+- Remove ``AcceptLanguageValidHeader``, ``AcceptLanguageNoHeader`` and
+  ``AcceptLanguageInvalidHeader``. These classes are consolidated into
+  ``AcceptLanguage`` with a ``header_state`` attribute for users that need
+  to know the state of the header.
+  See https://github.com/Pylons/webob/pull/463
+
+- Remove previously-deprecated ``webob.acceptparse.AcceptLanguage`` methods
+  ``__iter__``, ``__contains__``, ``best_match`` and ``quality``.
+  Look at using ``basic_filtering`` and ``lookup`` methods instead that
+  implement RFC-compliant algorithms for language negotiation.
