Changelog

7.0.1

=========================

Bug Fixes
---------

- `9608 <https://github.com/pytest-dev/pytest/issues/9608>`_: Fix invalid importing of ``importlib.readers`` in Python 3.9.


- `9610 <https://github.com/pytest-dev/pytest/issues/9610>`_: Restore `UnitTestFunction.obj` to return unbound rather than bound method.
Fixes a crash during a failed teardown in unittest TestCases with non-default `__init__`.
Regressed in pytest 7.0.0.


- `9636 <https://github.com/pytest-dev/pytest/issues/9636>`_: The ``pythonpath`` plugin was renamed to ``python_path``. This avoids a conflict with the ``pytest-pythonpath`` plugin.


- `9642 <https://github.com/pytest-dev/pytest/issues/9642>`_: Fix running tests by id with ``::`` in the parametrize portion.


- `9643 <https://github.com/pytest-dev/pytest/issues/9643>`_: Delay issuing a :class:`~pytest.PytestWarning` about diamond inheritance involving :class:`~pytest.Item` and
:class:`~pytest.Collector` so it can be filtered using :ref:`standard warning filters <warnings>`.
