releases</a>.</em></p>
<blockquote>
<h2>0.103.6</h2>
<p>The extensible EKU validation released as part of 0.103.5 was
actually not usable due to missing type exports, and contained a
regression where empty ExtendedKeyUsage extensions would not trigger an
error. Both issues are fixed in this release.</p>
<h2>What's Changed</h2>
<ul>
<li>Export more types to enable ExtendedKeyUsageValidator
implementations by <a
href="https://github.com/djc"><code>@​djc</code></a> in <a
href="https://redirect.github.com/rustls/webpki/pull/381">rustls/webpki#381</a></li>
<li>Error on empty EKU extensions by <a
href="https://github.com/djc"><code>@​djc</code></a> in <a
href="https://redirect.github.com/rustls/webpki/pull/382">rustls/webpki#382</a></li>
