<blockquote>
<h1>v75.6.0</h1>
<h2>Features</h2>
<ul>
<li>Preserve original <code>PKG-INFO</code> into <code>METADATA</code>
when creating wheel
(instead of calling <code>wheel.metadata.pkginfo_to_metadata</code>).
This helps to be more compliant with the flow specified in PEP 517. (<a
href="https://redirect.github.com/pypa/setuptools/issues/4701">#4701</a>)</li>
<li>Changed the <code>WindowsSdkVersion</code>,
<code>FrameworkVersion32</code> and <code>FrameworkVersion64</code>
properties of <code>setuptools.msvc.PlatformInfo</code> to return an
empty <code>tuple</code> instead of <code>None</code> as a fallthrough
case -- by :user:<code>Avasam</code> (<a
href="https://redirect.github.com/pypa/setuptools/issues/4754">#4754</a>)</li>
</ul>
<h1>v75.5.0</h1>
<h2>Features</h2>
<ul>
<li>Removed support for
<code>SETUPTOOLS_DANGEROUSLY_SKIP_PYPROJECT_VALIDATION</code>, as it
is deemed prone to errors. (<a
href="https://redirect.github.com/pypa/setuptools/issues/4746">#4746</a>)</li>
</ul>
<h1>v75.4.0</h1>
<h2>Features</h2>
<ul>
<li>
<p>Added support for the environment variable
<code>SETUPTOOLS_DANGEROUSLY_SKIP_PYPROJECT_VALIDATION=true</code>,
allowing users to bypass
the validation of <code>pyproject.toml</code>.
This option should be used only as a last resort when resolving
dependency
issues, as it may lead to improper functioning.
Users who enable this setting are responsible for ensuring that
<code>pyproject.toml</code>
complies with setuptools requirements. (<a
href="https://redirect.github.com/pypa/setuptools/issues/4611">#4611</a>)</p>
<p>.. attention::
This environment variable was removed in a later version of
<code>setuptools</code>.</p>
</li>
<li>
<p>Require Python 3.9 or later. (<a
href="https://redirect.github.com/pypa/setuptools/issues/4718">#4718</a>)</p>
</li>
<li>
<p>Remove dependency on <code>importlib_resources</code>
and the vendored copy of the library.
Instead, <code>setuptools</code> consistently rely on stdlib's
<code>importlib.resources</code>
(available on Python 3.9+). (<a
href="https://redirect.github.com/pypa/setuptools/issues/4718">#4718</a>)</p>
</li>
<li>
<p>Setuptools' <code>bdist_wheel</code> implementation no longer
produces wheels with
the <code>m</code> SOABI flag (pymalloc-related).
This flag was removed on Python 3.8+ (see
:obj:<code>sys.abiflags</code>). (<a
href="https://redirect.github.com/pypa/setuptools/issues/4718">#4718</a>)</p>
</li>
<li>
<p>Updated vendored packaging version to 24.2. (<a
href="https://redirect.github.com/pypa/setuptools/issues/4740">#4740</a>)</p>
</li>
