+- Significant consolidation of ``Accept`` header handling into a single
+  ``AcceptHeader`` class.
+  See https://github.com/Pylons/webob/pull/460
+
+- ``webob.acceptparse.Accept.best_match`` is now a convenience method for
+  most use-cases where content-negotiation is needed server-side instead of
+  using ``acceptable_offers`` directly.

@@ -27,6 +36,25 @@ Backwards Incompatibilities
 
 - Drop support for Python 2.7, 3.4, 3.5, 3.6, and 3.7.
 
+- Remove ``AcceptValidHeader``, ``AcceptNoHeader`` and ``AcceptInvalidHeader``.
+  These classes are consolidated into ``AcceptHeader`` with a ``header_state``
+  attribute for users that need to know the state of the header.
+  See https://github.com/Pylons/webob/pull/460
+
+- Remove previously-deprecated ``webob.acceptparse.MIMEAccept``.
+  See https://github.com/Pylons/webob/pull/460
+
+- Remove previously-deprecated ``webob.acceptparse.Accept.__contains__``,
+  ``webob.acceptparse.Accept.__iter__``, and
+  ``webob.acceptparse.Accept.quality``.
+  See https://github.com/Pylons/webob/pull/460
+
+- Change behavior of ``webob.acceptparse.Accept.best_match`` to no longer
+  allow offers that are not mimetypes and to no longer allow offers with
+  server-side quality values. Logic is now normalized to use
+  ``webob.acceptparse.Accept.acceptable_offers``.
