+:mod:`hmac` now accepts ``bytearray`` as well as ``bytes`` for the *key*
+argument to the :func:`~hmac.new` function, and the *msg* parameter to both the
+:func:`~hmac.new` function and the :meth:`~hmac.HMAC.update` method now

``python -m`` can now be used with namespace packages. (Contributed
by Brett Cannon in :issue:`18058`.)

+useful for implementing :meth:`.InspectLoader.get_source` methods.
