HDF5-1.2.1 binaries and updated Web pages will be available after the New Year without further notice.

Bug fixes since HDF5-1.2.0

Configuration

• The hdf5.h include file was fixed to allow the HDF5 Library to be compiled with other libraries/applications that use GNU autoconf.

• Configuration for parallel HDF5 was improved. Configure now attempts to link with libmpi.a and/or libmpio.a as the MPI libraries by default. It also uses "mpirun" to launch MPI tests by default. It tests to link MPIO routines during the configuration stage, rather than failing later as before. One can just do "./configure --enable-parallel" if the MPI library is in the system library.

Dataset region references

• Error was fixed which was not allowing dataset region references to have their regions retrieved correctly.

Tools

• Added an option, -V, to show the version information of h5dump.

• Fixed a core dumping bug of h5toh4 when executed on platforms like TFLOPS.

• The test script for h5toh4 used to not able to detect the hdp dumper command was not valid. It now detects and reports the failure of hdp execution.

Documentation

• User's Guide and Reference Manual were updated. See http://hdf.ncsa.uiuc.edu/HDF5/doc/PSandPDF/index.html for more details.
