The tar ball contains fixes for a few CMake problems reported on FORUM for the previous release candidate. Specifically, the requested enhancement for building parallel HDF5 with CMake has been addressed.

-"Dynamically loaded filters in HDF5" will allow to load a compression library at run time. With this feature the users will be able to use
the HDF5 library and tools distributed by The HDF Group with the thrid-party HDF5 compression methods (and other filters).
The document that describes the feature and the BZI2 plugin example is available from
If you have some time to test this pre-release, we would greatly appreciate it. Newly reported issues will be documented and will be addressed in the next release.
The HDF Group
