+* :class:`range` objects now support and *index* and *count* methods. This is
+  part of an effort to make more objects fully implement the :class:`collections.Sequence`
+  :term:`abstract base class`.  As a result, the language will have a more

+
+  In addition, :class:`range` objects now support slicing and negative indices.
+  This makes *range* more interoperable with lists.
