 Version History
 ---------------
 
+  2.1: made some minor changes for compatibility with Python 3.0:
+        - replaced cmp with divmod and range with max in Calls.py
+          (cmp no longer exists in 3.0, and range is a list in
+          Python 2.x and an iterator in Python 3.x)
+
   2.0: rewrote parts of pybench which resulted in more repeatable
        timings:
         - made timer a parameter
