Dec. 1, 2017 — The HDF5-1.8.20 release is now available. It can be obtained from The HDF Group Support Download page: https://support.
It can also be obtained directly from: https://support.
HDF5-1.8.20 is a minor release with a few new features and changes. Important changes include:
- An issue with H5Zfilter_avail was fixed where it was not finding available plugins.
- Improvements were made to the h5repack, h5ls, h5dump, h5diff, and h5import utilities.
In particular, please be aware that the behavior of the h5repack utility changed.
A parameter was added to the “UD=” option of h5repack to allow the user defined filter flag to be changed to either H5Z_FLAG_MANDATORY (0) orH5Z_FLAG_OPTIONAL (1).
An example of the command with the new parameter is shown here:
h5repack -f UD=307,0,1,9 h5repack_layout.h5 out.h5repack_layout.h5
Previously, the command would have been:
h5repack -f UD=307,1,9 h5repack_layout.h5 out.h5repack_layout.h5
- Support for the NAG compiler was added.
- Many C++ APIs were added or modified to better reflect the HDF5 model.

Changes that affect maintainers of HDF5-dependent applications are listed on the HDF5 Software Changes from Release to Release page.
