Bumps [cython](https://github.com/cython/cython) from 3.2.3 to 3.2.4. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/cython/cython/blob/master/CHANGES.rst";>cython's changelog</a>.</em></p> <blockquote> <h1>3.2.4 (2026-01-04)</h1> <h2>Features added</h2> <ul> <li> <p>In preparation of Cython 3.3, a new decorator <code>@collection_type(tname)</code> can be used to advertise an extension type as being a <code>'sequence'</code> or <code>'mapping'</code>. This currently only has the effect of setting the <code>Py_TPFLAGS_SEQUENCE</code> flag on the type or not, but is provided for convenience to allow using the new decorator already in Cython 3.2 code.</p> </li> <li> <p>Several C++ exception declarations were added to <code>libcpp.exceptions</code>. (Github issue :issue:<code>7389</code>)</p> </li> </ul> <h2>Bugs fixed</h2> <ul> <li> <p>Pseudo-literal default values of function arguments like <code>arg=str()</code> could generate invalid C code when internally converted into a real literal. (Github issue :issue:<code>6192</code>)</p> </li> <li> <p>The pickle serialisation of extension types using the <code>auto_pickle</code> feature was larger than necessary since 3.2.0 for types without Python object attributes. It is now back to the state before 3.2.0 again. (Github issue :issue:<code>7443</code>)</p> </li> <li> <p>Constants are now only made immortal on freethreading Python if they are not shared. (Github issue :issue:<code>7439</code>)</p> </li> <li> <p><code>PyDict_SetDefaultRef()</code> is now used when available to avoid temporary borrowed references. (Github issue :issue:<code>7347</code>)</p> </li> <li> <p>Includes all fixes as of Cython 3.1.8.</p> </li> </ul> </blockquote> </details> <details> <summary>Commits</summary> <ul> <li><a href="https://github.com/cython/cython/commit/21bda420d583bcf464fb9efb932b09c5f3db1efd";><code>21bda42</code></a> Update changelog.</li> <li><a href="https://github.com/cython/cython/commit/ea5e926e930fb50bd0b2be69717cb906f67ef18b";><code>ea5e926</code></a> Define missing C++ exception classes (<a href="https://redirect.github.com/cython/cython/issues/7389";>#7389</a>)</li> <li><a href="https://github.com/cython/cython/commit/c533d67f2a9109111c4057b598d8d04698cfee3f";><code>c533d67</code></a> Add sequence return type annotations in Parsing.py (<a href="https://redirect.github.com/cython/cython/issues/7416";>GH-7416</a>)</li> <li><a href="https://github.com/cython/cython/commit/d056a1808298ff6a569f950937b7ab3385b2f785";><code>d056a18</code></a> Allow 'mapping' as <a href="https://github.com/collection";><code>@​collection</code></a>_type() in preparation of 3.3, but without actu...</li> <li><a href="https://github.com/cython/cython/commit/d347c82898f4e90139b63510d984860762c01f1c";><code>d347c82</code></a> Remove exclusion of collection_type in test (<a href="https://redirect.github.com/cython/cython/issues/7442";>#7442</a>)</li> <li><a href="https://github.com/cython/cython/commit/fd6e8253df013645fb028ea956175957dcff8e8b";><code>fd6e825</code></a> Merge branch '3.1.x' into 3.2.x</li> <li><a href="https://github.com/cython/cython/commit/ce5c6cb05bdb5560937648558508241c681369ca";><code>ce5c6cb</code></a> Update changelog.</li> <li><a href="https://github.com/cython/cython/commit/74b97f92075d2721abce7dfb246f426b0ab401ae";><code>74b97f9</code></a> Fix arg=str() default argument (<a href="https://redirect.github.com/cython/cython/issues/6193";>GH-6193</a>)</li> <li><a href="https://github.com/cython/cython/commit/9c9e5c7d31525672ad5b8ee703c719a33d98a118";><code>9c9e5c7</code></a> Avoid immortalizing anything shared on freethreading (<a href="https://redirect.github.com/cython/cython/issues/7439";>GH-7439</a>)</li> <li><a href="https://github.com/cython/cython/commit/9d5507bf1cf713c314a9e37447463ad72ee9f8cd";><code>9d5507b</code></a> Fix accidental inefficiency in auto-pickling that always stored the object st...</li> <li>Additional commits viewable in <a href="https://github.com/cython/cython/compare/3.2.3...3.2.4";>compare view</a></li> </ul> </details> <br /> [](https://docs.github.com/en/github/managing-security-vulnerabilities/about-dependabot-security-updates#about-compatibility-scores) Dependabot will resolve any conflicts with this PR as long as you don't alter it yourself.
