<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>

<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.

    <h3>New Functions</h3>
        The following functions are new for Release 1.4 and are included in the

        The following functions are new for Release 1.4, but

        <p>
        The following functions are new for Release 1.4 but are intended

    <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>

    <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.
