The modules produce API warnings at startup, but they still continue to work like before and this is important since there are many people out there which are used to updating their software via RPM (or other packagers) and don't know how to compile source files. My comment about the API number bump was referring to using added functionality if available -- there could be #ifdef sections in the source files to enable/disable e.g. Unicode support. -- Marc-Andre Lemburg ______________________________________________________________________ Business: http://www.lemburg.com/ Python Pages: http://www.lemburg.com/python/
