Library
-------
- * Fixed bug with contiguous hyperslabs not being detected, causing
- slower I/O than necessary.
- * Fixed bug where non-aligned hyperslab I/O on chunked datasets was
- causing errors during I/O
- * The RCSID string in H5public.h was causing the C++ compiling problem
- because when it was included multiple times, C++ did not like multiple
- definitions of the same static variable. All occurance of RCSID
- definition are removed since we have not used it consistently before.
- * Fixed bug with non-zero userblock sizes causing raw data to not write
- correctly.
- * Fixed build on Linux systems with --enable-static-exec flag. It now
- works correctly.
- * IMPORTANT: Fixed file metadata corruption bug which could cause metadata
- data loss in certain situations.
- * The allocation by alignment (H5Pset_alignment) feature code somehow
- got dropped in some 1.3.x version. Re-implemented it with "new and
- improved" algorithm. It keeps track of "wasted" file-fragment in
- the free-list too.
- * Removed limitation that the data transfer buffer size needed to be
- set for datasets whose dimensions were too large for the 'all' selection
- code to handle. Any size dimensioned datasets should be handled
- correctly now.
- * Changed behavior of H5Tget_member_type to correctly emulate HDF5 v1.2.x
- when --enable-hdf5v1_2 configure flag is enabled.
- * 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.
- * Fixed a bug where reading or writing chunked data which needed datatype
- conversion could result in data values getting corrupted.
- * Fixed a bug where appending a point selection to the current selection
- would not actually append the point when there were no points defined
- currently.
- * Fixed a bug where 'or'ing a hyperslab with a 'none' selection would
- fail. Now adds that hyperslab as the first hyperlab in the selection.
- * Fixed a bug in the 'big' test where quota limits weren't being detected
- properly if they caused close() to fail.
- * Fixed a bug in internal B-tree code where a B-tree was not being copied
+ * Fixed bug where selection offset was being ignored for certain hyperslab
+ selections when optimized I/O was being performed. QAK - 2002/04/02
+ * Added serial multi-gigabyte file size test. "test/big -h" shows
+ the help page. AKC - 2002/03/29
+ * Fixed bug where variable-length string type doesn't behave as
+ string. SLU - 2002/03/28
+ * Fixed bug in H5Gget_objinfo() which was not setting the 'fileno'
+ of the H5G_stat_t struct. QAK - 2002/03/27
+ * Fixed data corruption bug in hyperslab routines when contiguous
+ hyperslab that spans entire dimension and is larger than type
+ conversion buffer is attempted to be read. QAK - 2002/03/26
+ * Fixed bug where non-zero fill-value was not being read correctly from
+ certain chunked datasets when using an "all" or contiguous hyperslab
+ selection. QAK - 2002/02/14
+ * Fixed bug where a preempted chunk in the chunk data could still be
+ used by an internal pointer and cause an assertion failure or core
+ dump. QAK - 2002/02/13
+ * Fixed bug where raw data re-allocated from the free-list would sometimes
+ overlap with the metadata accumulator and get corrupted. QAK - 2002/01/23
+ * Fixed bug where variable-length datatypes for attributes was not working
correctly.
+ * Retired the DPSS virtual file driver (--with-gridstorage configure
+ option).
+ * Corrected behavior of H5Tinsert to not allow compound datatype fields to
+ be inserted past the end of the datatype.
+ * Fixed the internal macros used to encode & decode file metadata, to avoid
+ an unaligned access warning on IA64 machines.
* Fixed an off-by-one error in H5Sselect_valid when hyperslab selections
which would allow hyperslab selections which overlapped the edge of the
selection by one element as valid.

Configuration
-------------
- * Changed the default value of $NPROCS from 2 to 3 since 3 processes
- have a much bigger chance catching parallel errors than just 2.
- * Basic port to Compaq (nee DEC) Alpha OSF 5.
- * Added --enable-linux-lfs flag to allow more control over whether to enable
- or disable large file support on Linux.
+ * Can use just enable-threadsafe if the C compiler has builtin pthreads
+ support.
* Require HDF (a.k.a. hdf4) software that consists of a newer version
of zlib library which consists of the compress2() function. Versions
HDF version 4.1r3 and newer meets this requirement. The compress2
uses a newer compression algorithm used by the HDF5 library. Also,
4.1r3 has an hdp tool that can handle "loops" in Vgroups.
- * Can use just enable-threadsafe if the C compiler has builtin pthreads
- support.
+ * Added --enable-linux-lfs flag to allow more control over whether to enable
+ or disable large file support on Linux.
+ * Basic port to Compaq (nee DEC) Alpha OSF 5.
+ * Changed the default value of $NPROCS from 2 to 3 since 3 processes
+ have a much bigger chance catching parallel errors than just 2.
Tools
-----
- * Fixed segfault when "-v" flag was used with the h5dumper.
+ * Fixed limitation in h5dumper with object names which reached over 1024
+ characters in length. We can now handle arbitrarily larger sizes for
+ object names. BW - 2002/02/27
* Fixed so that the "-i" flag works correctly with the h5dumper.
+ * Fixed segfault when "-v" flag was used with the h5dumper.

New Features
============
- * A helper script called ``h5cc'', which helps compilation of HDF5
- programs, is now distributed with HDF5. See the reference manual
- for information on how to use this feature.
+ * A new query function H5Tget_member_index has been added for compound
+ and enumeration data types, to retrieve member's index by name.
+ SLU - 2002/04/05
+ * Improved performance of "regular" hyperslab I/O when using MPI-IO and the
+ datatype conversion is unneccessary. QAK - 2002/04/02
+ * Improved performance of single hyperslab I/O when datatype conversion is
+ unneccessary. QAK - 2002/04/02
+ * Added new "H5Sget_select_type" API function to determine which type of
+ selection is defined for a dataspace ("all", "none", "hyperslab" or
+ "point"). QAK - 2002/02/7
+ * Added support to read/write portions of chunks directly, if they are
+ uncompressed and too large to cache. This should speed up I/O on chunked
+ datasets for a few more cases. QAK - 2002/01/31
+ * Parallel HDF5 is now supported on HP-UX 11.00 platforms.
+ * Added H5Rget_obj_type() API function, which performs the same functionality
+ as H5Rget_object_type(), but requires the reference type as a parameter
+ in order to correctly handle dataset region references. Moved
+ H5Rget_object_type() to be only compiled into the library when v1.4
+ compatibility is enabled.
+ * Changed internal error handling macros to reduce code size of library by
+ about 10-20%.
+ * Added a new file access property, file close degree, to control file
+ close behavior. It has four values, H5F_CLOSE_WEAK, H5F_CLOSE_SEMI,
+ H5F_CLOSE_STRONG, and H5F_CLOSE_DEFAULT. Two correspont functions
+ H5Pset_fclose_degree and H5Pget_fclose_degree are also provided. Two
+ new functions H5Fget_obj_count and H5Fget_obj_ids are offerted to assist
+ this new feature. For full details, please refer to the reference
+ manual under the description of H5Fcreate, H5Fopen, H5Fclose and the
+ functions mentioned above.
+ * Removed H5P(get|set)_hyper_cache API function, since the property is no
+ longer used.
+ * Improved performance of non-contiguous hyperslabs (built up with
+ several hyperslab selection calls).
+ * Improved performance of single, contiguous hyperslabs when reading or
+ writing.
+ * 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
+ are made.
+ * Added a new test to verify the information provided by the configure
+ command.
+ * 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 perform programs to test the HDF5 library performance. Programs
+ are installed in directory perform/.
+ * 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 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 a parallel HDF5 example examples/ph5example.c to illustrate
+ the basic way of using parallel HDF5.
+ * Added two simple parallel performance tests as mpi-perf.c (MPI
+ performance) and perf.c (PHDF5 performance) in testpar.
+ * Improved regular hyperslab I/O by about a factor of 6 or so.
+ * Modified the Pablo build procedure to permit building of the instrumented
+ library to link either with the Trace libraries as before or with the
+ Pablo Performance Caputure Facility.
+ * Verified correct operation of library on Solaris 2.8 in both 64-bit and
+ 32-bit compilation modes. See INSTALL document for instructions on
+ compiling the distribution with 64-bit support.
+ * Parallel HDF5 now runs on the HP V2500 and HP N4000 machines.
+ * H5 <-> GIF convertor has been added. This is available under
+ tools/gifconv. The convertor supports the ability to create animated
+ gifs as well.
+ * Added a global string variable H5_lib_vers_info_g which holds the
+ HDF5 library version information. This can be used to identify
+ an hdf5 library or hdf5 application binary.
+ Also added a verification of the consistency between H5_lib_vers_info_g
+ and other version information in the source code.
+ * File sizes greater than 2GB are now supported on Linux systems with
+ version 2.4.x or higher kernels.
+ * F90 APIs are available on HPUX 11.00 and IBM SP platforms.
+ * F90 static library is available on Windows platforms. See
+ INSTALL_Windows.txt for details.
+ * F90 API:
+ - Added aditional parameter "dims" to the h5dread/h5dwrite and
+ h5aread/h5awrite subroutines. This parameter is 1D array of size
+ 7 and contains the sizes of the data buffer dimensions.
