FYI, I have uploaded a release version of ZPatterns 0.4.3 to: http://www.zope.org/Members/pje/ZPatterns I have also updated the standalone PlugIns package at: http://www.zope.org/Members/pje/PlugIns These are primarily maintenance releases for GUI and security compatibility with Zope 2.3.x. The main added features are a 'DEPENDENT ON' clause for SkinScript 'WITH...COMPUTE' declarations, and support for the enhanced Zope 2.3 BTrees. Note that Zope 2.3.3 or better is required for either release. You do not need to download the seperate PlugIns release unless you are using PlugIns without ZPatterns, as the ZPatterns package already includes a copy of the PlugIns library. Please report any problems or concerns to the ZPatterns list, ZPatterns@eby-sarna.com (go to http://www.eby-sarna.com/mailman/listinfo/ZPatterns to subscribe). Thanks!
