The original VOL API is - now considered deprecated and VOL users and connector authors should - target the 1.14 VOL API. - - The specific changes are too extensive to document in a release note, so - VOL users and connector authors should consult the updated VOL connector - author's guide and the 1.12-1.14 VOL migration guide. - - (DER - 2022/12/28) - - - H5VLquery_optional() signature change - - The last parameter of this API call has changed from a pointer to hbool_t - to a pointer to uint64_t. Due to the changes in how optional operations - are handled in the 1.14 VOL API, we cannot make the old API call work - with the new scheme, so there is no API compatibility macro for it. - - (DER - 2022/12/28) - - - H5I_free_t callback signature change - - In order to support asynchronous operations and future IDs, the signature - of the H5I_free_t callback has been modified to take a second 'request' - parameter. Due to the nature of the internal library changes, no API - compatibility macro is available for this change. - - (DER - 2022/12/28) - - - Fix for CVE-2019-8396 - - Malformed HDF5 files may have truncated content which does not match - the expected size.

Unfortunately, the heap canaries caused - problems when library memory operations were mixed with standard C - library memory operations (such as in the filter pipeline, where - buffers may have to be reallocated). Since any platform with a C - compiler also usually has much more sophisticated memory sanity - checking tools than the HDF5 library provided (e.g., valgrind), we - have decided to to remove the feature entirely. - - In addition to the configure changes described above, this also removes - the following from the public API: - H5get_alloc_stats() - H5_alloc_stats_t - - (DER - 2022/11/03) Parallel Library: ----------------- @@ -229,11 +130,7 @@ New Features Documentation: -------------- - - Ported the existing VOL Connector Author Guide document to doxygen. - - Added new dox file, VOLConnGuide.dox. - - (ADB - 2022/12/20) + - Support for new platforms, languages and compilers @@ -292,128 +189,6 @@ Bug Fixes since HDF5-1.13.3 release (JTH - 2023/02/16, GH #2433) - - Seg fault on file close - - h5debug fails at file close with core dump on a file that has an - illegal file size in its cache image.

This eventually causes assertion failure in - H5VL__native_file_close() when the library finally exits and tries to - access that file object in the table for closing. - - The closing routine, H5F_dest(), will not free the file structure if - there is error, keeping a valid file structure in the ID node table. - It will be freed later in H5VL__native_file_close() when the - library exits and terminates the file package. - - (VC - 2022/12/14, HDFFV-11052, CVE-2020-10812) - - - Fix CVE-2018-13867 / GHSA-j8jr-chrh-qfrf - - Validate location (offset) of the accumulated metadata when comparing. - - Initially, the accumulated metadata location is initialized to HADDR_UNDEF - - the highest available address. Bogus input files may provide a location - or size matching this value. Comparing this address against such bogus - values may provide false positives.
