Bumps [mypy](https://github.com/python/mypy) from 1.18.2 to 1.19.0. <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>Drop Support for Python 3.9</h3> <p>Mypy no longer supports running with Python 3.9, which has reached end-of-life. When running mypy with Python 3.10+, it is still possible to type check code that needs to support Python 3.9 with the <code>--python-version 3.9</code> argument. Support for this will be dropped in the first half of 2026!</p> <p>Contributed by Marc Mueller (PR <a href="https://redirect.github.com/python/mypy/pull/20156";>20156</a>).</p> <h2>Mypy 1.19</h2> <p>We’ve just uploaded mypy 1.19.0 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>Python 3.9 Support Ending Soon</h3> <p>This is the last mypy feature release that supports Python 3.9, which reached end of life in October 2025.</p> <h3>Performance Improvements</h3> <ul> <li>Switch to a more dynamic SCC processing logic (Ivan Levkivskyi, PR <a href="https://redirect.github.com/python/mypy/pull/20053";>20053</a>)</li> <li>Speed up type aliases (Ivan Levkivskyi, PR <a href="https://redirect.github.com/python/mypy/pull/19810";>19810</a>)</li> </ul> <h3>Fixed‑Format Cache Improvements</h3> <p>Mypy uses a cache by default to speed up incremental runs by reusing partial results from earlier runs. Mypy 1.18 added a new binary fixed-format cache representation as an experimental feature. The feature is no longer experimental, and we are planning to enable it by default in a future mypy release (possibly 1.20), since it's faster and uses less space than the original, JSON-based cache format. Use <code>--fixed-format-cache</code> to enable the fixed-format cache.</p> <p>Mypy now has an extra dependency on the <code>librt</code> PyPI package, as it's needed for cache serialization and deserialization.</p> <p>Mypy ships with a tool to convert fixed-format cache files to the old JSON format. Example of how to use this:</p> <pre><code>$ python -m mypy.exportjson .mypy_cache/.../my_module.data.ff </code></pre> <!-- raw HTML omitted --> </blockquote> <p>...
