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.

Exclusion patterns can now be multi-line, thanks to Daniel Diniz <pull 1807_>. This enables many interesting exclusion use-cases, including those requested in issues 118 (entire files), 996 (multiple lines only when appearing together), 1741 (remainder of a function), and 1803 (arbitrary sequence of marked lines). See the multi_line_exclude section of the docs for more details and examples.
The JSON report now includes per-function and per-class coverage information. Thanks to Daniel Diniz for getting the work started. This closes issue 1793 and issue 1532.
Fixed an incorrect calculation of "(no class)" lines in the HTML classes report.

New features
#12231: Added [--xfail-tb]{.title-ref} flag, which turns on traceback output for XFAIL results.
If the [--xfail-tb]{.title-ref} flag is not given, tracebacks for XFAIL results are NOT shown.
The style of traceback for XFAIL is set with [--tb]{.title-ref}, and can be [auto|long|short|line|native|no]{.title-ref}.
Note: Even if you have [--xfail-tb]{.title-ref} set, you won't see them if [--tb=no]{.title-ref}.
Some history:
With pytest 8.0, [-rx]{.title-ref} or [-ra]{.title-ref} would not only turn on summary reports for xfail, but also report the tracebacks for xfail results. This caused issues with some projects that utilize xfail, but don't want to see all of the xfail tracebacks.
This change detaches xfail tracebacks from [-rx]{.title-ref}, and now we turn on xfail tracebacks with [--xfail-tb]{.title-ref}. With this, the default [-rx]{.title-ref}/ [-ra]{.title-ref} behavior is identical to pre-8.0 with respect to xfail tracebacks. While this is a behavior change, it brings default behavior back to pre-8.0.0 behavior, which ultimately was considered the better course of action.
#12281: Added support for keyword matching in marker expressions.
Now tests can be selected by marker keyword arguments.
Supported values are int{.interpreted-text role="class"}, (unescaped) str{.interpreted-text role="class"}, bool{.interpreted-text role="class"} & None{.interpreted-text role="data"}.
See marker examples <marker_keyword_expression_example>{.interpreted-text role="ref"} for more information.

#12567: Added --no-fold-skipped command line option.
If this option is set, then skipped tests in short summary are no longer grouped
by reason but all tests are printed individually with their nodeid in the same
way as other statuses.
