Mypy Release Notes

Next Release

Remove Support for targeting Python 3.8

Mypy now requires --python-version 3.9 or greater. Support for only Python 3.8 is fully removed now. Given an unsupported version, mypy will default to the oldest supported one, currently 3.9.

This change is necessary because typeshed stopped supporting Python 3.8 after it reached its End of Life in October 2024.

Contributed by Marc Mueller (PR 19157, PR 19162).

Initial Support for Python 3.14

Mypy is now tested on 3.14 and mypyc works with 3.14.0b3 and later. Mypyc compiled wheels of mypy itself will be available for new versions after 3.14.0rc1 is released.

Note that not all new features might be supported just yet.

Contributed by Marc Mueller (PR 19164)

Deprecated Flag: --force-uppercase-builtins

Mypy only supports Python 3.9+. The --force-uppercase-builtins flag is now deprecated and a no-op. It will be removed in a future version.

Contributed by Marc Mueller (PR 19176)

Mypy 1.16

We’ve just uploaded mypy 1.16 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features 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.

Different Property Getter and Setter Types

Mypy now supports using different types for a property getter and setter:

class A:
    _value: int
@property

8.4.0

pytest 8.4.0 (2025-06-02)

Removals and backward incompatible breaking changes

• #11372: Async tests will now fail, instead of warning+skipping, if you don't have any suitable plugin installed.

• #12346: Tests will now fail, instead of raising a warning, if they return any value other than None.

• #12874: We dropped support for Python 3.8 following its end of life (2024-10-07).

• #12960: Test functions containing a yield now cause an explicit error. They have not been run since pytest 4.0, and were previously marked as an expected failure and deprecation warning.

  See the docs <yield tests deprecated>{.interpreted-text role="ref"} for more information.

Deprecations (removal in next major release)

• #10839: Requesting an asynchronous fixture without a [pytest_fixture_setup]{.title-ref} hook that resolves it will now give a DeprecationWarning. This most commonly happens if a sync test requests an async fixture. This should have no effect on a majority of users with async tests or fixtures using async pytest plugins, but may affect non-standard hook setups or autouse=True. For guidance on how to work around this warning see sync-test-async-fixture{.interpreted-text role="ref"}.

New features

• #11538: Added pytest.RaisesGroup{.interpreted-text role="class"} as an equivalent to pytest.raises{.interpreted-text role="func"} for expecting ExceptionGroup{.interpreted-text role="exc"}. Also adds pytest.RaisesExc{.interpreted-text role="class"} which is now the logic behind pytest.raises{.interpreted-text role="func"} and used as parameter to pytest.RaisesGroup{.interpreted-text role="class"}. RaisesGroup includes the ability to specify multiple different expected exceptions, the structure of nested exception groups, and flags for emulating except* <except_star>{.interpreted-text role="ref"}. See assert-matching-exception-groups{.interpreted-text role="ref"} and docstrings for more information.

• #12081: Added capteesys{.interpreted-text role="fixture"} to capture AND pass output to next handler set by --capture=.

• #12504: pytest.mark.xfail{.interpreted-text role="func"} now accepts pytest.RaisesGroup{.interpreted-text role="class"} for the raises parameter when you expect an exception group. You can also pass a pytest.RaisesExc{.interpreted-text role="class"} if you e.g. want to make use of the check parameter.

• #12713: New [--force-short-summary]{.title-ref} option to force condensed summary output regardless of verbosity level.

  This lets users still see condensed summary output of failures for quick reference in log files from job outputs, being especially useful if non-condensed output is very verbose.

• #12749: pytest traditionally collects classes/functions in the test module namespace even if they are imported from another file.

  For example:

  # contents of src/domain.py
  class Testament: ...
  contents of tests/test_testament.py
  from domain import Testament
  def test_testament(): ...

  In this scenario with the default options, pytest will collect the class [Testament]{.title-ref} from [tests/test_testament.py]{.title-ref} because it starts with [Test]{.title-ref}, even though in this case it is a production class being imported in the test module namespace.

  This behavior can now be prevented by setting the new collect_imported_tests{.interpreted-text role="confval"} configuration option to false, which will make pytest collect classes/functions from test files only if they are defined in that file.
