<h1>Mypy Release Notes</h1>
<h2>Next Release</h2>
<h2>Mypy 2.4</h2>
<p>We've just uploaded mypy 2.4.0 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 3.15 Support</h3>
<p>Mypy 2.4 supports running on Python 3.15 and type checking most Python
3.15 features. This includes the new builtin <code>sentinel</code> type for
sentinel values (PEP 661), which mypy now supports (see below for
details). Lazy imports (PEP 810) and unpacking in comprehensions
(PEP 798) are also supported. Closed TypedDicts (PEP 728) have been
supported since mypy 2.2, but the <code>extra_items</code> TypedDict argument,
also introduced in PEP 728, is still unsupported. Support for
<code>extra_items</code> will be added in a future mypy release.</p>
<h3>Native Parser Enabled by Default</h3>
<p>Mypy now uses the new native parser by default. It's based on the Ruff
parser, and it's significantly faster than the legacy parser, which
uses the stdlib <code>ast</code> module. The native parser also has other
benefits:</p>
<ul>
<li>You can target newer Python versions and use recent Python syntax
even when running mypy on an older Python version. For example, you
can use <code>--python-version 3.15</code> when running mypy on Python 3.14.</li>
<li>Stub files can use syntax that is newer than the target Python
version. For example, stubs can use the PEP 695 generic class syntax
(<code>class Box[T]: ...</code>) when running on or targeting Python 3.10.</li>
<li>Parallel type checking requires the native parser.</li>
</ul>
<p>The legacy parser is still available through <code>--no-native-parser</code>, or
<code>native_parser = False</code> in the config file (<code>native_parser = false</code>
under <code>[tool.mypy]</code> in pyproject.toml). We are planning to remove the
legacy parser in early 2027. If you run into a problem with the native
parser, please report it on the
<a href="https://github.com/python/mypy/issues">issue tracker</a>.</p>
<p>Unlike the legacy parser, the native parser doesn't support type
comments for variables defined by <code>for</code> and <code>with</code> statements. These
type comments are silently ignored, and the types of the variables are</p>
