+- Dictionaries have a new class method, fromkeys(iterable, value=None).
+  It constructs a new dictionary with keys taken from the iterable and
+  all values set to a single value.  It is used for building membership
+  tests and for removing duplicates from sequences.
+
 - Added a new dict method pop(key).  This removes and returns the
   value corresponding to key.  [SF patch #539949]
