  ============================
  
+ - Through a bytecode optimizer bug (and I bet you didn't even know
+   Python *had* a bytecode optimizer :-), "unsigned" hex/oct constants
+   with a leading minus sign would come out with the wrong sign.
+   ("Unsigned" hex/oct constants are those with a face value in the
+   range sys.maxint+1 through sys.maxint*2+1, inclusive; these have
+   always been interpreted as negative numbers through sign folding.)
+   E.g. 0xffffffff is -1, and -(0xffffffff) is 1, but -0xffffffff would
+   come out as -4294967295.  This was the case in Python 2.2 through
+   2.2.2 and 2.3a1, and in Python 2.4 it will once again have that
+   value, but according to PEP 237 it really needs to be 1 in Python
+   2.2.3 and 2.3.  (SF #660455)
