<h1>3.2.0 (2025-11-05)</h1>
<p>(Complete changelog for the 3.2.0 release, including
pre-releases.)</p>
<h2>Features added</h2>
<ul>
<li>
<p>Builtin exception types are now inferred.
(Github issue :issue:<code>6908</code>)</p>
</li>
<li>
<p>The list of known, inferred and optimised Python builtins was
updated.
<code>range</code> is now considered a type. <code>ascii</code>,
<code>bin</code>, <code>format</code>, <code>hex</code>,
<code>oct</code> were added as functions.
(Github issue :issue:<code>6931</code>)</p>
</li>
<li>
<p>The f-string syntax was extended according to PEP-701.
(Github issue :issue:<code>5452</code>)</p>
</li>
<li>
<p>t-strings are implemented according to PEP-750. The implementation
backports the template classes
but prefers existing backports if installed separately.
(Github issue :issue:<code>6811</code>)</p>
</li>
<li>
<p>Unknown return type annotations with <code>-&gt;</code> are no longer
rejected but produce warnings.
This allows better integration with Python type hints that are not
always usable for Cython.
<code>-&gt; None</code>  is also allowed now.
Patch by jpe.  (Github issue :issue:<code>6946</code>)</p>
</li>
<li>
<p>The runtime Python dispatch for fused functions is substantially
faster.
(Github issues :issue:<code>1385</code>, :issue:<code>6996</code>)</p>
</li>
<li>
<p>Freelists (via cdef class decorator and for internally used types
such as <code>async</code>)
are now also used in the Limited API and with extension type specs
enabled.
(Github issue :issue:<code>7151</code>)</p>
</li>
<li>
<p>Module imports now quickly check for an already imported module to
speed up reimports.
Patch by Lysandros Nikolaou. (Github issue :issue:<code>7035</code>)</p>
</li>
<li>
<p>Type checks on PEP-604 union types (<code>int | None</code>) are
optimised into separate checks.
(Github issue :issue:<code>6935</code>)</p>
</li>
<li>
<p>Assignments to the PEP-604 union type <code>float | None</code> allow
any suitable Python number as input
and convert it to a Python <code>float</code> automatically.
(Github issue :issue:<code>5750</code>)</p>
</li>
<li>
<p>Item type inference was improved for looping over literals.
(Github issue :issue:<code>6912</code>)</p>
</li>
<li>
<p>Looping over literal sequences and strings now uses efficient C array
looping if possible.
(Github issue :issue:<code>6926</code>)</p>
</li>
</ul>
