Fix for HDF5 1.8.5 Problem Affecting Files with Non-default Address and Length Sizes
A problem was discovered in HDF5 1.8.5 that affects files with non-default sizes of addresses and lengths as set by H5Pset_sizes(). The problem occurs when (sizeof_addr + 2*sizeof_size) is not a multiple of 8, unless using the new file format (H5Pset_libver_bounds()). Files created under these conditions by 1.8.5 will be readable by 1.8.5 but not by any other version of HDF5. Files created under these conditions by other versions of HDF5 will not be readable by 1.8.5.
We recommend that those who use H5Pset_sizes or may deal with files that use this feature move to the latest snapshot (snap4) of HDF5 1.8.5. If you have files created by 1.8.5 under these conditions that you wish to keep, you can fix this problem by using "h5repack -L" with the 1.8.5 version of h5repack to recreate the file with the new file format. You can then read this file with any version since 1.8.0, and if desired use h5repack (without -L) again to move back to the old file format.
The HDF5 1.8.5 Snapshot 4 software can be obtained from here:

Next release of HDF5, H4toH5 and HDF-Java 2.7
The Fall release of HDF5 1.8.6, the HDF-Java Products 2.7, and h4h5tools 2.1.2 will occur in mid-October this year. Maintenance releases of HDF5 typically occur in May and November, but will be early this year, due to an in-house move.
