Changelog

Sourced from mypy's changelog.

Mypy 2.3.1

• Fix mypyc crash on double yielding Iterators (Daniël van Noord, PR 21826)
• Fix mypyc default_factory for inherited dataclass (Daniël van Noord, PR 21785)
• Clear mypyc coroutine env on coroutine completion (Piotr Sawicki, PR 21734)
• Fix crash when unpacking return value from overload (Shantanu, PR 21830)

Mypy 2.2

We've just uploaded mypy 2.2.0 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.

Support for Closed TypedDicts (PEP 728)

Mypy now supports closed TypedDicts as specified in PEP 728. A closed TypedDict cannot have extra keys beyond those explicitly defined. This allows the type checker to determine that certain operations are safe when they otherwise wouldn't be due to the potential presence of unknown keys.

You can use the closed keyword argument with TypedDict:

HasName = TypedDict("HasName", {"name": str})
HasOnlyName = TypedDict("HasOnlyName", {"name": str}, closed=True)
Movie = TypedDict("Movie", {"name": str, "year": int})
movie: Movie = {"name": "Nimona", "year": 2023}
has_name: HasName = movie  # OK: HasName is open (default)
has_only_name: HasOnlyName = movie  # Error: HasOnlyName is closed and Movie has extra "year" key
</tr></table>

Updates hatchling from 1.31.0 to 1.32.0

Release notes

Sourced from hatchling's releases.

Hatchling v1.32.0

Changed:

• Bump default core metadata version to 2.5

• Add tomlkit as a runtime dependency, which is required to rewrite pyproject.toml when setting a static version

Added:

• The version command can now set a version that is statically defined by the project.version field, updating pyproject.toml in place. Pass --force to allow an explicit downgrade

Fixed:

• Allow the ; private annotation on project.import-names and project.import-namespaces entries rather than rejecting them as invalid import names.

• Reject project.readme paths that are absolute or resolve outside of the project directory.
