We’ve just uploaded mypy 1.11 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)
Mypy now supports the new type parameter syntax introduced in Python 3.12 (PEP 695).
This feature is still experimental and must be enabled with the --enable-incomplete-feature=NewGenericSyntax flag, or with enable_incomplete_feature = NewGenericSyntax in the mypy configuration file.
We plan to enable this by default in the next mypy feature release.
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'
Type alias
type A[T] = C[list[T]]
This feature was contributed by Jukka Lehtosalo.
Support for functools.partial
Mypy now type checks uses of functools.partial. Previously mypy would accept arbitrary arguments.
#12446: Avoid calling @property (and other instance descriptors) during fixture discovery -- by asottile{.interpreted-text role="user"}
#12659: Fixed the issue of not displaying assertion failure differences when using the parameter --import-mode=importlib in pytest>=8.1.
#12667: Fixed a regression where type change in [ExceptionInfo.errisinstance]{.title-ref} caused [mypy]{.title-ref} to fail.
#12744: Fixed typing compatibility with Python 3.9 or less -- replaced [typing.Self]{.title-ref} with [typing_extensions.Self]{.title-ref} -- by Avasam{.interpreted-text role="user"}
#12745: Fixed an issue with backslashes being incorrectly converted in nodeid paths on Windows, ensuring consistent path handling across environments.
#6682: Fixed bug where the verbosity levels where not being respected when printing the "msg" part of failed assertion (as in assert condition, msg).
#9422: Fix bug where disabling the terminal plugin via -p no:terminal would cause crashes related to missing the verbose option.

Improved documentation
#12663: Clarify that the [pytest_deselected]{.title-ref} hook should be called from [pytest_collection_modifyitems]{.title-ref} hook implementations when items are deselected.
#12678: Remove erroneous quotes from [tmp_path_retention_policy]{.title-ref} example in docs.
Miscellaneous internal changes
