 * ``bzrlib._static_tuple_c.StaticTuple`` is now available and used by
-  the btree index parser. This class functions similarly to ``tuple``
-  objects. However, it can only point to a limited collection of types.
-  (Currently StaticTuple, str, unicode, None, bool, int, long, float, and
-  not subclasses).  This allows us to remove it from the garbage collector
-  (it cannot be in a cycle), it also allows us to intern the objects. In
-  testing, this can reduce peak memory by 20-40%, and significantly
-  improve performance by removing objects from being inspected by the
-  garbage collector.  (John Arbash Meinel)
