dependabot[bot] opened a new pull request, #41008: URL: https://github.com/apache/beam/pull/41008
Updates the requirements on [cython](https://github.com/cython/cython) to permit the latest version. <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>3.3.1 (2026-11-01)</h1> <p>Most of the bugs fixed in this release were regressions in 3.3.0.</p> <h2>Features added</h2> <ul> <li> <p>Declarations for the C99 <code>bool</code> type in <code><stdbool.h></code> were added. (Github issue :issue:<code>8011</code>)</p> </li> <li> <p>Fused function objects are slightly smaller in the Limited API. (Github issue :issue:<code>7967</code>)</p> </li> <li> <p>Cython warns when enabling subinterpreter support for modules that cannot currently support it for technical reasons. (Github issue :issue:<code>8006</code>)</p> </li> <li> <p>The shared module is now automatically declared as <code>freethreading_compatible</code> and sets <code>subinterpretes_compatible</code> as applicable (currently depending on memoryview usage). Both are overridable by users as usual. (Github issue :issue:<code>8037</code>)</p> </li> </ul> <h2>Bugs fixed</h2> <ul> <li> <p>Constant folding of multiplied sequences could return incorrect results. Patch by orztrickster. (Github issue :issue:<code>8021</code>)</p> </li> <li> <p>Cython 3.3.0 incorrectly assumed that Python integer powers always return integers. Patch by Clay Dugo. (Github issue :issue:<code>7989</code>)</p> </li> <li> <p>The return value of optimised calls to <code>dict.get()</code>, <code>dict.pop()</code> and <code>dict.setdefault()</code> were inferred independent of their default values, leading to incorrect C code being generated. (Github issue :issue:<code>7991</code>)</p> </li> <li> <p>Some redeclarations of annotated variables were incorrectly rejected. They are now generally allowed and Cython only warns about obviously incorrect cases. (Github issue :issue:<code>7920</code>)</p> </li> <li> <p>Type inference now respects <code>annotation_typing=False</code> for local variable annotations. Patch by GruffElixir. (Github issue :issue:<code>7994</code>)</p> </li> <li> <p>Type inference depended on arbitrary set ordering when circular references are involved. As an effect, the <code>Cython.Compiler.FlowControl</code> module was translated to slightly non-deterministic C code. (Github issue :issue:<code>8002</code>)</p> </li> <li> <p>Assigning different slices of the same memoryview to different extension type attributes could generate incorrect refcounting code.</p> </li> </ul> <!-- raw HTML omitted --> </blockquote> <p>...
