<h1>HDF5 Software Changes from Release to Release</h1>
</center>
This document is intended to assist application developers who must keep
an application synchronized with the HDF5 library or related software.
<h2>Development Release 1.5 <br>(current development toward Production Release 1.6)</h2>
<dir>
This section lists the API-level changes that have been made during the
Release 1.5 development phase. (The development release number, 1.5,
will be used to describe this version until this the current development
cycle is completed, at which point it will be promoted to a production
release. The first production release of this code will be as Release 1.6.)
<p>
Note that changes at the subrelease level in the Release 1.4 production
branch, i.e., Releases 1.4.1, 1.4.2, ..., are summarized in the
Release 1.4.x versions of this document; they are not reported here.
<h3>New Functions</h3>
The following functions are new for Release 1.5 and are included in the
<a href="../RM_H5Front.html"><cite>HDF5 Reference Manual</cite></a>.
<dir>
<pre>
H5function with full syntax
</pre>
</dir>
<h3>Deleted Functions</h3>
The following functions have been removed from the HDF5 library
and from the <cite>HDF5 Reference Manual</cite>.
<dir>
<table>
<tr valign=top align=left><td>

</pre>
</td></tr>
</table>
</dir>
<h3>Functions with Changed Syntax</h3>
The following functions have changed slightly.
<dir>
<dl>
<dt><code>H5FDflush and VFL "flush" callbacks</code>
<dd>An extra parameter 'closing' has been added to these functions,
to allow the library to indicate that the file will be closed
following the call to "flush". Actions in the "flush" call
that are duplicated in the VFL "close" call may be omitted by
the VFL driver.
<dt><code>H5function</code>
<dd>Description of change
</dl>
</dir>
<h3>Constants with Changed Values</h3>
</dir>
<p>
<h2>Release 1.4</h2>
<dir>
Note: Changes at the subrelease level, i.e., 1.4.1, 1.4.2, ..., are
summarized in the Release 1.4.x version of this document; they are not
reported here.
Several functions were added to or removed from the HDF5 library
in the development of Release 1.4.
A few functions have been modified in minor ways.

ragged arrays, has been removed from the library.
<h3>Functions with Changed Syntax</h3>
The following functions have changed slightly.
<dir>
<dl>
<dt><code>H5Pget_buffer</code>
<dd>Return type has changed to <em>hsize_t</em>.
<dt><code>H5Pset_buffer</code>
<dd>The type of the <code>size</code> parameter has changed
to <em>hsize_t</em>.
<dt><code>H5Tconvert</code>
<dd>The type of the <code>nelmts</code> parameter has changed
to <em>hsize_t</em>.
</dl>
</dir>
<h3>Constants with Changed Values</h3>
The values of the constants <code>H5P_DEFAULT</code> and
<code>H5S_ALL</code> have been changed from <code>-2</code>
to <code>0</code>.
These default values had to be special-cased in situations where
they could be returned to distinguish them from error values.

<h2>This and Prior Releases: The RELEASE and HISTORY Files</h2>
<dir>
The HDF5 source code, as distributed to users and developers,
contains two files that will be of interest to readers of this
document. Both files are located at the top level of the
source code tree (i.e., in <code>.../hdf5/</code>) and are
duplicated here for your reference:
<p>
<dl>
<dt><a href="RELEASE.txt" target="ExtWin">RELEASE</a>
<dd>Technical notes regarding the release, including
new features and the changes since the last release,
notes regarding new or revised utilities,
notes regarding alternative language APIs (Fortran90, C++),
bugs fixed since the last release,
platforms on which the release has been tested,
and
known problems.
This is the file commonly known among developers as
"the release notes."
<p>
<dt><a href="HISTORY.txt" target="ExtWin">HISTORY</a>
<dd>A release-by-release history of the HDF5 library.
This file is a compiled set of the release notes
(i.e., the RELEASE files) from prior releases.
