 Bugs Fixed
 ++++++++++
 
+- Fixed the usage of pstats.Stats() output stream.  The
+  Control_Panel/DebugInfo/manage_profile ZMI view has been broken
+  since Python 2.5.  This breaks Python 2.4 compatibility when the
+  publisher-profile-file configuration option is set.
+
+- Use cProfile where possible for the
+  Control_Panel/DebugInfo/manage_profile ZMI view.
