Release of HDF5-1.8.20
The HDF5-1.8.20 release is now available. It can be obtained from The HDF Group Support Download page:
https://support.hdfgroup.org/downloads/
It can also be obtained directly from:
https://support.hdfgroup.org/HDF5/release/obtain518.html
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) or H5Z_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.
This release contains many other changes that are not listed here. Please be sure to read the https://support.hdfgroup.org/ftp/HDF5/releases/hdf5-1.8/hdf5-1.8.20/src/hdf5-1.8.20-RELEASE.txt for a comprehensive list of new features and changes.
