Updates the requirements on [mypy](https://github.com/python/mypy) to permit the latest version. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/python/mypy/blob/master/CHANGELOG.md";>mypy's changelog</a>.</em></p> <blockquote> <h1>Mypy Release Notes</h1> <h2>Next Release</h2> <h3>Packaging changes</h3> <ul> <li>No longer provide mypyc-accelerated wheels for macOS x86_64 [mypyc-wheels <a href="https://redirect.github.com/python/mypy/issues/119";>#119</a>](<a href="https://redirect.github.com/mypyc/mypy_mypyc-wheels/pull/119";>mypyc/mypy_mypyc-wheels#119</a>)</li> </ul> <h2>Mypy 2.3</h2> <p>We've just uploaded mypy 2.3.0 to the Python Package Index (<a href="https://pypi.org/project/mypy/";>PyPI</a>). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:</p> <pre><code>python3 -m pip install -U mypy </code></pre> <p>You can read the full documentation for this release on <a href="http://mypy.readthedocs.io";>Read the Docs</a>.</p> <h3>The Upcoming Switch to the New Native Parser</h3> <p>We are planning to enable the new native parser (<code>--native-parser</code>) by default soon. We recommend that you test the native parser in your projects and report any issues in the <a href="https://github.com/python/mypy/issues";>mypy issue tracker</a>.</p> <h3>Mypyc Free-threading Memory Safety</h3> <p>Free-threaded Python builds that don't have the GIL require additional synchronization primitives or lock-free algorithms to ensure memory safety when there are race conditions (for example, when a thread reads a list item while another thread writes the same list item concurrently). This release greatly improves memory safety of free threading.</p> <p>List operations are now memory-safe on free threaded Python builds, even in the presence of race conditions. This has some performance cost. For list-heavy workloads, using <code>librt.vecs.vec</code> instead of list is often significantly faster, but note that <code>vec</code> is not (and likely won't be) fully memory safe, and the user is expected to avoid race conditions. The newly introduced <code>librt.threading.Lock</code> helps with this. Using variable-length tuples can also be more efficient than lists, since tuples are immutable and don't require expensive synchronization to ensure memory safety.</p> <p>Instance attribute access is also (mostly) memory safe now on free-threaded builds in the presence of race conditions. We are planning to fix the remaining unsafe cases in a future release.</p> <p>Full list of changes:</p> <ul> <li>Make attribute access memory safe on free-threaded builds (Jukka Lehtosalo, PR <a href="https://redirect.github.com/python/mypy/pull/21705";>21705</a>)</li> <li>Fix unsafe borrowing of instance attributes with free-threading (Jukka Lehtosalo, PR <a href="https://redirect.github.com/python/mypy/pull/21688";>21688</a>)</li> <li>Make list get/set item more memory safe on free-threaded builds (Jukka Lehtosalo, PR <a href="https://redirect.github.com/python/mypy/pull/21683";>21683</a>)</li> <li>Don't borrow list items on free-threaded builds (Jukka Lehtosalo, PR <a href="https://redirect.github.com/python/mypy/pull/21679";>21679</a>)</li> <li>Make multiple assignment from list memory-safe on free-threaded builds (Jukka Lehtosalo, PR <a href="https://redirect.github.com/python/mypy/pull/21684";>21684</a>)</li> </ul> <!-- raw HTML omitted --> </blockquote> <p>...
