Important changes include: o The "can't insert duplicate key" issue that occurred in HDF5-1.8.13 has been resolved. A new internal structure had been introduced in anticipation for handling 64-bit object identifiers in a future release. An unanticipated side-effect of this new structure was that when objects were closed, the memory was not being properly freed. Applications that open and close many objects and which use HDF5-1.8.13 should be moved to HDF5-1.8.14. o The shared library version number (soname) changed due to renamed symbols in H5Ppublic.h. o CMake 3.* is required in this release. o Several issues with string handling were resolved in the HDF5 High-level APIs. This release contains many other changes that are not listed here. Please be sure to read the Release Notes for a comprehensive list of new features and changes: http://www.hdfgroup.org/ftp/HDF5/current/src/hdf5-1.8.14-RELEASE.txt Changes that affect maintainers of HDF5-dependent applications are listed on the HDF5 Software Changes from Release to Release page.

Book Release: "High Performance Parallel I/O" ============================================ "High Performance Parallel I/O" was released at the end of October.
