Mypy 1.15

We’ve just uploaded mypy 1.15 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:

python3 -m pip install -U mypy

You can read the full documentation for this release on Read the Docs.

Performance Improvements

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.

Mypyc Accelerated Mypy Wheels for ARM Linux

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 manylinux_aarch64 to PyPI, making it easy for Linux users on ARM platforms to realise this speedup -- just pip install the latest mypy.

Contributed by Christian Bundy and Marc Mueller (PR mypy_mypyc-wheels#76, PR mypy_mypyc-wheels#89).

--strict-bytes

By default, mypy treats bytearray and memoryview values as assignable to the bytes type, for historical reasons. Use the --strict-bytes flag to disable this behavior. PEP 688 specified the removal of this special case. The flag will be enabled by default in mypy 2.0.

Contributed by Ali Hamdan (PR 18263) and Shantanu Jain (PR 13952).

Improvements to Reachability Analysis and Partial Type Handling in Loops
