HDF5 Release 1.4.1
INTRODUCTION
This document describes the differences between HDF5-1.4.0 and
HDF5-1.4.1, and contains information on the platforms tested and
known problems in HDF5-1.4.1. For more details check the HISTORY.txt
file in the HDF5 source.
The HDF5 documentation can be found on the NCSA ftp server
(ftp.ncsa.uiuc.edu) in the directory:
/HDF/HDF5/docs/
For more information look at the HDF5 home page at:
http://hdf.ncsa.uiuc.edu/HDF5/
If you have any questions or comments, please send them to:
hdfhelp@ncsa.uiuc.edu
CONTENTS
- New Features
- Bug Fixes since HDF5-1.4.0
- Documentation
- Platforms Tested
- Supported Configuration Features
- Known Problems
New Features
============
* XML output option for h5dump utility.
A new option --xml to output data in XML format has been added. The
XML output contains a complete description of the file, marked up in
XML.
The XML conforms to the HDF5 Document Type Definition (DTD), which
is available at:
http://hdf.ncsa.uiuc.edu/DTDs/HDF5-File.dtd
The XML output is suitable for use with other tools, including the
Java Tools:
http://hdf.ncsa.uiuc.edu/java-hdf5-html
Bug Fixes since HDF5-1.4.0 Release
==================================
* h4toh5 utility: conversion of images is fixed
Earlier releases of the h4toh5 utility produced images that did not
correctly conform to the HDF5 Image and Palette Specification.
http://hdf.ncsa.uiuc.edu/HDF5/doc/ImageSpec.html
Several required HDF5 attributes are omitted, and the dataspace
is reversed (i.e., the ht. and width of the image dataset is
incorrectly described.) For more information, please see:
http://hdf.ncsa.uiuc.edu/HDF5/H5Image/ImageDetails.htm
* 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.
Documentation
=============
PDF and Postscript versions of the following documents are available
for this release:

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.
