Bug Fixes
---------
- `#3671 <https://github.com/pytest-dev/pytest/issues/3671>`_: Fix ``filterwarnings`` not being registered as a builtin mark.
- `#3768 <https://github.com/pytest-dev/pytest/issues/3768>`_, `#3789 <https://github.com/pytest-dev/pytest/issues/3789>`_: Fix test collection from packages mixed with normal directories.
- `#3771 <https://github.com/pytest-dev/pytest/issues/3771>`_: Fix infinite recursion during collection if a ``pytest_ignore_collect`` hook returns ``False`` instead of ``None``.
- `#3774 <https://github.com/pytest-dev/pytest/issues/3774>`_: Fix bug where decorated fixtures would lose functionality (for example ``@mock.patch``).
- `#3775 <https://github.com/pytest-dev/pytest/issues/3775>`_: Fix bug where importing modules or other objects with prefix ``pytest_`` prefix would raise a ``PluginValidationError``.
- `#3788 <https://github.com/pytest-dev/pytest/issues/3788>`_: Fix ``AttributeError`` during teardown of ``TestCase`` subclasses which raise an exception during ``__init__``.
- `#3804 <https://github.com/pytest-dev/pytest/issues/3804>`_: Fix traceback reporting for exceptions with ``__cause__`` cycles.
Improved Documentation
----------------------
- `#3746 <https://github.com/pytest-dev/pytest/issues/3746>`_: Add documentation for ``metafunc.config`` that had been mistakenly hidden.
