<h1>Mypy Release Notes</h1>
<h2>Next Release</h2>
<h3>Remove Support for targeting Python 3.8</h3>
<p>Mypy now requires <code>--python-version 3.9</code> or greater. Support for only Python 3.8 is
fully removed now. Given an unsupported version, mypy will default to the oldest
supported one, currently 3.9.</p>
<p>This change is necessary because typeshed stopped supporting Python 3.8 after it
reached its End of Life in October 2024.</p>

<h3>Initial Support for Python 3.14</h3>
<p>Mypy is now tested on 3.14 and mypyc works with 3.14.0b3 and later.
Mypyc compiled wheels of mypy itself will be available for new versions after 3.14.0rc1 is released.</p>
<p>Note that not all new features might be supported just yet.</p>
<p>Contributed by Marc Mueller (PR <a href="https://redirect.github.com/python/mypy/pull/19164">19164</a>)</p>
<h3>Deprecated Flag: --force-uppercase-builtins</h3>
<p>Mypy only supports Python 3.9+. The --force-uppercase-builtins flag is now deprecated and a no-op. It will be removed in a future version.</p>
<p>Contributed by Marc Mueller (PR <a href="https://redirect.github.com/python/mypy/pull/19176">19176</a>)</p>
<h2>Mypy 1.16</h2>
<p>We’ve just uploaded mypy 1.16 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 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>Different Property Getter and Setter Types</h3>
<p>Mypy now supports using different types for a property getter and setter:</p>
<pre lang="python"><code>class A:
    _value: int
<pre><code>@Property
</code></pre>
<p>&lt;/tr&gt;&lt;/table&gt;
</code></pre></p>
