<div></div>
</div>
<div class="abstract"><p>Here is a summary of the major changes in <span class="application">Universal Feed Parser</span> 4.0.</p></div>
<div class="itemizedlist"><ul>
<li>Support for <a href="annotated-atom10.html" title="Atom 1.0">Atom 1.0</a>.</li>
<li>Support for <span class="application">iTunes</span> extensions.</li>
<li>Support for <tt class="literal">dc:contributor</tt>.</li>
<li>
<span class="application">Universal Feed Parser</span> now captures the feed's <a href="reference-namespaces.html" title="namespaces">namespaces</a>. See <a href="namespace-handling.html" title="Namespace Handling">Namespace Handling</a> for details.</li>
<li>Lots of things have been renamed to match Atom 1.0 terminology. <tt class="literal">issued</tt> is now <a href="reference-entry-published.html" title="entries[i].published">entries[i].published</a>, <tt class="literal">modified</tt> is now <a href="reference-entry-updated.html" title="entries[i].updated">entries[i].updated</a>, and <tt class="literal">url</tt> is now <tt class="literal">href</tt> everywhere. You can still access these elements with the old names, so you shouldn't need to change any existing code, but don't be surprised if you can't find them during debugging.</li>
<li>
<tt class="literal">category</tt> and <tt class="literal">categories</tt> have been replaced by <tt class="literal">tags</tt>, see <a href="reference-feed-tags.html" title="feed.tags">feed.tags</a> and <a href="reference-entry-tags.html" title="entries[i].tags">entries[i].tags</a>. The old names still work.</li>
<li>
<tt class="literal">mode</tt> is gone from all detail and content dictionaries. It was never terribly useful, since <span class="application">Universal Feed Parser</span> unescapes content automatically.</li>
<li>
<a href="reference-entry-source.html" title="entries[i].source">entries[i].source</a> is now a dictionary of feed metadata as per section 4.2.11 of RFC 4287. <span class="application">Universal Feed Parser</span> no longer supports the RSS 2.0's <tt class="literal">source</tt> element.</li>
<li>Content in unknown namespaces is no longer discarded (<a href="http://sourceforge.net/tracker/index.php?func=detail&aid=993305&group_id=112328&atid=661937">bug 993305</a>)</li>
<li>Lots of other bug fixes.</li>
