 In addition to the usual mapping methods, ordered dictionaries also support
 reverse iteration using :func:`reversed`.

+- collections.OrderedDict now supports a new method for repositioning
+  keys to either end.
+
 - Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest
   test cases now also have assertWarns and assertWarnsRegexp methods to
   check that a given warning type was triggered by the code under test.
