changelog</a>.</em></p>
<blockquote>
<h2>2.12.1 (2024-02-22)</h2>
<ul>
<li>Do not parse sourcemaps in <code>post-css</code>. This fixes a
vulnerability in which information about the existence or non-existence
of files on a server could be disclosed via properly crafted HTML input
when the <code>style</code> attribute is allowed by the configuration.
Thanks to the <a href="https://snyk.io/">Snyk Security team</a> for the
disclosure and to <a href="https://dylan.is/">Dylan Armstrong</a> for
the fix.</li>
</ul>
<h2>2.12.0 (2024-02-21)</h2>
<ul>
<li>
<p>Introduced the <code>allowedEmptyAttributes</code> option, enabling
explicit specification of empty string values for select attributes,
with the default attribute set to <code>alt</code>. Thanks to <a
href="https://github.com/zhna123">Na</a> for the contribution.</p>
</li>
<li>
<p>Clarified the use of SVGs with a new test and changes to
documentation. Thanks to <a href="https://github.com/gkumar9891">Gauav
Kumar</a> for the contribution.</p>
</li>
<li>
<p>Do not process source maps when processing style tags with
PostCSS.</p>
</li>
</ul>
