Hello everyone,
A pre-release version of HDF5 1.10.6 source is available for testing and can be downloaded at the following link:
https://gamma.hdfgroup.org/ftp/pub/outgoing/hdf5
A brief summary of new features introduced in HDF5 1.10.6:
- Improved performance when creating a large number of small datasets.
- CMake: added support for VS2019. Requires CMake version 3.15 on Windows. Otherwise CMake on Windows requires CMake
version 3.13 or later. Other platforms require CMake version 3.10 or later.
- Added CMake options to disable building of static libraries.
- Added configure options to enable/disable building tests and tools.
- Several bugs were fixed.
For details about these and other changes or more information about the release see https://gamma.hdfgroup.org/ftp/pub/outgoing/hdf5/hdf5-1.10.6-pre1-RELEASE.txt or https://portal.hdfgroup.org/display/HDF5/Software+Changes+from+Release+to+Release+for+HDF5-1.10.
If you have time to test this release candidate, we would greatly appreciate it. We test HDF5 on a variety of platforms and with multiple compilers, but there is always a system that we couldn’t test on. Your feedback is critical.
For those who use autoconf to build HDF5, please notice that the default configuration mode for this distribution is “–enable-build-mode=production". Use the “–enable-build-mode=debug” configure flag if you want to build HDF5 in the debug mode. Testing in both modes is recommended when possible.
The shared library version numbers for lib.so.* files in HDF5-1.10.6-pre1 have been updated according to libtool’s versioning system and the changes in symbols from HDF5-1.10.5. The API compatibility report is at this link: https://gamma.hdfgroup.org/ftp/pub/outgoing/hdf5/hdf5-1.10.6-pre1-vs.1.10.5-preliminary-interface_compatibility_report.html.
Your prompt reports of any issues found will be invaluable and very much appreciated. Thank you and happy testing!
