<blockquote>
<h1>3.2.3 (2025-12-14)</h1>
<h2>Features added</h2>
<ul>
<li>
<p>The C-API declarations were updated to include the new
<code>PyList_*()</code> functions.
(Github issue :issue:<code>7291</code>)</p>
</li>
<li>
<p>The <code>Py_mod_gil</code> module setting can now be changed with a
C macro, overriding
the <code>freethreading_compatible</code> directive setting.
(Github issue :issue:<code>7404</code>)</p>
</li>
</ul>
<h2>Bugs fixed</h2>
<ul>
<li>
<p>t-strings lost the last element when compiled for the Limited API.
(Github issue :issue:<code>7381</code>)</p>
</li>
<li>
<p>The <code>array.data</code> property of the
<code>cpython.array</code> declarations generated a
useless exception check that degraded its use in <code>nogil</code>
code.
(Github issue :issue:<code>7408</code>)</p>
</li>
<li>
<p>Parallel builds with the <code>cythonize</code> command could request
more processes
than allowed by the platform, thus failing the build.
(Github issue :issue:<code>7384</code>)</p>
</li>
<li>
<p>A minor thread sanitizer issue was resolved.
(Github issue :issue:<code>7383</code>)</p>
