<blockquote>
<h2>23.7.0</h2>
<h3>Highlights</h3>
<ul>
<li>Runtime support for Python 3.7 has been removed. Formatting 3.7 code will still be

</ul>
<h3>Stable style</h3>
<ul>
<li>Fix a bug where an illegal trailing comma was added to return type annotations using
PEP 604 unions (<a href="https://redirect.github.com/psf/black/issues/3735">#3735</a>)</li>
<li>Fix several bugs and crashes where comments in stub files were removed or mishandled
under some circumstances (<a href="https://redirect.github.com/psf/black/issues/3745">#3745</a>)</li>
<li>Fix a crash with multi-line magic comments like <code>type: ignore</code> within parentheses
(<a href="https://redirect.github.com/psf/black/issues/3740">#3740</a>)</li>
<li>Fix error in AST validation when <em>Black</em> removes trailing whitespace in a type comment
(<a href="https://redirect.github.com/psf/black/issues/3773">#3773</a>)</li>
</ul>
<h3>Preview style</h3>
<ul>
<li>Implicitly concatenated strings used as function args are no longer wrapped inside
parentheses (<a href="https://redirect.github.com/psf/black/issues/3640">#3640</a>)</li>
<li>Remove blank lines between a class definition and its docstring (<a href="https://redirect.github.com/psf/black/issues/3692">#3692</a>)</li>
</ul>
<h3>Configuration</h3>
<ul>
<li>The <code>--workers</code> argument to <em>Black</em> can now be specified via the <code>BLACK_NUM_WORKERS</code>
environment variable (<a href="https://redirect.github.com/psf/black/issues/3743">#3743</a>)</li>
<li><code>.pytest_cache</code>, <code>.ruff_cache</code> and <code>.vscode</code> are now excluded by default (<a href="https://redirect.github.com/psf/black/issues/3691">#3691</a>)</li>
<li>Fix <em>Black</em> not honouring <code>pyproject.toml</code> settings when running <code>--stdin-filename</code>
and the <code>pyproject.toml</code> found isn't in the current working directory (<a href="https://redirect.github.com/psf/black/issues/3719">#3719</a>)</li>
<li><em>Black</em> will now error if <code>exclude</code> and <code>extend-exclude</code> have invalid data types in
<code>pyproject.toml</code>, instead of silently doing the wrong thing (<a href="https://redirect.github.com/psf/black/issues/3764">#3764</a>)</li>
</ul>
<h3>Packaging</h3>
<ul>
<li>Upgrade mypyc from 0.991 to 1.3 (<a href="https://redirect.github.com/psf/black/issues/3697">#3697</a>)</li>
<li>Remove patching of Click that mitigated errors on Python 3.6 with <code>LANG=C</code> (<a href="https://redirect.github.com/psf/black/issues/3768">#3768</a>)</li>
</ul>
<h3>Parser</h3>
<ul>
<li>Add support for the new PEP 695 syntax in Python 3.12 (<a href="https://redirect.github.com/psf/black/issues/3703">#3703</a>)</li>
</ul>
<h3>Performance</h3>
<ul>
<li>Speed up <em>Black</em> significantly when the cache is full (<a href="https://redirect.github.com/psf/black/issues/3751">#3751</a>)</li>
<li>Avoid importing <code>IPython</code> in a case where we wouldn't need it (<a href="https://redirect.github.com/psf/black/issues/3748">#3748</a>)</li>
</ul>
