     Configuration:
     -------------
-    - 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:

-
-      (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

     Library:
     --------
-    - 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.
-
-      See the configure option discussion for HDFFV-11092 (above) for more

-
-    - 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.

-
-      When a buffer overflow occurred because a name length was corrupted
-      and became very large, h5dump crashed on memory access violation.

-    - 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.

-    - 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.

-
-    - 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.

-      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

-    - 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.

-
-    - 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.

-
-    - 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.

-
-    - 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.

     Tools
     -----
-    - The tools library was updated by standardizing the error stack process.
-
-      General sequence is:
-          h5tools_setprogname(PROGRAMNAME);
-          h5tools_setstatus(EXIT_SUCCESS);
-          h5tools_init();

-
-    - 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.

-          0 : Identical to '-v' or '--verbose'
-          1 : All level 0 information plus one-line attribute status summary

-      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

         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.
