-- Features Added since HDF5-1.2.1 
-- Bug Fixes since HDF5-1.2.1

-
-Features Added since HDF5-1.2.1
-===============================
-   * Added internal free-lists to reduce memory required by the library and
-     H5garbage_collect API function.
-   * h5dump displays opaque and bitfield types.
-   * New features added to snapshots.  Use 'snapshot help' to see a
-     complete list of features.
-   * Improved configure to detect if MPIO routines are available when
-     parallel mode is requested.
-
-Bug Fixes since HDF5-1.2.1
-==========================
-   * h5dump correctly displays compound datatypes, including simple and
-     nested compound types.
-   * h5dump correctly displays the committed copy of predefined types.
-   * Corrected an error in h5toh4 which did not convert the 32-bit
-     int from HDF5 to HDF4 correctly for the T3E platform.
-   * Corrected a floating point number conversion error for the
-     Cray J90 platform.  The error did not convert the value 0.0
-     correctly.
-   * Fixed error in H5Giterate which was not updating the "index" parameter
-     correctly.
-   * Fixed error in hyperslab iteration which was not walking through the
-     correct sequence of array elements if hyperslabs were staggered in a
-     certain pattern.
-   * Fixed several other problems in hyperslab iteration code.
-   * Fixed another H5Giterate bug which caused groups with large numbers
-     of objects in them to misbehave when the callback function returned
-     non-zero values.
-   * Changed return type of H5Aiterate and H5A_operator_t typedef to be
-     herr_t, to align them with the dataset and group iterator functions.
-   * Changed H5Screate_simple and H5Sset_extent_simple to not allow dimensions
-     of size 0 without the same dimension being unlimited.
-   * Improved metadata hashing & caching algorithms to avoid
-     many hash flushes and also removed some redundant I/O when moving metadata
-     blocks in the file.
-   * The libhdf5.settings file shows the correct machine byte-sex.
-   * The "struct(opt)" type conversion function which gets invoked for
-     certain compound datatype conversions was fixed for nested compound
-     types. This required a small change in the datatype conversion
-     function API.
-
-Known Problems
-==============
-
-o SunOS 5.6 with C WorkShop Compilers 4.2:  hyperslab selections will 
-  fail if library is compiled using optimization of any level.
-o TFLOPS: dsets test fails if compiled with optimization turned on.
-o J90: tools fail to dispay data for the datasets with a compound datatype.

-II. Release Information for hdf5-1.2.1
-
-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.
-
-Library
--------
-
-   * Error was fixed which was not allowing dataset region references to have
-     their regions retrieved correctly.
-   * Added internal free-lists to reduce memory required by the library and
-     H5garbage_collect API function
-   * Fixed error in H5Giterate which was not updating the "index" parameter
-     correctly.
-   * Fixed error in hyperslab iteration which was not walking through the
-     correct sequence of array elements if hyperslabs were staggered in a
-     certain pattern
-   * Fixed several other problems in hyperslab iteration code.
-
-Tests
-------
-
-   * Added additional tests for group and attribute iteration.
-   * Added additional test for staggered hyperslab iteration.
-   * Added additional test for random 5-D hyperslab selection.
-
-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 doc/html/PSandPDF/index.html for more details.

-
-B. Known Problems
-   --------------
-
-* NT alpha 4.0
-  Dumper utiliy h5dump fails if linked with DLL.
-
-* SunOS 5.6 with C WorkShop Compilers 4.2
-  Hyperslab selections will fail if library is compiled using optimization
-  of any level.
-
- 
-C. Changes Since Version 1.0.1
-   ---------------------------
-
-1. Documentation
-   -------------
-
-* More examples
-
-* Updated user guide, reference manual, and format specification.
-
-* Self-contained documentation for installations isolated from the
-  Internet.
-
-* HDF5 Tutorial was added to the documentation  
-
-2. Configuration
-   -------------
-
-* Better detection and support for MPI-IO.
-
-* Recognition of compilers with known code generation problems.
-
-* Support for various compilers on a single architecture (e.g., the
-  native compiler and the GNU compilers).
-
-* Ability to build from read-only media and with different compilers
-  and/or options concurrently.
-
-* Added a libhdf5.settings file which summarizes the configuration
-  information and is installed along with the library.
-
-* Builds a shared library on most systems that support it.
-
-* Support for Cray T3E, J90 and Windows/NT.
-
-3. Debugging
-   ---------
-
-* Improved control and redirection of debugging and tracing messages.
-
-4. Datatypes
-   ---------
-
-* Optimizations to compound datatype conversions and I/O operations.
-
-* Added nearly 100 optimized conversion functions for native datatypes 
-  including support for non-aligned data.
-
-* Added support for bitfield, opaque, and enumeration types.
-
-* Added distinctions between signed and unsigned char types to the
-  list of predefined native hdf5 datatypes.
-
-* Added HDF5 type definitions for C9x types like int32_t.
-
-* Application-defined type conversion functions can handle non-packed
-  data.
-
-* Changed the H5Tunregister() function to use wildcards when matching
-  conversion functions.  H5Tregister_hard() and H5Tregister_soft()
-  were combined into H5Tregister().
-
-* Support for variable-length datatypes (arrays of varying length per
-  dataset element). Variable length strings currently supported only
-  as variable length arrays of 1-byte integers.
-
-5. Dataspaces
-   ----------
-
-* New query functions for selections.
-
-* I/O operations bypass the stripmining loop and go directly to
-  storage for certain contiguous selections in the absense of type
-  conversions.  In other cases the stripmining buffers are used more
-  effectively.
-
-* Reduced the number of I/O requests under certain circumstances,
-  improving performance on systems with high I/O latency.
-
-6. Persistent Pointers
-   -------------------
-
-* Object (serial and parallel) and dataset region (serial only)
-  references are implemented.
-
-7. Parallel Support
-   ----------------
-
-* Improved parallel I/O performance.
-
-* Supported new platforms: Cray T3E, Linux, DEC Cluster.
-
-* Use vendor supported version of MPIO on SGI O2K and Cray platforms.
-
-* Improved the algorithm that translates an HDF5 hyperslab selection
-  into an MPI type for better collective I/O performance.

-IV. Changes from Release 1.0.0 to Release 1.0.1
-
-* [Improvement]: configure sets up the Makefile in the parallel tests
-  suit (testpar/) correctly.
-
-* [Bug-Fix]: Configure failed for all IRIX versions other than 6.3.
-  It now configures correctly for all IRIX 6.x version.
-
-* Released Parallel HDF5 
-
-     Supported Features:
-     ------------------
-
-     HDF5 files are accessed according to the communicator and INFO
-     object defined in the property list set by H5Pset_mpi.
-
-     Independent read and write accesses to fixed and extendable dimension
-     datasets.
-
-     Collective read and write accesses to fixed dimension datasets.
-
-     Supported Platforms:
-     -------------------
-
-     Intel Red
-     IBM SP2
-     SGI Origin 2000
-
-     Changes In This Release: 
-     -----------------------
-
-   o Support of Access to Extendable Dimension Datasets.
-     Extendable dimension datasets must use chunked storage methods.
-     A new function, H5Dextend, is created to extend the current
-     dimensions of a dataset.  The current release requires the
-     MPI application must make a collective call to extend the
-     dimensions of an extendable dataset before writing to the
-     newly extended area.  (The serial does not require the
-     call of H5Dextend.  The dimensions of an extendable
-     dataset is increased when data is written to beyond the
-     current dimensions but within the maximum dimensions.)
-     The required collective call of H5Dextend may be relaxed
-     in future release.
-
-     This release only support independent read and write accesses
-     to extendable datasets.  Collective accesses to extendable
-     datasets will be implemented in future releases.
-
-   o Collective access to fixed dimension datasets.
-     Collective access to a dataset can be specified in the transfer
-     property list argument in H5Dread and H5Dwrite.  The current
-     release supports collective access to fixed dimension datasets.
-     Collective access to extendable datasets will be implemented in
-     future releases.
-
-   o HDF5 files are opened according to Communicator and INFO object.
-     H5Dopen now records the communicator and INFO setup by H5Pset_mmpi
-     and pass them to the corresponding MPIO open file calls for
-     processing.
-
-   o This release has been tested on IBM SP2, Intel Red and SGI Origin 2000
-     systems.  It uses the ROMIO version of MPIO interface for parallel
-     I/O supports.

-
-%%%%1.0.0%%%%   Release Information for hdf5-1.0.0
-
-V. Changes from the Beta 1.0.0 Release to Release 1.0.0
-
-* Added fill values for datasets.  For contiguous datasets fill value
-  performance may be quite poor since the fill value is written to the 
-  entire dataset when the dataset is created.  This will be remedied
-  in a future version.  Chunked datasets using fill values do not
-  incur any additional overhead. See H5Pset_fill_value().
-
-* Multiple hdf5 files can be "mounted" on one another to create a
-  larger virtual file. See H5Fmount().
-
-* Object names can be removed or changed but objects are never
-  actually removed from the file yet. See H5Gunlink() and H5Gmove().
-
-* Added a tuning mechanism for B-trees to insure that sequential
-  writes to chunked datasets use less overhead.  See H5Pset_btree_ratios().
-
-* Various optimizations and bug fixes.
-
-
-
-%%%%1.0.0 Beta%%%%   Release Information for hdf5-1.0.0 Beta
-
-VI. Changes from the Second Alpha 1.0.0 Release to the Beta 1.0.0 Release
-
-* Strided hyperslab selections in dataspaces now working.
-
-* The compression API has been replaced with a more general filter
-  API.  See doc/html/Filters.html for details.
-
-* Alpha-quality 2d ragged arrays are implemented as a layer built on
-  top of other hdf5 objects.  The API and storage format will almost
-  certainly change.
-
-* More debugging support including API tracing.  See Debugging.html.
-
-* C and Fortran style 8-bit fixed-length character string types are
-  supported with space or null padding or null termination and
-  translations between them.
-
-* Added function H5Fflush() to write all cached data immediately to
-  the file.
-
-* Datasets maintain a modification time which can be retrieved with
-  H5Gstat().
-
-* The h5ls tool can display much more information, including all the
-  values of a dataset.
-
-
-
-%%%%1.0.0 Alpha 2%%%%   Release Information for hdf5-1.0.0 Alpha 2
-
-VII. Changes from the First Alpha 1.0.0 Release to 
-     the Second Alpha 1.0.0 Release
-
-* Two of the packages have been renamed.  The data space API has been
-  renamed from `H5P' to `H5S' and the property list (template) API has 
-  been renamed from `H5C' to `H5P'.
-
-* The new attribute API `H5A' has been added.  An attribute is a small 
-  dataset which can be attached to some other object (for instance, a
-  4x4 transformation matrix attached to a 3-dimensional dataset, or an 
-  English abstract attached to a group).
-
-* The error handling API `H5E' has been completed.  By default, when an
-  API function returns failure an error stack is displayed on the
-  standard error stream.  The H5Eset_auto() controls the automatic
-  printing and H5E_BEGIN_TRY/H5E_END_TRY macros can temporarily
-  disable the automatic error printing.
-
-* Support for large files and datasets (>2GB) has been added.  There
-  is an html document that describes how it works.  Some of the types
-  for function arguments have changed to support this: all arguments
-  pertaining to sizes of memory objects are `size_t' and all arguments 
-  pertaining to file sizes are `hsize_t'.
-
-* More data type conversions have been added although none of them are
-  fine tuned for performance.  There are new converters from integer
-  to integer and float to float, but not between integers and floating
-  points.  A bug has been fixed in the converter between compound
-  types.
-
-* The numbered types have been removed from the API: int8, uint8,
-  int16, uint16, int32, uint32, int64, uint64, float32, and float64.
-  Use standard C types instead.  Similarly, the numbered types were
-  removed from the H5T_NATIVE_* architecture; use unnumbered types
-  which correspond to the standard C types like H5T_NATIVE_INT.
-
-* More debugging support was added.  If tracing is enabled at
-  configuration time (the default) and the HDF5_TRACE environment
-  variable is set to a file descriptor then all API calls will emit
-  the function name, argument names and values, and return value on
-  that file number.  There is an html document that describes this.
-  If appropriate debugging options are enabled at configuration time,
-  some packages will display performance information on stderr.
-
-* Data types can be stored in the file as independent objects and
-  multiple datasets can share a data type.
-
-* The raw data I/O stream has been implemented and the application can 
-  control meta and raw data caches, so I/O performance should be
-  improved from the first alpha release.
-
-* Group and attribute query functions have been implemented so it is
-  now possible to find out the contents of a file with no prior
-  knowledge.
-
-* External raw data storage allows datasets to be written by other
-  applications or I/O libraries and described and accessed through
-  HDF5.
-
-* Hard and soft (symbolic) links are implemented which allow groups to 
-  share objects. Dangling and recursive symbolic links are supported.
-
-* User-defined data compression is implemented although we may
-  generalize the interface to allow arbitrary user-defined filters
-  which can be used for compression, checksums, encryption,
-  performance monitoring, etc.  The publicly-available `deflate'
-  method is predefined if the GNU libz.a can be found at configuration 
-  time.
-
-* The configuration scripts have been modified to make it easier to
-  build debugging vs. production versions of the library.
-
-* The library automatically checks that the application was compiled
-  with the correct version of header files.
-
-
-		    Parallel HDF5 Changes
-
-* Parallel support for fixed dimension datasets with contiguous or
-  chunked storages.  Also, support unlimited dimension datasets which
-  must use chunk storage.  No parallel support for compressed datasets.
-
-* Collective data transfer for H5Dread/H5Dwrite.  Collective access
-  support for datasets with contiguous storage only, thus only fixed
-  dimension datasets for now.
-
-* H5Pset_mpi and H5Pget_mpi no longer have the access_mode
-  argument.  It is taken over by the data-transfer property list
-  of H5Dread/H5Dwrite.
-
-* New functions H5Pset_xfer and H5Pget_xfer to handle the
-  specification of independent or collective data transfer_mode
-  in the dataset transfer properties list.  The properties
-  list can be used to specify data transfer mode in the H5Dwrite
-  and H5Dread function calls.
-
-* Added parallel support for datasets with chunked storage layout.
-  When a dataset is extend in a PHDF5 file, all processes that open
-  the file must collectively call H5Dextend with identical new dimension
-  sizes.
-
