+
+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.
+
+      (VC - 2017/05/02, HDFFV-9934)
+
+
+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
+    in the HDF5 source. Please report any new problems found to
+    help@hdfgroup.org.

 ============
 
-    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.

+    Tools
+    -----
+    - h5diff
 
-    - H5Dget_chunk_storage_size
+      h5diff has new option enable-error-stack.
 
-      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.
+      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.
 
-      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.

     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)
+    - 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)

+
+      (HDFFV-10037, MSB, 2017/10/21)
+
+    - cmake
+
+      Too many commands for POST_BUILD step caused command line to be

     Library
     -------
-    - bitfield datatypes
+    - 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)
 
-      bitfield datatypes did not fully support endianness of the data.
+    - Fix rare object header corruption bug
 
-      Improved the endianness of bitfield datatypes by adding missing functional
-      code. This code used integer types as a template.
+      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)
 
-    - Newly created datasets with H5D_COMPACT layout failed to open after 
-      several H5Dopen/H5Dclose cycles.
+    - H5Zfilter_avail in H5Z.c
 
-      The layout "dirty" flag for a compact dataset is now properly reset 
-      before flushing the message.
+      The public function checked for plugins, while the private
+      function did not.

+      Moved check for plugin from public to private function. Updated
+      H5P__set_filter due to change in H5Z_filter_avail. Updated tests.
 
-    - Missing #ifdef __cplusplus macros were added to the generated H5Epubgen.h file.

-      h5repack did not maintain the creation order flag of the root
-      group.
+      h5repack failed to copy a dataset with existing filter.
 
-      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.
+      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.

+      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

+      h5repack always set the User Defined filter flag to H5Z_FLAG_MANDATORY.
 
-      Improved h5diff compare of strings and arrays by adding a check for
-      string lengths and if the strpad was null filled.
+      Added another parameter to the 'UD=' option to set the flag by default

     - h5diff
 
-      h5diff did not report user-defined filter data differences correctly.
+      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)
 
-      Improved h5diff compare of user-defined filter data by reporting an
-      error if the user-defined filter plugin cannot be found.
+    - 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.
