Remove deprecated features

changelog/5180.removal.rst

@@ -0,0 +1,26 @@
+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.
+

+For more information consult
