<blockquote>
<h1>22.0.4 (2022-03-06)</h1>
<h2>Deprecations and Removals</h2>
<ul>
<li>Drop the doctype check, that presented a warning for index pages that use non-compliant HTML 5. (<code>[#10903](pypa/pip#10903) &lt;https://github.com/pypa/pip/issues/10903&gt;</code>_)</li>
</ul>
<h2>Vendored Libraries</h2>
<ul>
<li>Downgrade distlib to 0.3.3.</li>
</ul>
<h1>22.0.3 (2022-02-03)</h1>
<h2>Features</h2>
<ul>
<li>Print the exception via <code>rich.traceback</code>, when running with <code>--debug</code>. (<code>[#10791](pypa/pip#10791) &lt;https://github.com/pypa/pip/issues/10791&gt;</code>_)</li>
</ul>
<h2>Bug Fixes</h2>
<ul>
<li>
<p>Only calculate topological installation order, for packages that are going to be installed/upgraded.</p>
<p>This fixes an <code>AssertionError</code> that occured when determining installation order, for a very specific combination of upgrading-already-installed-package + change of dependencies + fetching some packages from a package index. This combination was especially common in Read the Docs' builds. (<code>[#10851](pypa/pip#10851) &lt;https://github.com/pypa/pip/issues/10851&gt;</code>_)</p>
</li>
<li>
<p>Use <code>html.parser</code> by default, instead of falling back to <code>html5lib</code> when <code>--use-deprecated=html5lib</code> is not passed. (<code>[#10869](pypa/pip#10869) &lt;https://github.com/pypa/pip/issues/10869&gt;</code>_)</p>
</li>
</ul>
<h2>Improved Documentation</h2>
<ul>
<li>Clarify that using per-requirement overrides disables the usage of wheels. (<code>[#9674](pypa/pip#9674) &lt;https://github.com/pypa/pip/issues/9674&gt;</code>_)</li>
</ul>
