Hello everyone,
1. A second pre-release version of HDF5 1.10.1 is available for testing and can be downloaded at the link below. This version will build in production mode by default. Changes since the pre1 version include the inclusion of complete HDF5 1.8 release history files in the release_docs directory and the addressing of a problem with collective metadata writes which caused CGNS tests with MPICH 3.1.4 to fail (HDFFV-10055<https://jira.hdfgroup.org/browse/HDFFV-10055>).

Four new features are introduced in HDF5 1.10.1:
Metadata Cache Image
Metadata Cache Evict on Close
Paged Aggregation
Page Buffering
Details and documentation for these features may be found at https://support.hdfgroup.org/HDF5/docNewFeatures/index.html.
For more information about the release see https://gamma.hdfgroup.org/ftp/pub/outgoing/hdf5/hdf5-1.10.1-pre2-RELEASE.txt
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 "development". Use the "--enable-production" configure flag if you want to build HDF5 in the production mode. The default will be changed to "production" in the next release candidate and in the release itself, which we hope to complete well before the end of April.
The shared library version numbers for lib.so.* files in HDF5-1.10.1 have been updated according to libtool's versioning system and the changes in symbols from HDF5-1.10.0-patch1. The API compatibility report is at this link: https://gamma.hdfgroup.org/ftp/pub/outgoing/hdf5/hdf5-1.10.1-pre1_interface_compatibility_report.
Your prompt reports of any issues found will be invaluable and very much appreciated. We expect to make the final HDF5 1.10.1 release available before the end of April. Thank you and happy testing!
Larry
