This release contains many important new features and changes, including:

• HDF5 now supports building with the AEC library as a replacement library for SZip.
• CVE-2018-13870, CVE-2018-13869 and CVE-2018-17435 were fixed in this release.
• Metadata cache optimization was added to improve performance.
• A CMake option was added to link generated Fortran MOD files into the include directory.
• Autotools and CMake options were added to enable or disable file locking. C functions and C++, Fortran and Java wrappers were also added for setting and getting the file locking parameters.
• The Splitter VFD was added. It maintains separate R/W and W/O channels for ”concurrent” file writes to two files using a single HDF5 file handle.
• The Mirror VFD was added. It uses TCP/IP sockets to perform write-only (W/O) file I/O on a remote machine.
• Several hyperslab selection functions were added in this release.
• Internal memory sanity checking was disabled in Autotools debug builds by default. The sanity checking replaced C API malloc(3) and free(3) calls with HDF5 internal calls, which caused problems with the external filter plugins.
• Several tools issues were fixed (h5diff, h5repack).
• The High Level H5DSis_scale function was fixed to correctly handle CLASS and DIMENSION_SCALE attributes that were not written according to the Dimension Scales Specification.
