+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.

+
+    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.

+
+    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()

+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.

     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.

     -------
-    - 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.

     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.
