+    Rustworkx functions that return custom iterable objects, such as
+    :meth:`.PyDiGraph.node_indices`, now have an associated custom iterator object for these.  This
+    provides a speedup of approximately 40% for iterating through the custom iterables.
+
+    These types are not directly nameable or constructable from Python space, and other than the
+    performance improvement, the behavior should largely not be noticable from Python space.
