<h1>Mypy Release Notes</h1>
<h2>Next Release</h2>
<h2>Mypy 1.17</h2>
<p>We’ve just uploaded mypy 1.17 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>Optionally Check That Match Is Exhaustive</h3>
<p>Mypy can now optionally generate an error if a match statement does
not
match exhaustively, without having to use
<code>assert_never(...)</code>. Enable
this by using <code>--enable-error-code exhaustive-match</code>.</p>
<p>Example:</p>
<pre lang="python"><code># mypy: enable-error-code=exhaustive-match
<p>import enum</p>
<p>class Color(enum.Enum):
RED = 1
BLUE = 2</p>
<p>def show_color(val: Color) -&gt; None:
# error: Unhandled case for values of type
&quot;Literal[Color.BLUE]&quot;
match val:
case Color.RED:
print(&quot;red&quot;)
</code></pre></p>
<p>This feature was contributed by Donal Burns (PR <a
href="https://redirect.github.com/python/mypy/pull/19144">19144</a>).</p>
<h3>Further Improvements to Attribute Resolution</h3>
<p>This release includes additional improvements to how attribute types
and kinds are resolved. These fix many bugs and overall improve
consistency.</p>
<ul>
<li>Handle corner case: protocol/class variable/descriptor (Ivan
Levkivskyi, PR <a
href="https://redirect.github.com/python/mypy/pull/19277">19277</a>)</li>
<li>Fix a few inconsistencies in protocol/type object interactions (Ivan
Levkivskyi, PR <a
href="https://redirect.github.com/python/mypy/pull/19267">19267</a>)</li>
<li>Refactor/unify access to static attributes (Ivan Levkivskyi, PR <a
href="https://redirect.github.com/python/mypy/pull/19254">19254</a>)</li>
<li>Remove inconsistencies in operator handling (Ivan Levkivskyi, PR <a
href="https://redirect.github.com/python/mypy/pull/19250">19250</a>)</li>
<li>Make protocol subtyping more consistent (Ivan Levkivskyi, PR <a
href="https://redirect.github.com/python/mypy/pull/18943">18943</a>)</li>
