releases</a>.</em></p>
<blockquote>
<h2>26.3.1</h2>
<h3>Stable style</h3>
<ul>
<li>Prevent Jupyter notebook magic masking collisions from corrupting
cells by using
exact-length placeholders for short magics and aborting if a placeholder
can no longer
be unmasked safely (<a
href="https://redirect.github.com/psf/black/issues/5038">#5038</a>)</li>
</ul>
<h3>Configuration</h3>
<ul>
<li>Always hash cache filename components derived from
<code>--python-cell-magics</code> so custom
magic names cannot affect cache paths (<a
href="https://redirect.github.com/psf/black/issues/5038">#5038</a>)</li>
</ul>
<h3><em>Blackd</em></h3>
<ul>
<li>Disable browser-originated requests by default, add configurable
origin allowlisting
and request body limits, and bound executor submissions to improve
backpressure
(<a
href="https://redirect.github.com/psf/black/issues/5039">#5039</a>)</li>
</ul>
<h2>26.3.0</h2>
<h3>Stable style</h3>
<ul>
<li>Don't double-decode input, causing non-UTF-8 files to be corrupted
(<a
href="https://redirect.github.com/psf/black/issues/4964">#4964</a>)</li>
<li>Fix crash on standalone comment in lambda default arguments (<a
href="https://redirect.github.com/psf/black/issues/4993">#4993</a>)</li>
<li>Preserve parentheses when <code># type: ignore</code> comments would
be merged with other
comments on the same line, preventing AST equivalence failures (<a
href="https://redirect.github.com/psf/black/issues/4888">#4888</a>)</li>
</ul>
<h3>Preview style</h3>
<ul>
<li>Fix bug where <code>if</code> guards in <code>case</code> blocks
were incorrectly split when the pattern had
a trailing comma (<a
href="https://redirect.github.com/psf/black/issues/4884">#4884</a>)</li>
<li>Fix <code>string_processing</code> crashing on unassigned long
string literals with trailing
commas (one-item tuples) (<a
href="https://redirect.github.com/psf/black/issues/4929">#4929</a>)</li>
<li>Simplify implementation of the power operator &quot;hugging&quot;
logic (<a
href="https://redirect.github.com/psf/black/issues/4918">#4918</a>)</li>
</ul>
<h3>Packaging</h3>
<ul>
<li>Fix shutdown errors in PyInstaller builds on macOS by disabling
multiprocessing in
frozen environments (<a
href="https://redirect.github.com/psf/black/issues/4930">#4930</a>)</li>
</ul>
<h3>Performance</h3>
<ul>
<li>Introduce winloop for windows as an alternative to uvloop (<a
href="https://redirect.github.com/psf/black/issues/4996">#4996</a>)</li>
<li>Remove deprecated function <code>uvloop.install()</code> in favor of
<code>uvloop.new_event_loop()</code>
(<a
href="https://redirect.github.com/psf/black/issues/4996">#4996</a>)</li>
<li>Rename <code>maybe_install_uvloop</code> function to
<code>maybe_use_uvloop</code> to simplify loop
installation and creation of either a uvloop/winloop evenloop or default
eventloop
(<a
href="https://redirect.github.com/psf/black/issues/4996">#4996</a>)</li>
