<blockquote>
<h1>22.1.1 (2022-05-20)</h1>
<h2>Bug Fixes</h2>
<ul>
<li>Properly filter out optional dependencies (i.e. extras) when checking build environment distributions. (<code>[#11112](pypa/pip#11112) &lt;https://github.com/pypa/pip/issues/11112&gt;</code>_)</li>
<li>Change the build environment dependency checking to be opt-in. (<code>[#11116](pypa/pip#11116) &lt;https://github.com/pypa/pip/issues/11116&gt;</code>_)</li>
<li>Allow using a pre-release version to satisfy a build requirement. This helps
manually populated build environments to more accurately detect build-time
requirement conflicts. (<code>[#11123](pypa/pip#11123) &lt;https://github.com/pypa/pip/issues/11123&gt;</code>_)</li>
