 Core and builtins
 
+- Complex numbers supported divmod() and the // and % operators, but
+  these make no sense.  Since this was documented, they're being
+  deprecated now.
+
 - String methods lstrip(), rstrip() and strip() now take an optional
   argument that specifies the characters to strip.  For example,
   "Foo!!!?!?!?".rstrip("?!") -> "Foo".
