Mypy Release Notes

Next release

Drop Support for Python 3.8

Mypy no longer supports running with Python 3.8, which has reached end-of-life. When running mypy with Python 3.9+, it is still possible to type check code that needs to support Python 3.8 with the --python-version 3.8 argument. Support for this will be dropped in the first half of 2025!

Contributed by Marc Mueller (PR 17492).

Mypyc accelerated mypy wheels for aarch64

Mypy can compile itself to C extension modules using mypyc. This makes mypy 3-5x faster than if mypy is interpreted with pure Python. We now build and upload mypyc accelerated mypy wheels for manylinux_aarch64 to PyPI, making it easy for users on such platforms to realise this speedup.

Contributed by Christian Bundy (PR mypy_mypyc-wheels#76)

--strict-bytes

By default, mypy treats an annotation of bytes as permitting bytearray and memoryview. PEP 688 specified the removal of this special case. Use this flag to disable this behavior. --strict-bytes will be enabled by default in mypy 2.0.

Contributed by Ali Hamdan (PR 18137) and Shantanu Jain (PR 13952).

Improvements to partial type handling in loops

This change results in mypy better modelling control flow within loops and hence detecting several issues it previously did not detect. In some cases, this change may require use of an additional explicit annotation of a variable.

Contributed by Christoph Tyralla (PR 18180).

(Speaking of partial types, another reminder that mypy plans on enabling --local-partial-types by default in mypy 2.0).

Mypy 1.14

We’ve just uploaded mypy 1.14 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features and bug fixes. You can install it as follows:

python3 -m pip install -U mypy
