:pep:`443` -- Single-dispatch generic functions
PEP written and implemented by Ćukasz Langa.
+A pure-python version of the :func:`~functools.partial` function is now in the
+stdlib; in CPython it is overridden by the C accelerated version, but it is
+available for other implementations to use. (Contributed by Brian Thorne in
+:issue:`12428`.)

+importlib
+---------
+
+The :class:`~importlib.abc.InspectLoader` ABC defines a new method,
+:meth:`~importlib.abc.InspectLoader.source_to_code` that accepts source
+data and a path and returns a code object. The default implementation
+is equivalent to ``compile(data, path, 'exec', dont_inherit=True)``.

+The following obsolete and previously deprecated APIs and features have been
+removed in Python 3.4:
* Support for the following operating systems has been removed from the source

been meaningless since Python 3.2, when the "new GIL" was introduced.
+* ``PyLoader`` and ``PyPycLoader`` have been removed from :mod:`importlib`.
