Library
-------
* Fixed bug in parallel I/O routines where a collective I/O which used
MPI derived types, followed by an independent I/O would cause the library
to hang. QAK 2002/06/24
* Fixed bug in chunking routines where they were using internal allocation
free routines, instead of malloc/free, preventing user filters from
working correctly. Chunks are now allocated/freed with malloc/free and
so should the chunks in user filters. QAK 2002/06/18
* Fixed bug where regular hyperslab selection could get incorrectly
transferred when the number of elements in a row did not fit evenly
into the buffer provided. QAK 2002/06/12
* Fixed bug (#499) which allowed an "empty" compound or enumerated datatype
(one with no members) to be used to create a dataset or committed to a
file. QAK - 2002/06/11
* Fixed bug (#777) which allowed a compound datatype to be inserted into
itself. QAK - 2002/06/10
* Fixed bug (#789) where creating 1-D dataset region reference caused the
library to go into infinite loop. QAK - 2002/06/10
* Fixed bug (#699, fix provided by a user) where a scalar dataspace was
written to the file and then subsequently queried with the
H5Sget_simple_extent_type function, type was reported H5S_SIMPLE instead
of H5S_SCALAR. EIP - 2002/06/04
* Clear symbol table node "dirty" flag when flushing symbol tables to
disk, to reduce I/O calls made & improve performance. QAK - 2002/06/03
* Fixed bug where an object's header could get corrupted in certain obscure
situations where many objects were created in the file. QAK - 2002/05/31
* Fixed bug where read/write intent in file IDs created with H5Freopen

New Features
============
* Added environment variable flag to control whether creating MPI derived
typed is preferred or not. This can affect performance, depending on
which way the MPI-I/O library is optimized for. The default is set to
prefer MPI derived types for collective raw data transfers, setting the
HDF5_MPI_PREFER_DERIVED_TYPES environment variable to "0" (i.e.:
"setenv HDF5_MPI_PREFER_DERIVED_TYPES 0") changes the preference to avoid
using then whenever possible. QAK - 2002/06/19
* Changed MPI I/O routines to avoid creating MPI derived types (and thus
needing to set the file view) for contiguous selections within datasets,
which should result in some performance improvement for those types of
selections. QAK - 2002/06/18
* Enable MPI type support for collective I/O to be enabled by default.
This can be disabled by setting the HDF5_MPI_OPT_TYPES environment
variable to the value "0". QAK - 2002/06/14
* Allow chunks in chunked datasets to be cached when parallel file is
opened for read-only access (bug #709). QAK - 2002/06/10
* Added internal "small data" aggregation, which can reduce the number of
actual I/O calls made, improving performance. QAK - 2002/06/05
* Improved internal metadata aggregation, which can reduce the number of
actual I/O calls made, improving performance. Additionally, this can
reduce the size of files produced. QAK - 2002/06/04
* Improved internal metadata caching, which can reduce the number of actual
I/O calls made by a substantial amount, improving
performance. QAK - 2002/06/03
* Added 'closing' parameter to VFL 'flush' callback function and H5FDflush.
This allows the library to indicate that the file will be closed
immediately following the call to 'flush' and can be used to avoid actions
