<p><strong>WARNING:</strong> this is a security update.</p>
<p>When processing SVG files, CairoSVG could access other files online,
possibly
leading to very long renderings or other security problems.</p>
<p>This feature is now disabled by default. External resources can still
be
accessed using the &quot;unsafe&quot; or the &quot;url_fetcher&quot;
parameter.</p>
