+:class:`difflib.SequenceMatcher` has a new parameter in its constructor,
+*autojunk*, that allows the user to turn off the automatic junk heuristic the
+class uses in its algorithm.  Additionally, two new attributes were exposed
+to users - *bjunk* and *bpopular*, allowing better understanding of the
+heuristics used by the class.
