ZCO 0.5.1 and PCL 0.8.2 releases are available from http://sourceforge.net/project/showfiles.php?group_id=71074. The major new feature (see issue12 in the new issue tracker) will help new users properly configure their data stores.
The source for these projects has been moved to a Subversion repository hosted by Fort Collins' very own tummy.com, who do a lot of other great things for the Linux and Python communities. I've also moved from Sourceforge's issue tracker to a new tracker at http://sgillies.net:8900/primagis/ that is shared with PrimaGIS. It's filling up much faster than the old one.
