As per our policy, the following features have been deprecated in the 4.X series and are now removed: * ``Request.getfuncargvalue``: use ``Request.getfixturevalue`` instead. * ``pytest.raises`` and ``pytest.warns`` no longer support strings as the second argument. * ``message`` parameter of ``pytest.raises``. * ``pytest.raises``, ``pytest.warns`` and ``ParameterSet.param`` now use native keyword-only syntax. This might change the exception message from previous versions, but they still raise ``TypeError`` on unknown keyword arguments as before. * ``pytest.config`` global variable. * ``tmpdir_factory.ensuretemp`` method. * ``pytest_logwarning`` hook. * ``RemovedInPytest4Warning`` warning type. * ``request`` is now a reserved name for fixtures.
