+New Features
+============
+
+Configuration:
+--------------
+The following flags have been added to the configuration script:
+--enable-hdf5v1_4 Compile the HDF5 v1.4 compatibility interface
+--enable-filters=all Turn on all internal I/O filters. One may also
+ specify a comma-separated list of filters or the
+ word no. The default is all internal I/O filters.
+--with-mpe=DIR Use MPE instrumentation [default=no]
+--with-szlib=DIR Use szlib library for external szlib I/O filter
+ [default=no]
+
+Library:
+--------
+ Summary: This release has the following new features that are not
+ available in 1.4.* releases
+
+ 1. Generic properties to give application more control on I/O pipeline
+ 2. Time allocation and fill value properties
+ 3. New filters: external compression filter szip
+ internal shuffling and checksum filters
+ 4. Compact storage layout for datasets
+ 5. Redesigned I/O pipeline for better performance.
+
+ For more information see
+ http://hdf.ncsa.uiuc.edu/HDF5/doc_resource/SZIP/index.html
+ http://hdf.ncsa.uiuc.edu/HDF5/doc/ADGuide.html
+ http://hdf.ncsa.uiuc.edu/HDF5/doc/ADGuide/Changes.html
+
+ Complete list of changes:
+
+ * Changed dataset modification time to _not_ be updated when raw data is
+ written to a dataset. The modification time is only updated when the
+ dataset's metadata is modified. QAK - 2003/06/10
+ * Changed H5Sget_select_bounds to use 'hssize_t *' for start and end
+ parameters, instead of 'hsize_t *', to better match other parts of the
+ dataspace API. QAK - 2003/06/04
+ * Changed raw data I/O to only access each chunk once, improving performance
+ in many situations with hyperslabs and large chunks or chunks with
+ filters. These improvements are currently limited to serial I/O, with
+ similar parallel I/O improvements forthcoming sometime in the future.
+ QAK - 2003/05/07
+ * Added parameter to the MPI/POSIX driver. If GPFS is enabled (by
+ modifying the H5FDmpiposix.c file to uncomment the USE_GPFS_HINTS
+ macro), then this extra parameter will turn GPFS hints on and off
+ during runtime. BW - 2003/05/05
+ * Added option to print 1-byte integer datasets as ASCII to h5dump. BW -
+ 2003/04/30
+ * Added a new utility "h5fc". It can be used to compile easily Fortran
+ programs which use HDF5. It automatically uses the compiler the HDF5
+ library was built with and links in any libraries HDF5 requires.
+ BW - 2003/04/10
+ * Added new dataset creation property list functions for working with
+ I/O filters: H5Pmodify_filter, H5Pget_filter_by_id and
+ H5Pall_filters_avail. Also changed H5Zregister to use new method
+ of registering filters with library. QAK - 2003/04/08
+ * The first version of szip compression support were implemented.
+ User should have static szlib library installed. Using function
+ H5Pset_szip to pass the szip parameters to the HDF5 library.
+ More detailed decription of the process will be followed.
+ KY-2003/04/01
+ * Added Fletcher32 checksum as a filter in pipeline. It only works in
+ chunked dataset. SLU - 2003/2/11
+ * MPICH/MPE instrumentation feature added. Use --with-mpe[=DIR] to configure
+ it. AKC - 2003/1/3
+ * New functions H5Gget_num_objs, H5Gget_objname_by_idx and H5Gget_objtype_by_idx
+ are added to the library. SLU - 2002/11/25
+ * H5Dget_offset is added to return the offset of a dataset's data relative
+ to the beginning of the file. SLU - 2002/11/7
+ * Functions H5Tget_native_type and H5Tis_variable_str are added. The first
+ one reconstructs a datatype based on native memory datatype. The second
+ one checks if a datatype is variable string. SLU - 2002/11/6
+ * Added environment variable "HDF5_DISABLE_VERSION_CHECK", which disables
+ the version checking between the header files and the library linked into
+ an application if set to '1'. This should be used with caution, mis-
+ matched headers and library binaries can cause _serious_ problems.
+ QAK - 2002/10/15
+ * Added new API function to get the name of an object in a file, using
+ an open ID (hid_t). QAK - 2002/10/14
+ * Added API functions to return pointer to low-level file handle
+ (H5Fget_vfd_handle and H5FDget_vfd_handle) and related property list
+ setting functions(H5Pset_family_offset and H5Pset_multi_type).
+ SLU - 2002/09/30
+ * Changed "H5P[set|get]_space_time" functions to "H5P[set|get]_alloc_time"
+ Unify all symbolic names for these functions to use "alloc time" instead
+ of other names. QAK - 2002/09/13
+ * Added "H5D_SPACE_ALLOC_INCR" setting to H5D_SPACE_ALLOC_EARLY and
+ H5D_SPACE_ALLOC_LATE for H5Dset_space_time(). This allows chunked
+ datasets to be incrementally allocated as in the 1.4.x branch.
+ QAK - 2002/08/27
+ * Compact dataset is added to the library. The data will be stored in
+ the header message of dataset layout. Space allocation time has to be
+ EARLY. No hyperslab is supported for parallel collective write. There
+ is no API changes except activating H5Pset_layout and H5Pget_layout for
+ compact dataset. -SLU, 2002/8/20
+ * 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
+ that are duplicated in the VFL 'close' callback function. QAK - 2002/05/20
+ * Added feature to parallel chunk allocation routine to not write fill
+ values to chunks allocated if the user has set the "fill time" to never.
+ This can improve parallel I/O performance for chunked
+ datasets. QAK - 2002/05/17
+ * New functions H5Glink2 and H5Gmove2 were added to allow link and move to
+ be in different locations in the same file. The old functions H5Glink
+ and H5Gmove remain valid. SLU - 2002/04/26
+ * Fill-value's behaviors for contiguous dataset have been redefined.
+ Basicly, dataset won't allocate space until it's necessary. Full details
+ are available at http://hdf.ncsa.uiuc.edu/RFC/Fill_Value, at this moment.
+ SLU - 2002/04/11
+ * Added new routine "H5Dfill" to fill a selection with a particular value
+ in memory. QAK - 2002/04/09
+ * 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 - 2002/02/07
+ * 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
+ * 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.
+ * 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.
+ * 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.
+ * Added new F90 APIs for generic properties, new filters, and
+ time/space allocation properties.
+ * C++ API:
+ - Added two new member functions: Exception::getFuncName() and
+ Exception::getCFuncName() to provide the name of the member
+ function, where an exception is thrown.
+ - IdComponent::operator= becomes a virtual function because
+ DataType, DataSpace, and PropList provide their own
+ implementation. The new operator= functions invoke H5Tcopy,
+ H5Scopy, and H5Pcopy to make a copy of a datatype, dataspace,
+ and property list, respectively.
+
+Parallel Library:
+-----------------
+
+Tools:
+------
+ * When the "-S" option for "simple" output is chosen, h5ls now displays
+ modification times of datasets in UTC instead of local time.
+ QAK - 2003/06/06
+ * h5diff to compare two HDF5 files was added
+ * h5import to import ascii and binary data to an HDF5 file was added.
+ Old h5import tool in the tools/misc directory was renamed to
+ h5createU8 to reflect its purpose. h5createU8 will be deleted in
+ 1.6.1 release.
+ * Two new scripts h5fc and h5c++ were added to compile F90 and C++
+ HDF5 applications.
+
+Support for new platforms, languages and compilers.
+=======================================
+ * Added C++ API support on HPUX11.00. BMR - 2003/03/19
+ * Absoft compiler is supported for Fortran HDF5 Library.
+ When building with Absoft compiler, add -DH5_ABSOFT to
+ C compilation flags to get correct names of C functions
+ called by Fortran APIs.
+
+
+Bug Fixes since HDF5-1.4.0 release
+==================================
+
+Library
+-------
+ * Don't attempt to perform collective I/O on chunked datasets with
+ parallel I/O. QAK - 2003/06/05
+ * The library now correctly reuses space when objects are deleted in the
+ file. This should be handled correctly for every situation, except
+ datasets with variable-length datatypes are not returning the space they
+ use in the global heap currently. QAK - 2003/04/13
+ * Fixed error in B-tree deletion routine which could cause groups to be
+ corrupted when objects are removed from them.
+ QAK - 2003/04/11
+ * Fixed error in file space freeing code which could cause metadata to
+ fail to be written to the file.
+ QAK - 2003/04/11
+ * -O caused errors in AIX 5.x platforms. Removed it from
+ --enable-production mode. AKC - 2003/03/31
+ * Corrected memory/resource leaks in per-thread key information when
+ thread-safe operation was enabled. QAK - 2003/02/07
+ * Improved error assertion for nil VL strings, making it fails with error
+ stack instead of just assertion failure. SLU - 2002/12/16
+ * Added two new API functions: H5Zunregister & H5Zfilter_avail.
+ QAK - 2002/11/16
+ * Add data shuffle filter(source code H5Zshuffle.c), the combination of the
+ shuffling and compression can make data compression better without suffering
+ much encoding and decoding CPU time for many application datasets(especially
+ for floating point data). This adds a new API function: H5Pset_shuffle.
+ KY - 2002/11/13
+ * Allow scalar dataspaces to be used for parallel I/O. QAK - 2002/11/05
+ * New functions H5Gget_comment(modification), H5Aget_storage_size,
+ H5Arename. SLU - 2002/10/29
+ * Fixed an assertion of H5S_select_iterate that did not account for scalar
+ type that has no dimension sizes. AKC - 2002/10/15
+ * Partially fixed space allocation inefficiencies in the file by
+ improving our algorithms for re-using freed space. QAK - 2002/08/27
+ * Fixed data corruption problem which could occur when fill values were
+ written to a contiguously stored dataset in parallel. QAK - 2002/08/27
+ * Fixed VL memory leak when data is overwritten. The heap objects holding
+ old data are freed. If the fill value writting time is set to
+ H5D_FILL_TIME_NEVER, the library prohibits user to create VL type dataset.
+ The library free all the heap objects storing VL type if there is nested
+ VL type(a VL type contains another VL type). SLU - 2002/07/10
+ * Tweaked a few API functions to use 'size_t' instead of 'unsigned' or
+ 'hsize_t', which may cause errors in some cases.
+
+
+Configuration
+-------------
+ * Included the both the examples of fortran and c++ "make check-install"
+ testing. This tests the correctness of the h5fc command. AKC - 2003/04/22
+ * When using gcc 3.x, we use -std=c99 instead of -ansi for compiling.
+ QAK - 2003/04/11
+ * IA64 platform has its own configure setting and use Intel Compilers as
+ the default compilers (were gcc and pgf90 before.) This also eliminated
+ the segmentation fault in the fortran test. The missing reference of
+ "exit" is fixed too. AKC - 2003/04/02
+
+Performance
+-------------
+ * Improved dataset creation time by about 30% (relative to the 1.4.x
+ branch).
+
+Tools
+-----
+
+ * Added a -force option to h5redeploy. AKC - 2003/03/04
+ * The VL string bug(data and datatype cannot be shown) in h5dump is fixed.
+ -SLU - 2002/11/18
+ * Fixed segfault if h5dump was invoked with some options but no file
+ (e.g., h5dump -H). -AKC, 2002/10/15
+ * Fixed so that the "-i" flag works correctly with the h5dumper.
+ * Fixed segfault when "-v" flag was used with the h5dumper.

+Known Problems
+==============
+
+* PGI C++ compiler fails when compiling the C++ library's tests.
+ Therefore, we cannot verify that the C++ library built with the PGI C++
+ compiler is correct.
+
+* The h5dump tests may fail to match the expected output on some platforms
+ (e.g. parallel jobs, Windows) where the error messages directed to
+ "stderr" do not appear in the "right order" with output from stdout.
+ This is not an error.
+
+* The stream-vfd test uses ip port 10007 for testing. If another
+ application is already using that port address, the test will hang
+ indefinitely and has to be terminated by the kill command. To try the
+ test again, change the port address in test/stream_test.c to one not
+ being used in the host.
+
+* The --enable-static-exec configure flag fails to compile for Solaris
+ platforms. This is due to the fact that not all of the system
+ libraries on Solaris are available in a static format.
+
+ The --enable-static-exec configure flag also fails to correctly compile
+ on IBM SP2 platform for the serial mode. The parallel mode works fine
+ with this option.
+
+ It is suggested that you don't use this option on these platforms
+ during configuration.
+
+* With the gcc 2.95.2 compiler, HDF 5 uses the `-ansi' flag during
+ compilation. The ANSI version of the compiler complains about not being
+ able to handle the `long long' datatype with the warning:
+
+ warning: ANSI C does not support `long long'
+
+ This warning is innocuous and can be safely ignored.
+
+
+* The Stream VFD was not tested yet under Windows. It is not supported
+ in the TFLOPS machine.
+
+
+* The ./dsets tests failed in the TFLOPS machine if the test program,
+ dsets.c, is compiled with the -O option. The hdf5 library still works
+ correctly with the -O option. The test program works fine if it is
+ compiled with -O1 or -O0. Only -O (same as -O2) causes the test
+ program to fail.
+
+* Certain platforms give false negatives when testing h5ls:
+ - Cray J90 and Cray T90IEEE give errors during testing when displaying
+ some floating-point values. These are benign differences due to
+ the different precision in the values displayed and h5ls appears to
+ be dumping floating-point numbers correctly.
+
+* Before building HDF5 F90 Library from source on Crays
+ replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src
+ subdirectory in the top level directory with the Cray-specific files
+ from the site:
+
+* On some platforms that use Intel compilers to build HDF5 fortran library,
+ compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90
+ complaining about exit subroutine. Comment out the line
+ IF (total_error .ne. 0) CALL exit (total_error)
+
+ ftp://hdf.ncsa.uiuc.edu/pub/outgoing/hdf5/hdf5-1.6.0/F90_source_for_Crays
+
+* On IA32 and IA64 systems, if you use a compiler other than GCC (such as
+ Intel's ecc or icc compilers), you will need to modify the generated
+ "libtool" program after configuration is finished. On or around line 104 of
+ the libtool file, there are lines which look like:
+
+ # How to pass a linker flag through the compiler.
+ wl=""
+
+ change these lines to this:
+
+ # How to pass a linker flag through the compiler.
+ wl="-Wl,"
+
+ UPDATE: This is now done automatically by the configure script. However, if
+ you still experience a problem, you may want to check this line in the
+ libtool file and make sure that it has the correct value.
+
+* Information about building with PGI and Intel compilers is available in
+ INSTALL file sections 5.7 and 5.8
