HDF5 1.8.17-pre1 release candidate is available for testing

Hello everyone,

A pre-release candidate version of HDF5 1.8.17 is available for testing and can be downloaded at the following link:


This is a maintenance release that has several bug fixes. For more information see https://gamma.hdfgroup.org/ftp/pub/outgoing/hdf5/hdf5-1.8.17-pre1-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 the release itself.

The shared library version numbers for lib.so.* files in HDF5-1.8.17-pre1 have been updated according to libtool's versioning system and the changes in symbols from HDF5-1.8.16. The API compatibility report is at this link: https://gamma.hdfgroup.org/ftp/pub/outgoing/hdf5/interface_compatibility_report_hdf5-1.8.17-pre1. The effect on the numbers from HDF5-1.8.16 to HDF5-1.8.17-pre1 was to increase libhdf5.so.10.1.0 to libhdf5.so.10.2.0, libhdf5_hl.so.10.0.2 to libhdf5_hl.so.10.1.0, libhdf5_cpp.so.11.0.0 to libhdf5_cpp.so.12.0.0, libhdf5_hl_cpp.so.11.0.0 to libhdf5_hl_cpp.so.11.1.0, and all other wrapper library files from libhdf5*.so.10.0.2 to libhdf5*.so.10.0.3.

Your reports will be invaluable and very much appreciated. Thank you and happy testing!
