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. + * Parallel HDF5 now runs on the HP V2500 and HP N4000 machines. + * F90 API: + - Added aditional parameter "dims" to the h5dread_f/h5dwrite_f and + h5aread_f/h5awrite_f subroutines. This parameter is a 1-D array + of size 7 and contains the sizes of the data buffer dimensions. + This change enables portability between Windows and UNIX platforms. + In previous versions of the F90 APIs, the data buffer parameters of + the above functions were declared as assumed-shape arrays, which + were passed to the C functions by a descriptor. There is no + portable means, however, of passing descriptors from F90 to C, + causing portability problems between Windows and UNIX and among + UNIX platforms. With this change, the data buffers are assumed- + size arrays, which can be portably passed to the C functions. + * F90 static library is available on Windows platforms. + See INSTALL_Windows_withF90.txt for details. + * F90 APIs are available on HPUX 11.00 and 10.20 and IBM SP platforms. + * H5 <-> GIF convertor has been added. This is available under + tools/gifconv. The convertor supports the ability to create animated + gifs as well. + * 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. + * Added support for the Metrowerks Code Warrior compiler for Windows. + * For H4->H5 converter utility, added a new option to choose not to convert + HDF4 specified attributes(reference number, class) into HDF5 attributes. + * Added support chunking and compression in SDS and image in H4->H5 converter. + Currently HDF5 only supports gzip compression, so by default an HDF4 file + with any other compression method will be converted into an HDF5 file in + gzip compression. + * correct the order or reading HDF4 image array in H4->H5 conversion. + * 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. + * 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. + + +Bug Fixes since HDF5-1.4.1 Release +================================== + + * Fixed bug with non-zero userblock sizes causing raw data to not + write correctly. + * Fixed problems with Pablo build and linking with non-standard MPI I/O. + * 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. + * Added --enable-linux-lfs flag to allow more control over whether to + enable or disable large file support on Linux. + * Fixed various bugs releated to SDS dimensional scale conversions in H4->H5 + converter. + * Fixed a bug to correctly convert HDF4 objects with fill value into HDF5. + * 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. + + + +Documentation +============= + + * The H5T_conv_t and H5T_cdata_t structures are now properly defined + in the H5Tregister entry in the "H5T" section of the "HDF5 Reference + Manual" and described in detail in section 12, "Data Conversions," in + the "Datatypes" chapter of the "HDF5 User's Guide." + * The new tools h52gif and gif2h5 have been added to the "Tools" section + of the Reference Manual. + * A "Freespace Management" section has been added to the "Performance" + chapter of the User's Guide. + * Several user-reported bugs have been fixed since Release 1.4.1. + * The "HDF5 Image and Palette Specification" (in the "HDF5 Application + Developer's Guide") has been heavily revised.
