* Tweaked a few API functions to use 'size_t' instead of 'unsigned' or
'hsize_t', which may cause errors in some cases.
+ * Fixed a bug of H5pubconf.h causing repeated definitions if it is included
+ more than once. hdf5.h now includes H5public.h which includes
+ H5pubconf.h. Applications should #include hdf5.h which handles multiple
+ inclusion correctly.
+ * Fixed H5FDmpio.h to be C++ friendly by making Parallel HDF5 API's to be
+ external to C++.
+ * Fixed a bug in H5FD_mpio_flush() that might result in negative file seek
+ if both MPIO and Split-file drivers are used together.
+ * Added new parallel hdf5 tests in t_mpi. The new test checks if the
+ filesystem or the MPI-IO can really handle greater than 2GB files.
+ If it fails, it prints information message only without failing the
+ test.
+ * Fixed a bug when reading chunked datasets where the edge of the dataset
+ would be incorrectly detected and generate an assertion failure.
+ * Fixed a bug where reading an entire dataset wasn't being handled
+ optimally when the dataset had unlimited dimensions. Dataset is read
+ in a single low-level I/O now, instead of being broken into separate
+ pieces internally.

New Features
============
+ * A helper script called ``h5cc'', which helps compilation of HDF5
+ programs, is now distributed with HDF5. See the reference manual

Pablo Performance Caputure Facility.
* Improved regular hyperslab I/O by about a factor of 6 or so.
+ * Added two simple parallel performance tests as mpi-perf.c (MPI
+ performance) and perf.c (PHDF5 performance) in testpar.
+ * Added a parallel HDF5 example examples/ph5example.c to illustrate
+ the basic way of using parallel HDF5.
+ * Added a new public macro, H5_VERS_INFO, which is a string holding
+ the HDF5 library version information. This string is also compiled
+ into all HDF5 binary code which helps to identify the version
+ information of the binary code. One may use the Unix strings
+ command on the binary file and looks for the pattern "HDF5 library
+ version".
+ * Added new checking in H5check_version() to verify the five HDF5 version
+ information macros (H5_VERS_MAJOR, H5_VERS_MINOR, H5_VERS_RELEASE,
+ H5_VERS_SUBRELEASE and H5_VERS_INFO) are consistent.
+ * Added perform programs to test the HDF5 library performance. Programs
+ are installed in directory perform/.
+ * The H5Pset_fapl_split() accepts raw and meta file names similar to the
+ syntax of H5Pset_fapl_multi() in addition to what it used to accept.
+ * Added a new test to verify the information provided by the configure
+ command.
+ * As part of the transition to using generic properties everywhere, the
+ parameter of H5Pcreate changed from H5P_class_t to hid_t, as well
+ the return type of H5Pget_class changed from H5P_class_t to hid_t.
+ Further changes are still necessary and will be documented here as they
