+
+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.
