<h1>Changes in version 4.2<a class="headerlink" href="#changes-in-version-4-2" title="Permalink to this headline">ΒΆ</a></h1>
<p><strong class="program">Universal Feed Parser</strong> 4.2 was released on 2008-03-12.</p>
<ul class="simple">
<li>Support for <a class="reference internal" href="microformats.html#advanced-microformats"><em>parsing microformats</em></a>, including <a class="reference internal" href="microformats.html#advanced-microformats-relenclosure"><em>rel=enclosure</em></a>, <a class="reference internal" href="microformats.html#advanced-microformats-reltag"><em>rel=tag</em></a>, <a class="reference internal" href="microformats.html#advanced-microformats-xfn"><em>XFN</em></a>, and <a class="reference internal" href="microformats.html#advanced-microformats-hcard"><em>hCard</em></a>.</li>
<li>Updated the whitelist of <a class="reference internal" href="html-sanitization.html#advanced-sanitization-html"><em>acceptable HTML elements and attributes</em></a> based on the latest draft of the <abbr title="HyperText Markup Language">HTML</abbr> 5 specification.</li>
<li>Support for <a class="reference internal" href="html-sanitization.html#advanced-sanitization-css"><em>CSS Sanitization</em></a>. (Previous versions of <strong class="program">Universal Feed Parser</strong> simply stripped all inline styles.) Many thanks to Sam Ruby for implementing this, despite my insistence that it was impossible.</li>
<li>Support for <a class="reference internal" href="html-sanitization.html#advanced-sanitization-svg"><em>SVG Sanitization</em></a>.</li>
<li>Support for <a class="reference internal" href="html-sanitization.html#advanced-sanitization-mathml"><em>MathML Sanitization</em></a>. Many thanks to Jacques Distler for patiently debugging this feature.</li>
<li><abbr title="International Resource Identifier">IRI</abbr> support for every element that can contain a <abbr title="Uniform Resource Identifier">URI</abbr>.</li>
<li>Ability to <a class="reference internal" href="resolving-relative-links.html#advanced-base-disable"><em>disable relative URI resolution</em></a>.</li>
<li>Command-line arguments and alternate serializers, for manipulating <strong class="program">Universal Feed Parser</strong> from shell scripts or other non-Python sources.</li>
<li>More robust parsing of author email addresses, misencoded win-1252 content, rel=self links, and better detection of HTML content in elements with ambiguous content types.</li>
