• [Windows] Bumped packaged HDF5 to 1.10.6, HDF4 to 4.2.14, and libcurl to 7.60.0.
• [Enhancement] Support has been added for HDF5-1.12.0. See [https://github.com//issues/1528].
• [Bug Fix] Correct behavior for the command line utilities when directly accessing a directory using utf8 characters. See Github #1669, Github #1668 and Github #1666 for more information.
• [Bug Fix] Attempts to set filters or chunked storage on scalar vars will now return NC_EINVAL. Scalar vars cannot be chunked, and only chunked vars can have filters. Previously the library ignored these attempts, and always storing scalars as contiguous storage. See [https://github.com//issues/1644].
• [Enhancement] Support has been added for multiple filters per variable. See [https://github.com//issues/1584].
• [Enhancement] Now nc_inq_var_szip retuns 0 for parameter values if szip is not in use for var. See [https://github.com//issues/1618].
• [Enhancement] Now allow parallel I/O with filters, for HDF5-1.10.3 and later. See [https://github.com//issues/1473].
• [Enhancement] Increased default size of cache buffer to 16 MB, from 4 MB. Increased number of slots to 4133. See [https://github.com//issues/1541].
• [Enhancement] Allow zlib compression to be used with parallel I/O writes, if HDF5 version is 1.10.3 or greater. See [https://github.com//issues/1580].
• [Enhancement] Restore use of szip compression when writing data (including writing in parallel if HDF5 version is 1.10.3 or greater). See [https://github.com//issues/1546].
• [Enhancement] Enable use of compact storage option for small vars in netCDF/HDF5 files. See [https://github.com//issues/1570].
• [Enhancement] Updated benchmarking program bm_file.c to better handle very large files. See [https://github.com//issues/1555].
• [Enhancement] Added version number to dispatch table, and now check version with nc_def_user_format(). See [https://github.com//issues/1599].
• [Bug Fix] Fixed user setting of MPI launcher for parallel I/O HDF5 test in h5_test. See [https://github.com//issues/1626].
• [Bug Fix] Fixed problem of growing memory when netCDF-4 files were opened and closed. See [https://github.com//issues/1575 and https://github.com//issues/1571].
• [Enhancement] Increased size of maximum allowed name in HDF4 files to NC_MAX_NAME. See [https://github.com//issues/1631].
