<blockquote>
<h1>23.2 (2023-07-15)</h1>
<h2>Process</h2>
<ul>
<li>Deprecate support for eggs for Python 3.11 or later, when the new
<code>importlib.metadata</code> backend is used to load distribution
metadata. This only affects the egg <em>distribution format</em> (with
the <code>.egg</code> extension); distributions using the
<code>.egg-info</code> <em>metadata format</em> (but are not actually
eggs) are not affected. For more information about eggs, see
<code>relevant section in the setuptools documentation
&lt;https://setuptools.pypa.io/en/stable/deprecated/python_eggs.html&gt;</code>__.</li>
</ul>
<h2>Deprecations and Removals</h2>
<ul>
<li>Deprecate legacy version and version specifiers that don't conform
to <code>PEP 440 &lt;https://peps.python.org/pep-0440/&gt;</code>_
(<code>[#12063](pypa/pip#12063)
&lt;https://github.com/pypa/pip/issues/12063&gt;</code>_)</li>
<li><code>freeze</code> no longer excludes the <code>setuptools</code>,
<code>distribute</code>, and <code>wheel</code>
from the output when running on Python 3.12 or later, where they are not
included in a virtual environment by default. Use <code>--exclude</code>
if you wish to
exclude any of these packages.
(<code>[#4256](pypa/pip#4256)
&lt;https://github.com/pypa/pip/issues/4256&gt;</code>_)</li>
</ul>

user can make the difference.
(<code>[#12040](pypa/pip#12040)
&lt;https://github.com/pypa/pip/issues/12040&gt;</code>_)</li>
</ul>

&lt;https://github.com/pypa/pip/issues/11417&gt;</code>_)</li>
<li>Prevent downloading files twice when PEP 658 metadata is present
(<code>[#11847](pypa/pip#11847)
&lt;https://github.com/pypa/pip/issues/11847&gt;</code>_)</li>
<li>Add permission check before configuration
(<code>[#11920](pypa/pip#11920)
&lt;https://github.com/pypa/pip/issues/11920&gt;</code>_)</li>

cache of locally built wheels.
(<code>[#11985](pypa/pip#11985)
&lt;https://github.com/pypa/pip/issues/11985&gt;</code>_)</li>
<li>Fix installation of packages with PEP658 metadata using
non-canonicalized names
(<code>[#12038](pypa/pip#12038)
&lt;https://github.com/pypa/pip/issues/12038&gt;</code>_)</li>
<li>Correctly parse <code>dist-info-metadata</code> values from

overlap between already installed and to-be-installed packages.
(<code>[#12079](pypa/pip#12079)
&lt;https://github.com/pypa/pip/issues/12079&gt;</code>_)</li>
<li>Pass the <code>-r</code> flag to mercurial to be explicit that a
revision is passed and protect
against <code>hg</code> options injection as part of VCS URLs. Users
that do not have control on
VCS URLs passed to pip are advised to upgrade.
