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 |
