<h1>21.1.1 (2021-04-30)</h1>
<h2>Deprecations and Removals</h2>
<ul>
<li>Temporarily set the new &quot;Value for ... does not match&quot; location warnings level
to <em>DEBUG</em>, to hide them from casual users. This prepares pip 21.1 for CPython
inclusion, while pip maintainers digest the first intake of location mismatch
issues for the <code>distutils</code>-<code>sysconfig</code> transition. (<code>[#9912](pypa/pip#9912) &lt;https://github.com/pypa/pip/issues/9912&gt;</code>_)</li>
</ul>
<h2>Bug Fixes</h2>
<ul>
<li>This change fixes a bug on Python <!-- raw HTML omitted -->`_)</li>
<li>Fix compatibility between distutils and sysconfig when the project name is unknown outside of a virtual environment. (<code>[#9838](pypa/pip#9838) &lt;https://github.com/pypa/pip/issues/9838&gt;</code>_)</li>

built in an isolated environment. (<code>[#9878](pypa/pip#9878) &lt;https://github.com/pypa/pip/issues/9878&gt;</code>_)</li>
</ul>
<h1>21.1 (2021-04-24)</h1>
<h2>Process</h2>
<ul>
<li>Start installation scheme migration from <code>distutils</code> to <code>sysconfig</code>. A
warning is implemented to detect differences between the two implementations to
encourage user reports, so we can avoid breakages before they happen.</li>
</ul>
<h2>Features</h2>
<ul>
<li>Add the ability for the new resolver to process URL constraints. (<code>[#8253](pypa/pip#8253) &lt;https://github.com/pypa/pip/issues/8253&gt;</code>_)</li>
<li>Add a feature <code>--use-feature=in-tree-build</code> to build local projects in-place
when installing. This is expected to become the default behavior in pip 21.3;
see <code>Installing from local packages &lt;https://pip.pypa.io/en/stable/user_guide/#installing-from-local-packages&gt;</code>_
for more information. (<code>[#9091](pypa/pip#9091) &lt;https://github.com/pypa/pip/issues/9091&gt;</code>_)</li>
<li>Bring back the &quot;(from versions: ...)&quot; message, that was shown on resolution failures. (<code>[#9139](pypa/pip#9139) &lt;https://github.com/pypa/pip/issues/9139&gt;</code>_)</li>
<li>Add support for editable installs for project with only setup.cfg files. (<code>[#9547](pypa/pip#9547) &lt;https://github.com/pypa/pip/issues/9547&gt;</code>_)</li>
<li>Improve performance when picking the best file from indexes during <code>pip install</code>. (<code>[#9748](pypa/pip#9748) &lt;https://github.com/pypa/pip/issues/9748&gt;</code>_)</li>
<li>Warn instead of erroring out when doing a PEP 517 build in presence of
<code>--build-option</code>. Warn when doing a PEP 517 build in presence of
<code>--global-option</code>. (<code>[#9774](pypa/pip#9774) &lt;https://github.com/pypa/pip/issues/9774&gt;</code>_)</li>

<h2>Bug Fixes</h2>
