<h1>Mypy Release Notes</h1>
<h2>Next Release</h2>
<p>...</p>
<h2>Mypy 1.15</h2>
<p>We’ve just uploaded mypy 1.15 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>Performance Improvements</h3>
<p>Mypy is up to 40% faster in some use cases. This improvement comes largely from tuning the performance
of the garbage collector. Additionally, the release includes several micro-optimizations that may
be impactful for large projects.</p>

<h3>Mypyc Accelerated Mypy Wheels for ARM Linux</h3>
<p>For best performance, mypy can be compiled to C extension modules using mypyc. This makes
mypy 3-5x faster than when interpreted with pure Python. We now build and upload mypyc
accelerated mypy wheels for <code>manylinux_aarch64</code> to PyPI, making it easy for Linux users on
ARM platforms to realise this speedup -- just <code>pip install</code> the latest mypy.</p>

<h3><code>--strict-bytes</code></h3>
<p>By default, mypy treats <code>bytearray</code> and <code>memoryview</code> values as assignable to the <code>bytes</code>
type, for historical reasons. Use the <code>--strict-bytes</code> flag to disable this
behavior. <a href="https://peps.python.org/pep-0688">PEP 688</a> specified the removal of this
special case. The flag will be enabled by default in <strong>mypy 2.0</strong>.</p>
