INTRODUCTION

|
|
This document describes the differences between HDF5-1.4.1 and
|
|
HDF5-1.4.2, and contains information on the platforms tested and
|
|
known problems in HDF5-1.4.2. For more details check the HISTORY.txt
|
|
file in the HDF5 source.

New Features
|
|
============
|
|
|
|
* File sizes greater than 2GB are now supported on Linux systems with
|
|
version 2.4.x or higher kernels.
|
|
* 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.
|
|
|
|
|
|
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.
|
|
* H5 <-> GIF convertor has been added. This is available under
|
|
tools/gifconv. The convertor supports the ability to create animated
|
|
gifs as well.

Supported Configuration Features Summary
|
|
========================================
|
|
|
|
* See "Supported Configuration Features Summary" section for the HDF5
|
|
1.4.0 release in the HISTORY.txt file.
|
|
|
|
|
|
Known Problems
|
|
==============
|
|
|
|
* The h5dump tests may fail to match the expected output in some
|
|
platforms (e.g. SP2 parallel, 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 --enable-static-exec configure flag fails to compile for HP-UX
|
|
11.00 platforms.
|
|
|
|
* The executable are always dynamic on IRIX64 6.5(64 and n32) and
|
|
IRIX 6.5 even if they are configured with --enable-static-exec.
|
|
|
|
* The shared library failed compilation on IRIX 6.5.
|
|
|
|
* After "make install" or "make install-doc" one may need to reload
|
|
the source from the tar file before doing another build.
|
|
|
|
* See "Known problems" section for the HDF5 1.4.0 release in the
|
|
HISTORY.txt file.
