\nMypy Release Notes
\nNext release
\nMypy 1.11
\nWe’ve just uploaded mypy 1.11 to the Python Package Index (PyPI). Mypy is a static type\nchecker for Python. This release includes new features, performance\nimprovements and bug fixes. You can install it as follows:
\npython3 -m pip install -U mypy\n
\nYou can read the full documentation for this release on Read the Docs.
\nSupport Python 3.12 Syntax for Generics (PEP 695)
\nMypy now supports the new type parameter syntax introduced in Python\n3.12 (PEP 695).\nThis feature is still experimental and must be enabled with the\n--enable-incomplete-feature=NewGenericSyntax flag, or with\nenable_incomplete_feature = NewGenericSyntax in the mypy\nconfiguration file.\nWe plan to enable this by default in the next mypy feature release.
\nThis example demonstrates the new syntax:
\n# Generic function\ndef f[T](https://github.com/python/mypy/blob/master/x: T) -> T: ...\nreveal_type(f(1)) # Revealed type is 'int'
\nGeneric class
\nclass C[T]:\ndef init(self, x: T) -> None:\nself.x = x
\nc = C('a')\nreveal_type(c.x) # Revealed type is 'str'
\nType alias
\ntype A[T] = C[list[T]]\n
\nThis feature was contributed by Jukka Lehtosalo.
\nSupport for functools.partial
\nMypy now type checks uses of functools.partial.\nPreviously mypy would accept arbitrary arguments.
\nThis example will now produce an error:
\nfrom functools import partial\n</tr></table> \n
