We’ve just uploaded mypy 1.12 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 Python 3.12 Syntax for Generics (PEP 695)
Support for the new type parameter syntax introduced in Python 3.12 is now enabled by default,
documented, and no longer experimental. It was available through a feature flag in
mypy 1.11 as an experimental feature.
This example demonstrates the new syntax:
# Generic function
def f[T](https://github.com/python/mypy/blob/master/x: T) -> T: ...
reveal_type(f(1)) # Revealed type is 'int'
Generic class
class C[T]:
def init(self, x: T) -> None:
self.x = x
c = C('a')
reveal_type(c.x) # Revealed type is 'str'
Black is now officially tested with Python 3.13 and provides Python 3.13
mypyc-compiled wheels. (#4436) (#4449)
Black will issue an error when used with Python 3.12.5, due to an upstream memory
safety issue in Python 3.12.5 that can cause Black's AST safety checks to fail. Please
use Python 3.12.6 or Python 3.12.4 instead. (#4447)
Black no longer supports running with Python 3.8 (#4452)
Stable style
Fix crashes involving comments in parenthesised return types or X | Y style unions.
(#4453)
Fix skipping Jupyter cells with unknown %% magic (#4462)
Preview style
Fix type annotation spacing between * and more complex type variable tuple (i.e. def fn(*args: *tuple[*Ts, T]) -> None: pass) (#4440)
Caching
Fix bug where the cache was shared between runs with and without --unstable (#4466)
Packaging
Upgrade version of mypyc used to 1.12 beta (#4450) (#4449)
blackd now requires a newer version of aiohttp. (#4451)
Output
Added Python target version information on parse error (#4378)
Add information about Black version to internal error messages (#4457)

- Implement dependency group support as defined in :pep:`735` - see :ref:`dependency_groups` - by :user:`gaborbernat`. (:issue:`3408`)
v4.21.2 (2024-10-03)
Bugfixes - 4.21.2
Include tox.toml in sdist archives to fix test failures resulting from its lack.
by :user:mgorny (:issue:3389)
v4.21.1 (2024-10-02)
Bugfixes - 4.21.1
- Fix error when using ``requires`` within a TOML configuration file - by :user:`gaborbernat`. (:issue:`3386`)
- Fix error when using ``deps`` within a TOML configuration file - by :user:`gaborbernat`. (:issue:`3387`)
- Multiple fixes for the TOML configuration by :user:`gaborbernat`.:
Do not fail when there is an empty command within commands.
Allow references for set_env by accepting list of dictionaries for it.
Do not try to be smart about reference unrolling, instead allow the user to control it via the extend flag,
available both for posargs and ref replacements.
The ref replacements raw key has been renamed to of. (:issue:3388)
v4.21.0 (2024-09-30)
Features - 4.21.0
Native TOML configuration support - by :user:gaborbernat. (:issue:999)

v4.20.0 (2024-09-18)
Features - 4.20.0
- Separate the list dependencies functionality to a separate abstract class allowing code reuse in plugins (such as
``tox-uv``) - by :gaborbernat`. (:issue:`3347`)
