class Pet(Enum):
CAT = 1 # Member attribute
DOG = 2 # Member attribute
WOLF: int = 3 # New error: Enum members must be left unannotated
species: str # Considered a non-member attribute
In particular, the specification change can result in issues in type stubs (.pyi files), since
historically it was common to leave the value absent:
# In a type stub (.pyi file)
class Pet(Enum):
# Change in semantics: previously considered members, now non-member attributes
CAT: int
DOG: int
# Mypy will now issue a warning if it detects this situation in type stubs:
# > Detected enum "Pet" in a type stub with zero members.
# > There is a chance this is due to a recent change in the semantics of enum membership.
# > If so, use `member = value` to mark an enum member, instead of `member: type`
class Pet(Enum):
# As per the specification, you should now do one of the following:
DOG = 1 # Member attribute with value 1 and known type
WOLF = cast(int, ...) # Member attribute with unknown value but known type
LION = ... # Member attribute with unknown value and unknown type

Mypy 1.13
We’ve just uploaded mypy 1.13 to the Python Package Index (PyPI).
Mypy is a static type checker for Python. You can install it as follows:
Fix: nested context managers could incorrectly be analyzed to flag a missing branch on the last context manager, as described in issue 1876. This is now fixed.
Fix: the missing branch message about not exiting a module had an extra “didn’t,” as described in issue 1873. This is now fixed.
Fix: a final wildcard match/case clause assigning to a name (case _ as value) was incorrectly marked as a missing branch. This is now fixed, closing issue 1860.
Fewer things are considered branches now. Lambdas, comprehensions, and generator expressions are no longer marked as missing branches if they don’t complete execution. Closes issue 1852.
Fix: the HTML report didn’t properly show multi-line f-strings that end with a backslash continuation. This is now fixed, closing issue 1836, thanks to LiuYinCarl and Marco Ricci.
Fix: the LCOV report now has correct line numbers (fixing issue 1846) and better branch descriptions for BRDA records (fixing issue 1850). There are other changes to lcov also, including a new configuration option line_checksums to control whether line checksums are included in the lcov report. The default is false. To keep checksums set it to true. All this work is thanks to Zack Weinberg (pull 1849 and pull 1851).
Fixed the docs for multi-line regex exclusions, closing issue 1863.
Fixed a potential crash in the C tracer, closing issue 1835, thanks to Jan Kühle.

#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
