count times the Block as the size of the dimensions.
+      Added INPUT_B_ORDER keyword to old-style configuration files.
+      The import from h5dump function expects the binary files to use native
+      types (FILE '-b' option) in the binary file.
+
+      (ADB - 2017/06/15, HDFFV-10219)
+
+
+    C++ API
+    -------
+    - Marked the following functions deprecated because they were moved to
+      class H5Object:
+        H5Location::createAttribute()
+        H5Location::openAttribute()
+        H5Location::attrExists()
+        H5Location::removeAttr()
+        H5Location::renameAttr()
+        H5Location::getNumAttrs()
+

+Known Problems
+==============
+
+    The dynamically loaded plugin test libraries require undefined references
+    to HDF5 functions to be resolved at runtime in order to function properly.
+    With autotools on CYGWIN this results in build errors, and we have not
+    found a solution that satisfies both.  Therefore the dynamically loaded
+    plugin tests have been disabled on CYGWIN.
+
+    Mac OS X 10.13 added additional subdirectory structure in .libs for shared
+    libraries.  Consequently "make check" will fail testing java and dynamically
+    loaded plugin test libraries attempting to copy files from the previous
+    locations in .libs directories.  This will be addressed in the next release
+    when support for the Mac OS X 10.13 platform is added.
+
+    Known problems in previous releases can be found in the HISTORY*.txt files
+    in the HDF5 source. Please report any new problems found to
+    help@hdfgroup.org.

+New Features
+============
+
+    Configuration
+    --------------
+    - CMake in the Tools
+
+      User-defined filters on Windows require that tools be built
+      with shared libraries.
+
+      CMake command code added to build tools with
+      shared libraries as well as with static libraries.
+
+      (ADB - 2017/02/07, HDFFV-10123)
+
+
+    Library
+    -------
+    - H5PL package
+
+      Users would like to be able to set the plugin path programmatically
+      instead of through the environment variable.
+
+      H5PL package obtained new APIs for manipulating the entries of
+      the plugin path table. The new APIs are;
+        H5PLappend  - Insert a plugin path at the end of the list.
+        H5PLprepend - Insert a plugin path at the beginning of the list.
+        H5PLreplace - Replace the path at the specified index.
+        H5PLinsert  - Insert a plugin path at the specified index, moving
+                      other paths after the index.
+        H5PLremove  - Remove the plugin path at the specifed index and
+                      compacting the list.
+        H5PLget     - Query the plugin path at the specified index.
+        H5PLsize    - Query the size of the current list of plugin paths.
+
+      (ADB - 2017/04/04, HDFFV-10143)
+
+    - H5Dget_chunk_storage_size
+
+      The storage size of a chunk in the file is needed to determine the size
+      of the buffer to be allocated for reading a chunk directly from a file.
+
+      New API function gets the size in bytes currently allocated within a
+      file for a raw data chunk in a dataset.  This function was added to get
+      the chunk size in support of the implementation of H5DOread_chunks, but
+      may also be useful for other purposes.
+
+      (VC - 2017/05/02, HDFFV-9934)
+
+    C++ API
+    -------
+    - The following C++ API wrappers have been added to the C++ Library:
+        // Determines if a name exists.
+        H5Location::nameExists() - C API H5Lexists()
+
+        // Checks if an ID is valid.
+        IdComponent::isValid() - C API H5Iis_valid()
+
+        // Sets the number of soft or user-defined links that can be
+        // traversed before a failure occurs.
+        LinkAccPropList::setNumLinks() - C API H5Pset_nlinks()
+
+        // Gets the number of soft or user-defined link traversals allowed
+        LinkAccPropList::getNumLinks() - C API H5Pget_nlinks()
+
+        // Returns a copy of the creation property list of a datatype.
+        DataType::getCreatePlist() - C API H5Tget_create_plist()
+
+        // Opens an object within a location, regarless its type.
+        H5Location::openObjId() - C API H5Oopen()
+        H5Location::openObjId() - C API H5Oopen()
+
+        // Closes an object opened by openObjId().
+        H5Location::closeObjId() - C API H5Oclose()
+
+        // Gets general information about a file.
+        H5File::getFileInfo() - C API H5Fget_info()
+
+        // Returns the header version of an HDF5 object.
+        H5Object::objVersion() - C API H5Oget_info()
+
+      (BMR, 2017/05/13, HDFFV-10004, HDFFV-10156)
+
+    - New class LinkAccPropList is added for link access proprety list
+
+      (BMR, 2017/05/13, HDFFV-10156)
+
+    High-Level APIs
+    ---------------
+    - H5DOread_chunk
+
+      Users wanted to read compressed data directly from a file without any
+      processing by the HDF5 data transfer pipeline, just as they were able
+      to write it directly to a file with H5DOwrite_chunk.
+
+      New API function, corresponding to existing function H5DOwrite_chunk.
+      H5DOread_chunk reads a raw data chunk directly from a chunked dataset
+      in the file into the application buffer, bypassing the library’s internal
+      data transfer pipeline, including filters.

+Support for New Platforms, Languages, and Compilers
+===================================================
+
+    - Added OpenMPI 2.0.1 compiled with GCC 4.9.3
+
+
+Bug Fixes since HDF5-1.8.18
+===========================
+
+    Configuration
+    -------------
+    - Support for Fortran shared libraries on OS X with autotools now
+      works. Cmake builds still disables Fortran shared libraries on OS X.
+      (MSB - 2017/04/30, HDFFV-2772)
+
+
+    Library
+    -------
+    - bitfield datatypes
+
+      bitfield datatypes did not fully support endianness of the data.
+
+      Improved the endianness of bitfield datatypes by adding missing functional
+      code. This code used integer types as a template.
+
+      (ADB - 2017/05/12, HDFFV-10186)
+
+    - Newly created datasets with H5D_COMPACT layout failed to open after
+      several H5Dopen/H5Dclose cycles.
+
+      The layout "dirty" flag for a compact dataset is now properly reset
+      before flushing the message.
+
+      (VC - 2017/05/11, HDFFV-10051)
+    - Missing #ifdef __cplusplus macros were added to the generated H5Epubgen.h file.
+
+      (DER - 2017/04/25, HDFFV-9638)
+
+
+    Tools
+    -----
+    - h5repack
+
+      h5repack did not maintain the creation order flag of the root
+      group.
+
+      Improved h5repack by reading the creation order and applying the
+      flag to the new root group. Also added arguments to set the
+      order and index direction, which applies to the traversing of the
+      original file, on the command line.
+
+      (ADB - 2017/05/26, HDFFV-8611)
+
+    - h5diff
+
+      h5diff failed to account for strpad type and null terminators
+      of char strings. Also, h5diff failed to account for string length
+      differences and would give a different result depending on file
+      order in the command line.
+
+      Improved h5diff compare of strings and arrays by adding a check for
+      string lengths and if the strpad was null filled.
+
+      (ADB - 2017/05/18, HDFFV-9055, HDFFV-10128)
+
+    - h5diff
+
+      h5diff help text about epsilon comparison was confusing.
+
+      Changed h5diff help text to indicate that the 'a' refers to the
+      datapoint in file1 and 'b' refers to the datapoint value in file2.
+
+      (ADB - 2017/05/16, HDFFV-9995)
+
+    - h5diff
+
+      h5diff did not report user-defined filter data differences correctly.
+
+      Improved h5diff compare of user-defined filter data by reporting an
+      error if the user-defined filter plugin cannot be found.
+
+      (ADB - 2017/01/18, HDFFV-9994)
+    C++ API
+    -------
+    - The class hierarchy is revised to better reflect the HDF5 model.
+      Class H5File is now derived from class Group instead of H5Location.
+      Class Attribute is now derived from H5Location instead of IdComponent.
+      Wrappers of H5A APIs in H5Location are now duplicated in H5Object,
+      the original wrappers in H5Location will be deprecated in future
+      releases.
+
+      (BMR - 2017/05/15, HDFFV-10156)

+
+Known Problems
+==============
+
+    The dynamically loaded plugin test libraries require undefined references
+    to HDF5 functions to be resolved at runtime in order to function properly.
+    With autotools on CYGWIN this results in build errors, and we have not
+    found a solution that satisfies both.  Therefore the dynamically loaded
+    plugin tests have been disabled on CYGWIN.
+
+    Known problems in previous releases can be found in the HISTORY*.txt files

+
+    Configuration
+    -------------
+
+    - CMake: Added NAMESPACE hdf5:: to package configuration files to allow
+      projects using installed HDF5 binaries built with CMake to link with
+      them without specifying the HDF5 library location via IMPORTED_LOCATION.
+
+      (ADB, 2016/10/17, HDFFV-10003)
+
+
+    - CMake: Changed the CTEST_BUILD_CONFIGURATION option to
+      CTEST_CONFIGURATION_TYPE as recommended by the CMake documentation.
+
+      (ADB, 2016/10/17, HDFFV-9971)

+===================================================
+
+
+
+Bug Fixes since HDF5-1.8.17
+===========================
+
+    Configuration
+    -------------
+
+    - Fixed a problem preventing HDF5 to be built on 32-bit CYGWIN by
+      condensing cygwin configuration files into a single file and
+      removing outdated compiler settings.
+
+      (ABD, 2016/07/12, HDFFV-9946)
+
+
+    - CMake: Fixed a command length overflow error by converting custom
+      commands inside CMakeTest.cmake files into regular dependencies and
+      targets.
+
+      (ABD, 2016/07/12, HDFFV-9939)
+
+
+    - CMake: Fixed a timeout error that would occasionally occur when running
+      the virtual file driver tests simultaneously due to test directory and file
+      name collisions.
+
+      (ABD, 2016/09/19, HDFFV-9431)
+
+
+    Library
+    -------
+
+    - Fixed a memory leak that would occur when the library allocated memory
+      for an external file prefix (H5Pset_efile_prefix) and failed to free it.
+
+      (DER, 2016/04/29)
+
+
+    - Fixed an error that would occur when calling H5Adelete on an attribute
+      which is attached to an externally linked object in the target file and
+      whose datatype is a committed datatype in the main file.
+
+      (VC, 2016-07-04, HDFFV-9940)
+
+
+    - Fixed a problem where a plugin compiled into a DLL in the default plugin
+      directory could not be found by the HDF5 library at runtime on Windows
+      when the HDF5_PLUGIN_PATH environment variable was not set.
+
+      (ABD, 2016/08/01, HDFFV-9706)
+
+
+    - Fixed an issue where H5Pset_alignment could result in misaligned blocks
+      with some input combinations, causing an assertion failure in debug mode.
+
+      (NAF, 2016/08/11, HDFFV-9948)
+
+
+    - A number of issues were fixed when reading/writing from/to corrupted
+      files to ensure that the library fails gracefully in these cases:
+
+      * Writing to a corrupted file that has an object message which is
+        incorrectly marked as sharable on disk results in a buffer overflow /
+        invalid write instead of a clean error message.
+
+      * Decoding data from a corrupted file with a dataset encoded with the
+        H5Z_NBIT decoding can result in a code execution vulnerability under
+        the context of the application using the HDF5 library.
+
+      * When decoding an array datatype from a corrupted file, the HDF5 library
+        fails to return an error in production if the number of dimensions
+        decoded is greater than the maximum rank.
+
+      * When decoding an "old style" array datatype from a corrupted file, the
+        HDF5 library fails to return an error in production if the number of
+        dimensions decoded is greater than the maximum rank.
+
+      (NAF, 2016/10/06, HDFFV-9950, HDFFV-9951, HDFFV-9992, HDFFV-9993)
+
+
+    - Fixed an error that would occur when copying an object with an attribute
+      which is a compound datatype consisting of a variable length string.
+
+      (VC, 2016-10-17, HDFFV-7991)
+
+
+    Parallel Library
+    ----------------
+
+    - Fixed a bug that could occur when allocating a chunked dataset in parallel
+      with an alignment set and an alignment threshold greater than the chunk
+      size but less than or equal to the raw data aggregator size.
+
+      (NAF, 2016/08/11, HDFFV-9969)
+
+
+    Performance
+    -------------
+    - None
+
+
+    Tools
+    -----
+
+    - Fixed an error in the compiler wrapper scripts (h5cc, h5fc, et al.)
+      in which they would erroneously drop the file argument specified via
+      the -o flag when the -o flag was specified before the -c flag on the
+      command line, resulting in a failure to compile.
+
+      (LRK, 2016/06/08, HDFFV-9938, HDFFV-9530)
+
+
+    - h5repack User Defined (UD) filter parameters were not parsed correctly.
+
+      The UD filter parameters were not being parsed correctly. Reworked coding
+      section to parse the correct values and verify number of parameters.
+
+      (ADB, 2016/10/19, HDFFV-9996, HDFFV-9974, HDFFV-9515, HDFFV-9039)
+
+
+    Fortran API
+    -----------
+
+    - Fortran library fails to compile and fails tests with NAG compiler.
+
+      * Removed the non-standard assumption that KIND=SIZEOF, in the HDF5
+        configure programs.
+      * Removed Fortran 66 character/integer conversions from tests.
+      * Removed the use of C_SIZEOF in the test programs
+      * Changed to using STORAGE_SIZE in the test programs if available. Otherwise,
+        uses C_SIZEOF or SIZEOF.
+
+      (MSB, 2016/9/22, HDFFV-9973)
+
+
+    - Fortran segfaults for F03 tests with NAG compiler
+
+      * Removed INTENT(OUT) from 'fillvalue' in F2003 interface
+        for H5Pget_fill_value_f.
+
+      (MSB, 2016/9/22, HDFFV-9980)
+
+
+    C++ API
+    -------
+
+    - The macro H5_NO_NAMESPACE is deprecated from the HDF5 C++ API library.
+      In future releases, the macros H5_NO_STD and OLD_HEADER_FILENAME may
+      also be removed.
+
+      (BMR, 2016/10/27, HDFFV-9532)
+
+
+    High-Level APIs:
+    ---------------
+
+    - The high-level API Packet Table (PT) did not write data correctly when
+      the datatype is a compound type that has string type as one of the
+      members.  This problem started in 1.8.15, after the fix of HDFFV-9042
+      was applied, which caused the Packet Table to use native type to access
+      the data.  It should be up to the application to specify whether the
+      buffer to be read into memory in the machine’s native architecture.
+      Thus, the PT is fixed to not use native type but to make a copy of the
+      user's provided datatype during creation or the packet table's datatype
+      during opening.  If an application wishes to use native type to read the
+      data, then the application will request that.  However, the Packet Table
+      doesn't provide a way to specify memory datatype in this release.  This
+      feature will be available in future releases, HDFFV-10023.

+
+Known Problems
+==============
+* On windows platforms in debug configurations, the VFD flush1 tests will fail
+  with the split and multi VFD drivers. These tests will display a modal debug
+  dialog which must be answered or wait for the test timeout to expire.
+  (ADB - 2014/06/23 - HDFFV-8851)
+
+* CLANG compiler with the options -fcatch-undefined-behavior and -ftrapv
+  catches some undefined behavior in the alignment algorithm of the macro DETECT_I
+  in H5detect.c (Issue 8147).  Since the algorithm is trying to detect the alignment
+  of integers, ideally the flag -fcatch-undefined-behavior shouldn't to be used for
+  H5detect.c. In the future, we can separate flags for H5detect.c from the rest of
+  the library. (SLU - 2013/10/16)
+
+* Make provided by Solaris fails in "make check". Solaris users should use
+  gmake to build and install the HDF5 software. (AKC - 2013/10/08 - HDFFV-8534)
+
+* The C++ and FORTRAN bindings are not currently working on FreeBSD with the
+  native release 8.2 compilers (4.2.1), but are working with gcc 4.6 from the
+  ports (and probably gcc releases after that).
+  (QAK - 2012/10/19)
+
+* The following h5dump test case fails in BG/P machines (and potentially other
+  machines that use a command script to launch executables):
+
+   h5dump --no-compact-subset -d "AHFINDERDIRECT::ah_centroid_t[0] it=0 tl=0"
+     tno-subset.h5
+
+  This is due to the embedded spaces in the dataset name being interpreted
+  by the command script launcher as meta-characters, thus passing three
+  arguments to h5dump's -d flag. The command passes if run by hand, just
+  not via the test script.
+  (AKC - 2012/05/03)
+
+* The STDIO VFD does not work on some architectures, possibly due to 32/64
+  bit or large file issues.  The basic STDIO VFD test is known to fail on
+  64-bit SunOS 5.10 on SPARC when built with -m64 and 32-bit OS X/Darwin
+  10.7.0.  The STDIO VFD test has been disabled while we investigate and
+  a fix should appear in a future release.
+  (DER - 2011/10/14 - HDFFV-8235)
+
+* h5diff can report inconsistent results when comparing datasets of enum type
+  that contain invalid values.  This is due to how enum types are handled in
+  the library and will be addressed in a future release.
+  (DER - 2011/10/14 - HDFFV-7527)
+
+* The links test can fail under the stdio VFD due to some issues with external
+  links.  This will be investigated and fixed in a future release.
+  (DER - 2011/10/14 - HDFFV-7768)
+
+* After the shared library support was fixed for some bugs, it was discovered
+  that "make prefix=XXX install" no longer works for shared libraries. It
+  still works correctly for static libraries. Therefore, if you want to
+  install the HDF5 shared libraries in a location such as /usr/local/hdf5,
+  you need to specify the location via the --prefix option during configure
+  time. E.g, ./configure --prefix=/usr/local/hdf5 ...
+  (AKC - 2011/05/07 - HDFFV-7583)
+
+* The parallel test, t_shapesame, in testpar/, may run for a long time and may
+  be terminated by the alarm signal.  If that happens, one can increase the
+  alarm seconds (default is 1200 seconds = 20 minutes) by setting the
+  environment variable, $HDF5_ALARM_SECONDS, to a larger value such as 3600
+  (60 minutes).  Note that the t_shapesame test may fail in some systems
+  (see the "While working on the 1.8.6 release..." problem below).  If
+  it does, it will waste more time if $HDF5_ALARM_SECONDS is set
+  to a larger value.
+  (AKC - 2011/05/07)
+
+* Shared Fortran libraries are not quite working on AIX. While they are
+  generated when --enable-shared is specified, the fortran and hl/fortran
+  tests fail. the issue. HL and C++ shared libraries should now be
+  working as intended, however.
+  (MAM - 2011/04/20)
+
+* While working on the 1.8.6 release of HDF5, a bug was discovered that can
+  occur when reading from a dataset in parallel shortly after it has been
+  written to collectively. The issue was exposed by a new test in the parallel
+  HDF5 test suite, but had existed before that. We believe the problem lies with
+  certain MPI implementations and/or file systems.
+
+  We have provided a pure MPI test program, as well as a standalone HDF5
+  program, that can be used to determine if this is an issue on your system.
+  They should be run across multiple nodes with a varying number of processes.
+  These programs can be found at:
+  http://www.hdfgroup.org/ftp/HDF5/examples/known_problems/
+  (NAF - 2011/01/19)
+
+* All the VFL drivers aren't backward compatible.  In H5FDpublic.h, the
+  structure H5FD_class_t changed in 1.8.  There is new parameter added to
+  get_eoa and set_eoa callback functions.  A new callback function
+  get_type_map was added in.  The public function H5FDrealloc was taken
+  out in 1.8.  The problem only happens when users define their own driver
+  for 1.6 and try to plug in 1.8 library.  Because there's only one user
+  complaining about it, we (Elena, Quincey, and I) decided to leave it as
+  it is (see bug report #1279).  Quincey will make a plan for 1.10.
+  (SLU - 2010/02/02)
+
+* The --enable-static-exec configure flag will only statically link libraries
+  if the static version of that library is present. If only the shared version
+  of a library exists (i.e., most system libraries on Solaris, AIX, and Mac,
+  for example, only have shared versions), the flag should still result in a
+  successful compilation, but note that the installed executables will not be
+  fully static. Thus, the only guarantee on these systems is that the
+  executable is statically linked with just the HDF5 library.
+  (MAM - 2009/11/04)
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+  with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+  There was a bug in the calculation of the Fletcher32 checksum in the
+  library before v1.6.3; the checksum value was not consistent between big-
+  endian and little-endian systems.  This bug was fixed in Release 1.6.3.
+  However, after fixing the bug, the checksum value was no longer the same as
+  before on little-endian system.  Library releases after 1.6.4 can still read
+  datasets created or rewritten with an HDF5 library of v1.6.2 or before.
+  (SLU - 2005/06/30)

+
+    - Add file locking configure and CMake options
+
+        HDF5 1.10.0 introduced a file locking scheme, primarily to help
+        enforce SWMR setup. Formerly, the only user-level control of the scheme
+        was via the HDF5_USE_FILE_LOCKING environment variable.
+
+        This change introduces configure-time options that control whether
+        or not file locking will be used and whether or not the library
+        ignores errors when locking has been disabled on the file system
+        (useful on some HPC Lustre installations).
+
+        In both the Autotools and CMake, the settings have the effect of changing
+        the default property list settings (see the H5Pset/get_file_locking()
+        entry, below).
+
+        The yes/no/best-effort file locking configure setting has also been
+        added to the libhdf5.settings file.
+
+        Autotools:
+
+            An --enable-file-locking=(yes|no|best-effort) option has been added.
+
+            yes:          Use file locking.
+            no:           Do not use file locking.
+            best-effort:  Use file locking and ignore "disabled" errors.
+
+        CMake:
+
+            Two self-explanatory options have been added:
+
+            HDF5_USE_FILE_LOCKING
+            HDF5_IGNORE_DISABLED_FILE_LOCKS
+
+            Setting both of these to ON is the equivalent to the Autotools'
+            best-effort setting.
+
+        NOTE:
+        The precedence order of the various file locking control mechanisms is:
+
+            1) HDF5_USE_FILE_LOCKING environment variable (highest)
+
+            2) H5Pset_file_locking()
+
+            3) configure/CMake options (which set the property list defaults)
+
+            4) library defaults (currently best-effort)

     - CMake option to link the generated Fortran MOD files into the include
       directory.
 
-      The Fortran generation of MOD files by a Fortran compile can produce
-      different binary files between SHARED and STATIC compiles with different
-      compilers and/or different platforms. Note that it has been found that
-      different versions of Fortran compilers will produce incompatible MOD
-      files. Currently, CMake will locate these MOD files in subfolders of
-      the include directory and add that path to the Fortran library target
-      in the CMake config file, which can be used by the CMake find library
-      process. For other build systems using the binary from a CMake install,
-      a new CMake configuration can be used to copy the pre-chosen version
-      of the Fortran MOD files into the install include directory.

-    - Add mingw CMake support with a toolchain file
-
-      There has been a number of mingw issues that has been linked under
-      HDFFV-10845. It has been decided to implement the CMake cross-compiling
-      technique of toolchain files. We will use a linux platform with the mingw
-      compiler stack for testing. Only the C language is fully supported, and
-      the error tests are skipped. The C++ language works for static but shared
-      builds has a shared library issue with the mingw Standard Exception Handling
-      library, which is not available on Windows. Fortran has a common cross-compile

-    - Add file locking configure and CMake options
-
-      HDF5 1.10.0 introduced a file locking scheme, primarily to help
-      enforce SWMR setup. Formerly, the only user-level control of the scheme
-      was via the HDF5_USE_FILE_LOCKING environment variable.
-
-      This change introduces configure-time options that control whether
-      or not file locking will be used and whether or not the library
-      ignores errors when locking has been disabled on the file system
-      (useful on some HPC Lustre installations).
-
-      In both the Autotools and CMake, the settings have the effect of changing
-      the default property list settings (see the H5Pset/get_file_locking()
-      entry, below).
-
-      The yes/no/best-effort file locking configure setting has also been
-      added to the libhdf5.settings file.
-
-      Autotools:
-
-        An --enable-file-locking=(yes|no|best-effort) option has been added.
-
-        yes:          Use file locking.
-        no:           Do not use file locking.
-        best-effort:  Use file locking and ignore "disabled" errors.
-
-      CMake:
-
-        Two self-explanatory options have been added:
-
-        HDF5_USE_FILE_LOCKING
-        HDF5_IGNORE_DISABLED_FILE_LOCKS
-
-        Setting both of these to ON is the equivalent to the Autotools'
-        best-effort setting.
-
-      NOTE:
-      The precedence order of the various file locking control mechanisms is:
-
-        1) HDF5_USE_FILE_LOCKING environment variable (highest)
-
-        2) H5Pset_file_locking()
-
-        3) configure/CMake options (which set the property list defaults)
-
-        4) library defaults (currently best-effort)

     - Refactored public exposure of haddr_t type in favor of "object tokens"
 
-      To better accommodate HDF5 VOL connectors where "object addresses in a file"
-      may not make much sense, the following changes were made to the library:
-
-      * Introduced new H5O_token_t "object token" type, which represents a
-        unique and permanent identifier for referencing an HDF5 object within
-        a container; these "object tokens" are meant to replace object addresses.
-        Along with the new type, a new H5Oopen_by_token API call was introduced
-        to open an object by a token, similar to how object addresses were
-        previously used with H5Oopen_by_addr.
-
-      * Introduced new H5Lget_info2, H5Lget_info_by_idx2, H5Literate2, H5Literate_by_name2,
-        H5Lvisit2 and H5Lvisit_by_name2 API calls, along with their associated H5L_info2_t
-        struct and H5L_iterate2_t callback function, which work with the newly-introduced
-        object tokens, instead of object addresses. The original functions have been
-        renamed to version 1 functions and are deprecated in favor of the new version 2
-        functions. The H5L_info_t and H5L_iterate_t types have been renamed to version 1
-        types and are now deprecated in favor of their version 2 counterparts. For each of
-        the functions and types, compatibility macros take place of the original symbols.
-

-        two object tokens, convert an object token into a nicely-readable string format and
-        to convert an object token string back into a real object token, respectively.

-
-      It was reported that the reading of attributes with variable length string
-      datatype will crash with segmentation fault particularly when the number of

-      pointer was already closed when the attribute was accessed.

-    - Fixed an assertion failure in the parallel library when collectively
-      filling chunks. As it is required that chunks be written in
-      monotonically non-decreasing order of offset in the file, this assertion
-      was being triggered when the list of chunk file space allocations being
-      passed to the collective chunk filling routine was not sorted according

-
-      It was reported that the selection of every 10th element from a 20G

-      There was an assertion failure when moving meessages from running a

-
-    - Fixed the test failure from test_metadata_read_retry_info() in
-      test/swmr.c
-
-      The test failure is due to the incorrect number of bins returned for
-      retry info (info.nbins).  The # of bins expected for 101 read attempts
-      is 3 instead of 2.  The routine H5F_set_retries() in src/H5Fint.c
-      calculates the # of bins by first obtaining the log10 value for
-      (read attempts - 1).  For PGI/19, the log10 value for 100 read attempts
-      is 1.9999999999999998 instead of 2.00000.  When casting the log10 value
-      to unsigned later on, the decimal part is chopped off causing the test
-      failure.

-    - Fixed an issue where creating a file with non-default file space info
-      together with library high bound setting to H5F_LIBVER_V18.
-
-      When setting non-default file space info in fcpl via
-      H5Pset_file_space_strategy() and then creating a file with
-      both high and low library bounds set to
-      H5F_LIBVER_V18 in fapl, the library succeeds in creating the file.
-      File creation should fail because the feature of setting non-default
-      file space info does not exist in library release 1.8 or earlier.
-
-      This was fixed by setting and checking the proper version in the
-      file space info message based on the library low and high bounds
-      when creating and opening the HDF5 file.

-      dataset to a file created with both high and low library bounds set to

-    - A bug was discovered in the parallel library where an application
-      would hang if a collective read/write of a chunked dataset occurred
-      when collective metadata reads were enabled and some of the ranks
-      had no selection in the dataset's dataspace. The ranks which had no
-      selection in the dataset's dataspace called H5D__chunk_addrmap() to
-      retrieve the lowest chunk address in the dataset. This is because we
-      require reads/writes to be performed in strictly non-decreasing order
-      of chunk address in the file.
+        In debug builds of the library, this can cause asserts to trip. In
+        non-debug builds, it will produce normal library errors.
 
-      When the chunk index used was a version 1 or 2 B-tree, these
-      non-participating ranks would issue a collective MPI_Bcast() call
-      that the participating ranks would not issue, causing the hang. Since
-      the non-participating ranks are not actually reading/writing anything,
-      the H5D__chunk_addrmap() call can be safely removed and the address used
-      for the read/write can be set to an arbitrary number (0 was chosen).
+        The new library behavior is for H5Sset_extent_none() to convert
+        the dataspace into one of type H5S_NULL, which is better handled

-      File locking is used when files are opened to enforce SWMR semantics. A

-      HDF5_USE_FILE_LOCKING environment variable is set to the string "FALSE".
-      flock(2) is preferentially used, with fcntl(2) locks as a backup if
-      flock(2) is unavailable on a system (if neither is available, the lock
-      operation fails). On these systems, the file lock will often fail, which

-      have H5_HAVE_FCNTL defined but not H5_HAVE_FLOCK in the configure output.
+        A check for reading pass the end of the buffer was added to multiple

-      (DER - 2019/08/27, HDFFV-10892)
+        It was reported that the reading of attributes with variable length string
+        datatype will crash with segmentation fault particularly when the number of
+        threads is high (>16 threads).  The problem was due to the file pointer that
+        was set in the variable length string datatype for the attribute.  That file
+        pointer was already closed when the attribute was accessed.
 
-    - Torn pread/pwrite I/O would result in read and write corruption.
+        The problem was fixed by setting the file pointer to the current opened file pointer
+        when the attribute was accessed.  Similar patch up was done before when reading
+        dataset with variable length string datatype.
 
-      In the sec2, log, and core (with backing store) virtual file drivers
-      (VFDs), the read and write calls incorrectly reset the offset parameter
-      on torn pread and pwrite operations (i.e., I/O operations which fail to
-      be written atomically by the OS). For this bug to occur, pread/pwrite
-      have to be configured (this is the default if they are present on the
-      system) and the pread/pwrite operation has to fail to transfer all
-      the bytes, resulting in a multiple pread/pwrite calls.

-    - A bug was discovered in the parallel library which caused partial
-      parallel reads of filtered datasets to return incorrect data. The
-      library used the incorrect dataspace for each chunk read, causing
-      the selection used in each chunk to be wrong.
-
-      The bug was not caught during testing because all of the current
-      tests which do parallel reads of filtered data read all of the data
-      using an H5S_ALL selection. Several tests were added which exercise
-      partial parallel reads.

-    - A bug was discovered in the parallel library which caused parallel
-      writes of filtered datasets to trigger an assertion failure in the
-      file free space manager.
-
-      This occurred when the filter used caused chunks to repeatedly shrink
-      and grow over the course of several dataset writes. The previous chunk
-      information, such as the size of the chunk and the offset in the file,
-      was being cached and not updated after each write, causing the next write
-      to the chunk to retrieve the incorrect cached information and run into
-      issues when reallocating space in the file for the chunk.

-
-    - A bug was discovered in the parallel library which caused the
-      H5D__mpio_array_gatherv() function to allocate too much memory.
-
-      When the function is called with the 'allgather' parameter set
-      to a non-true value, the function will receive data from all MPI
-      ranks and gather it to the single rank specied by the 'root'
-      parameter. However, the bug in the function caused memory for
-      the received data to be allocated on all MPI ranks, not just the
-      singular rank specified as the receiver. In some circumstances,
-      this would cause an application to fail due to the large amounts
-      of memory being allocated.

-    - If an HDF5 file contains a malformed compound datatype with a
-      suitably large offset, the type conversion code can run off
-      the end of the type conversion buffer, causing a segmentation
-      fault.
-
-      This issue was reported to The HDF Group as issue #CVE-2017-17507.
-
-      NOTE: The HDF5 C library cannot produce such a file. This condition
-            should only occur in a corrupt (or deliberately altered) file
-            or a file created by third-party software.

-      THE HDF GROUP WILL NOT FIX THIS BUG AT THIS TIME
-
-      Fixing this problem would involve updating the publicly visible
-      H5T_conv_t function pointer typedef and versioning the API calls
-      which use it. We normally only modify the public API during
-      major releases, so this bug will not be fixed at this time.

-    - Inappropriate linking with deprecated MPI C++ libraries
-
-      HDF5 does not define *_SKIP_MPICXX in the public headers, so applications
-      can inadvertently wind up linking to the deprecated MPI C++ wrappers.
-
-      MPICH_SKIP_MPICXX and OMPI_SKIP_MPICXX have both been defined in H5public.h
-      so this should no longer be an issue. HDF5 makes no use of the deprecated
-      MPI C++ wrappers.

-    Configuration
-    -------------
-    - Applied patches to address Cywin build issues
-
-      There were three issues for Cygwin builds:
-      - Shared libs were not built.
-      - The -std=c99 flag caused a SIG_SETMASK undeclared error.
-      - Undefined errors when buildbing test shared libraries.
-
-      Patches to address these issues were received and incorporated in this version.

-    - Moved the location of gcc attribute.
-
-      The gcc attribute(no_sanitize), named as the macro HDF_NO_UBSAN,
-      was located after the function name. Builds with GCC 7 did not
-      indicate any problem, but GCC 8 issued errors. Moved the
-      attribute before the function name, as required.

-    - Reworked java test suite into individual JUnit tests.
+    - h5repack was fixed to repack the reference attributes properly.
 
-      Testing the whole suite of java unit tests in a single JUnit run
-      made it difficult to determine actual failures when tests would fail.
-      Running each file set of tests individually, allows individual failures
-      to be diagnosed easier. A side benefit is that tests for optional components
-      of the library can be disabled if not configured.
+        The code line that checks if the update of reference inside a compound
+        datatype is misplaced outside the code block loop that carries out the
+        check. In consequence, the next attribute that is not the reference
+        type was repacked again as the reference type and caused the failure of
+        repacking. The fix is to move the corresponding code line to the correct
+        code block.
