As per our policy, the following features have been deprecated in the 5.X series and are now
removed:

* The ``funcargnames`` read-only property of ``FixtureRequest``, ``Metafunc``, and ``Function`` classes. Use ``fixturenames`` attribute.

* ``@pytest.fixture`` no longer supports positional arguments, pass all arguments by keyword instead.

* Direct construction of ``Node`` subclasses now raise an error, use ``from_parent`` instead.
