+html.entities
+-------------
+
+A new :data:`~html.entities.html5` dictionary that maps HTML5 named character
+references to the equivalent Unicode character(s) (e.g. ``html5['gt;'] == '>'``)
+has been added to the :mod:`html.entities` module.  The dictionary is now also
+used by :class:`~html.parser.HTMLParser`.

+html.parser
+-----------
+
+:class:`~html.parser.HTMLParser` is now able to parse broken markup without
+raising errors, therefore the *strict* argument of the constructor and the
+:exc:`~html.parser.HTMLParseError` exception are now deprecated.
+The ability to parse broken markup is the result of a number of bug fixes that
+are also available on the latest bug fix releases of Python 2.7/3.2.
