<h1>Mypy Release Notes</h1>
<h2>Next release</h2>
<p>Stubgen will now include <code>__all__</code> in its output if it is
in the input file (PR <a
href="https://redirect.github.com/python/mypy/pull/16356">16356</a>).</p>
<h2>Mypy 1.7</h2>
<p>We’ve just uploaded mypy 1.7 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>
<h4>Using TypedDict for <code>**kwargs</code> Typing</h4>
<p>Mypy now has support for using <code>Unpack[...]</code> with a
TypedDict type to annotate <code>**kwargs</code> arguments enabled by
default. Example:</p>
<pre lang="python"><code># Or 'from typing_extensions import ...'
from typing import TypedDict, Unpack
<p>class Person(TypedDict):
name: str
age: int</p>
<p>def foo(**kwargs: Unpack[Person]) -&gt; None:
...</p>
<p>foo(name=&quot;x&quot;, age=1)  # Ok
foo(name=1)  # Error
</code></pre></p>
<p>The definition of <code>foo</code> above is equivalent to the one
below, with keyword-only arguments <code>name</code> and
<code>age</code>:</p>
<pre lang="python"><code>def foo(*, name: str, age: int) -&gt; None:
    ...
</code></pre>
<p>Refer to <a href="https://peps.python.org/pep-0692/">PEP 692</a> for
more information. Note that unlike in the current version of the PEP,
mypy always treats signatures with <code>Unpack[SomeTypedDict]</code> as
equivalent to their expanded forms with explicit keyword arguments, and
there aren't special type checking rules for TypedDict arguments.</p>
<p>This was contributed by Ivan Levkivskyi back in 2022 (PR <a
href="https://redirect.github.com/python/mypy/pull/13471">13471</a>).</p>
<h4>TypeVarTuple Support Enabled (Experimental)</h4>
<p>Mypy now has support for variadic generics (TypeVarTuple) enabled by
default, as an experimental feature. Refer to <a
href="https://peps.python.org/pep-0646/">PEP 646</a> for the
details.</p>
<p>TypeVarTuple was implemented by Jared Hance and Ivan Levkivskyi over
several mypy releases, with help from Jukka Lehtosalo.</p>
