+xml.etree.ElementTree
+---------------------
+
+The :mod:`xml.etree.ElementTree` module now imports its C accelerator by
+default; there is no longer a need to explicitly import
+:mod:`xml.etree.cElementTree` (this module stays for backwards compatibility,
+but is now deprecated).  In addition,  the ``iter`` family of methods of
+:class:`~xml.etree.ElementTree.Element` has been optimized (rewritten in C).
+The module's documentation has also been greatly improved with added examples
+and a more detailed reference.
