-    - CMake will now run the shell script tests in test/ by default
-
-      The test directory includes several shell script tests that previously
-      were not run by CMake. These are now run by default. TEST_SHELL_SCRIPTS
-      has been set to ON and SH_PROGRAM has been set to bash (some test
-      scripts use bash-isms). Platforms without bash (e.g., Windows) will
-      ignore the script tests.

-    - Added a configure-time option to control certain compiler warnings
-      diagnostics
-
-      A new configure-time option was added that allows some compiler warnings
-      diagnostics to have the default operation. This is mainly intended for
-      library developers and currently only works for gcc 10 and above. The
-      diagnostics flags apply to C, C++ and Fortran compilers and will appear
-      in "H5 C Flags", H5 C++ Flags" and H5 Fortran Flags, respectively. They
-      will NOT be exported to h5cc, etc.
-
-      The default is OFF, which will disable the warnings URL and color attributes
-      for the warnings output. ON will not add the flags and allow default behavior.

-    - CMake option to build the HDF filter plugins project as an external project
-
-        The HDF filter plugins project is a collection of registered compression
-        filters that can be dynamically loaded when needed to access data stored
-        in a hdf5 file. This CMake-only option allows the plugins to be built and
-        distributed with the hdf5 library and tools. Like the options for szip and
-        zlib, either a tgz file or a git repository can be specified for the source.
-
-        The option was refactored to use the CMake FetchContent process. This allows
-        more control over the filter targets, but required external project command
-        options to be moved to a CMake include file, HDF5PluginCache.cmake. Also
-        enabled the filter examples to be used as tests for operation of the
-        filter plugins.

-
-    - FreeBSD Autotools configuration now defaults to 'cc' and 'c++' compilers
-
-      On FreeBSD, the autotools defaulted to 'gcc' as the C compiler and did
-      not process C++ options. Since FreeBSD 10, the default compiler has
-      been clang (via 'cc').
-
-      The default compilers have been set to 'cc' for C and 'c++' for C++,
-      which will pick up clang and clang++ respectively on FreeBSD 10+.
-      Additionally, clang options are now set correctly for both C and C++
-      and g++ options will now be set if that compiler is being used (an
-      omission from the former functionality).

-
-    - Fixed POSIX problems when building w/ gcc on Solaris
-
-      When building on Solaris using gcc, the POSIX symbols were not
-      being set correctly, which could lead to issues like clock_gettime()
-      not being found.
-
-      The standard is now set to gnu99 when building with gcc on Solaris,
-      which allows POSIX things to be #defined and linked correctly. This
-      differs slightly from the gcc norm, where we set the standard to c99
-      and manually set POSIX #define symbols.

-      (DER - 2020/11/25, HDFFV-11191)
-
-    - Added a configure-time option to consider certain compiler warnings
-      as errors
-
-      A new configure-time option was added that converts some compiler warnings
-      to errors. This is mainly intended for library developers and currently
-      only works for gcc and clang. The warnings that are considered errors
-      will appear in the generated libhdf5.settings file. These warnings apply
-      to C and C++ code and will appear in "H5 C Flags" and H5 C++ Flags",
-      respectively. They will NOT be exported to h5cc, etc.
-
-      The default is OFF. Building with this option may fail when compiling
-      on operating systems and with compiler versions not commonly used by
-      the library developers. Compilation may also fail when headers not
-      under the control of the library developers (e.g., mpi.h, hdfs.h) raise
-      warnings.

-          PLUGIN_TGZ_NAME or PLUGIN_GIT_URL
-        There are more options necessary for various filters and the plugin project

     Library:
     --------
-    - Change how the release part of version, in major.minor.release is checked
-      for compatibility
-
-      The HDF5 library uses a function, H5check_version, to check that
-      the version defined in the header files, which is used to compile an
-      application is compatible with the version codified in the library, which
-      the application loads at runtime. This previously required an exact match
-      or the library would print a warning, dump the build settings and then
-      abort or continue. An environment variable controlled the logic.
-
-      Now the function first checks that the library release version, in
-      major.minor.release, is not older than the version in the headers.
-      Secondly, if the release version is different, it checks if either
-      the library version or the header version is in the exception list, in
-      which case the release part of version, in major.minor.release, must
-      be exact. An environment variable still controls the logic.
-
-        (ADB - 2021/07/27)
-
-    - H5Gcreate1() now rejects size_hint parameters larger than UINT32_MAX
-
-      The size_hint value is ultimately stored in a uint32_t struct field,
-      so specifying a value larger than this on a 64-bit machine can cause
-      undefined behavior including crashing the system.
-
-      The documentation for this API call was also incorrect, stating that
-      passing a negative value would cause the library to use a default
-      value. Instead, passing a "negative" value actually passes a very large
-      value, which is probably not what the user intends and can cause
-      crashes on 64-bit systems.
-
-      The Doxygen documentation has been updated and passing values larger
-      than UINT32_MAX for size_hint will now produce a normal HDF5 error.
-
-        (DER - 2021/04/29, HDFFV-11241)
-
-
-    - H5Pset_fapl_log() no longer crashes when passed an invalid fapl ID
-
-      When passed an invalid fapl ID, H5Pset_fapl_log() would usually
-      segfault when attempting to free an uninitialized pointer in the error
-      handling code. This behavior is more common in release builds or
-      when the memory sanitization checks were not selected as a build
-      option.
-
-      The pointer is now correctly initialized and the API call now
-      produces a normal HDF5 error when fed an invalid fapl ID.
-
-        (DER - 2021/04/28, HDFFV-11240)
-
-    - Fixes a segfault when H5Pset_mdc_log_options() is called multiple times
-
-      The call incorrectly attempts to free an internal copy of the previous
-      log location string, which causes a segfault. This only happens
-      when the call is invoked multiple times on the same property list.
-      On the first call to a given fapl, the log location is set to NULL so
-      the segfault does not occur.
-
-      The string is now handled properly and the segfault no longer occurs.
-
-        (DER - 2021/04/27, HDFFV-11239)
-
-    - HSYS_GOTO_ERROR now emits the results of GetLastError() on Windows
-
-      HSYS_GOTO_ERROR is an internal macro that is used to produce error
-      messages when system calls fail. These strings include errno and the
-      the associated strerror() value, which are not particularly useful
-      when a Win32 API call fails.
-
-      On Windows, this macro has been updated to include the result of
-      GetLastError(). When a system call fails on Windows, usually only
-      one of errno and GetLastError() will be useful, however we emit both
-      for the user to parse. The Windows error message is not emitted as
-      it would be awkward to free the FormatMessage() buffer given the
-      existing HDF5 error framework. Users will have to look up the error
-      codes in MSDN.
-
-      The format string on Windows has been changed from:
-
-          "%s, errno = %d, error message = '%s'"
-
-      to:
-
-          "%s, errno = %d, error message = '%s', Win32 GetLastError() = %"PRIu32""
-
-      for those inclined to parse it for error values.
-
-        (DER - 2021/03/21)
-
-    - File locking now works on Windows
-
-      Since version 1.10.0, the HDF5 library has used a file locking scheme
-      to help enforce one reader at a time accessing an HDF5 file, which can
-      be helpful when setting up readers and writers to use the single-
-      writer/multiple-readers (SWMR) access pattern.
-
-      In the past, this was only functional on POSIX systems where flock() or
-      fcntl() were present. Windows used a no-op stub that always succeeded.
-
-      HDF5 now uses LockFileEx() and UnlockFileEx() to lock the file using the
-      same scheme as POSIX systems. We lock the entire file when we set up the
-      locks (by passing DWORDMAX as both size parameters to LockFileEx()).
-
-        (DER - 2021/03/19, HDFFV-10191)
-
-    - H5Epush_ret() now requires a trailing semicolon
-
-        H5Epush_ret() is a function-like macro that has been changed to
-        contain a `do {} while(0)` loop. Consequently, a trailing semicolon
-        is now required to end the `while` statement. Previously, a trailing
-        semi would work, but was not mandatory. This change was made to allow
-        clang-format to correctly format the source code.
-
-        (SAM - 2021/03/03)
-
-    - Improved performance of H5Sget_select_elem_pointlist
-
-        Modified library to cache the point after the last block of points
-        retrieved by H5Sget_select_elem_pointlist, so a subsequent call to the
-        same function to retrieve the next block of points from the list can
-        proceed immediately without needing to iterate over the point list.

-
-        Moved the perf and h5perf tools from tools/test/perform to

 Bug Fixes since HDF5-1.10.7 release
 ===================================
     Library
     -------
-    - Detection of simple data transform function "x"
-
-        In the case of the simple data transform function "x" the (parallel)
-        library recognizes this is the same as not applying this data transform
-        function. This improves the I/O performance. In the case of the parallel
-        library, it also avoids breaking to independent I/O, which makes it
-        possible to apply a filter when writing or reading data to or from
-        teh HDF5 file.
-
-        (JWSB - 2021/09/13)
-
-    - Fixed an invalid read and memory leak when parsing corrupt file space
-      info messages
-
-        When the corrupt file from CVE-2020-10810 was parsed by the library,
-        the code that imports the version 0 file space info object header
-        message to the version 1 struct could read past the buffer read from
-        the disk, causing an invalid memory read. Not catching this error would
-        cause downstream errors that eventually resulted in a previously
-        allocated buffer to be unfreed when the library shut down. In builds
-        where the free lists are in use, this could result in an infinite loop
-        and SIGABRT when the library shuts down.
-
-        We now track the buffer size and raise an error on attempts to read
-        past the end of it.
-
-        (DER - 2021/08/12, HDFFV-11053)
-
-    - Fixed CVE-2018-14460
-
-        The tool h5repack produced a segfault when the rank in dataspace
-        message was corrupted, causing invalid read while decoding the
-        dimension sizes.
-
-        The problem was fixed by ensuring that decoding the dimension sizes
-        and max values will not go beyong the end of the buffer.
-
-        (BMR - 2021/05/12, HDFFV-11223)
-
-    - Fixed CVE-2018-11206
-
-        The tool h5dump produced a segfault when the size of a fill value
-        message was corrupted and caused a buffer overflow.
-
-        The problem was fixed by verifying the fill value's size
-        against the buffer size before attempting to access the buffer.
-
-        (BMR - 2021/03/15, HDFFV-10480)
-
-    - Fixed CVE-2018-14033 (same issue as CVE-2020-10811)
-
-        The tool h5dump produced a segfault when the storage size message
-        was corrupted and caused a buffer overflow.
-
-        The problem was fixed by verifying the storage size against the
-        buffer size before attempting to access the buffer.

-
-    - Remove underscores on header file guards
-
-        Header file guards used a variety of underscores at the beginning of the define.
-
-        Removed all leading (some trailing) underscores from header file guards.
-
-        (ADB - 2021/03/03, #361)
+    - 
 
 
     Java Library
     ------------
-    - The H5FArray.java class, in which virtually the entire execution time
-        is spent using the HDFNativeData method that converts from an array
-        of bytes to an array of the destination Java type.
-
-        1. Convert the entire byte array into a 1-d array of the desired type,
-           rather than performing 1 conversion per row;
-        2. Use the Java Arrays method copyOfRange to grab the section of the
-           array from (1) that is desired to be inserted into the destination array.

+    - 
 
 
     Configuration
     -------------
-    - Corrected path searched by CMake find_package command
-
-      The install path for cmake find_package files had been changed to use
-        "share/cmake"
-      for all platforms. However the trailing "hdf5" directory was not removed.
-      This "hdf5" additional directory has been removed.
-
-      (ADB - 2021/09/27)
-
-    - Corrected pkg-config compile script
-
-      It was discovered that the position of the "$@" argument for the command
-      in the compile script may fail on some platforms and configurations. The
-      position of the "$@"command argument was moved before the pkg-config sub command.
-
-      (ADB - 2021/08/30)
-
-    - Fixed CMake C++ compiler flags
-
-      A recent refactoring of the C++ configure files accidently removed the
-      file that executed the enable_language command for C++ needed by the
-      HDFCXXCompilerFlags.cmake file. Also updated the intel warnings files,
-      including adding support for windows platforms.
-
-      (ADB - 2021/08/10)
-
-    - Autotools clang debug optimization level change
-
-      HDF5 1.10.7 erroneously sets the debug optimization level to "-g" when
-      building with clang via the Autotools. This has now been set to:
-
-        -Og     clang 4+ or Xcode 9+
-        -O1     otherwise
-
-      (DER - 2021/07/28, HDFFV-11192)
-    - Better support for libaec (open-source Szip library) in CMake
-
-      Implemented better support for libaec 1.0.5 (or later) library. This version
-      of libaec contains improvements for better integration with HDF5. Furthermore,
-      the variable USE_LIBAEC_STATIC has been introduced to allow to make use of
-      static version of libaec library. Use libaec_DIR or libaec_ROOT to set
-      the location in which libaec can be found.
-
-      Be aware, the Szip library of libaec 1.0.4 depends on another library within
-      libaec library. This dependency is not specified in the current CMake
-      configuration which means that one can not use the static Szip library of
-      libaec 1.0.4 when building HDF5. This has been resolved in libaec 1.0.5.
-
-      (JWSB - 2021/06/22)
-
-
-    - Refactor CMake configure for Fortran
-
-      The Fortran configure tests for KINDs reused a single output file that was
-      read to form the Integer and Real Kinds defines. However, if config was run
-      more then once, the CMake completed variable prevented the tests from executing
-      again and the last value saved in the file was used to create the define.
-      Creating separate files for each KIND solved the issue.
-
-      In addition the test for H5_PAC_C_MAX_REAL_PRECISION was not pulling in
-      defines for proper operation and did not define H5_PAC_C_MAX_REAL_PRECISION
-      correctly for a zero value. This was fixed by supplying the required defines.
-      In addition it was moved from the Fortran specific HDF5UseFortran.camke file
-      to the C centric ConfigureChecks.cmake file.
-
-      (ADB - 2021/06/03)
-
-    - Remove arbitrary warning flag groups from CMake builds
-
-      The arbitrary groups were created to reduce the quantity of warnings being
-      reported that overwhelmed testing report systems. Considerable work has
-      been accomplished to reduce the warning count and these arbitrary groups
-      are no longer needed.
-      Also the default for all warnings, HDF5_ENABLE_ALL_WARNINGS, is now ON.
-
-      Visual Studio warnings C4100, C4706, and C4127 have been moved to
-      developer warnings, HDF5_ENABLE_DEV_WARNINGS, and are disabled for normal builds.
-
-      (ADB - 2021/03/22, HDFFV-11228)
-
-    - Reclassify CMake messages, to allow new modes and --log-level option
-
-      CMake message commands have a mode argument. By default, STATUS mode
-      was chosen for any non-error message. CMake version 3.15 added additional
-      modes, NOTICE, VERBOSE, DEBUG and TRACE. All message commands with a mode
-      of STATUS were reviewed and most were reclassified as VERBOSE. The new
-      mode was protected by a check for a CMake version of at least 3.15. If CMake
-      version 3.17 or above is used, the user can use the command line option
-      of "--log-level" to further restrict which message commands are displayed.
-
-      (ADB - 2021/01/11, HDFFV-11144)
-
-    - Fixes Autotools determination of the stat struct having an st_blocks field
-
-      A missing parenthesis in an autoconf macro prevented building the test
-      code used to determine if the stat struct contains the st_blocks field.
-      Now that the test functions correctly, the H5_HAVE_STAT_ST_BLOCKS #define
-      found in H5pubconf.h will be defined correctly on both the Autotools and
-      CMake. This #define is only used in the tests and does not affect the
-      HDF5 C library.

     Tools
     -----
-    - Changed how h5dump and h5ls identify long double.
-
-        Long double support is not consistent across platforms. Tools will always
-        identify long double as 128-bit [little/big]-endian float nn-bit precision.
-        New test file created for datasets with attributes for float, double and
-        long double. In addition any unknown integer or float datatype will now
-        also show the number of bits for precision.
-        These files are also used in the java tests.
-
-        (ADB - 2021/03/24, HDFFV-11229)
-
-    - Fixed tools argument parsing.
-
-        Tools parsing used the length of the option from the long array to match
-        the option from the command line. This incorrectly matched a shorter long
-        name option that happened to be a subset of another long option.
-        Changed to match whole names.
