We have tested it as much as possible, but only on one machine and one version of Zope.
Updated documentation is forthcoming.
Also, we decided to roll back some of the changes that made PTK easier to install, for the sake of a quicker release. We'll get those back in there soon. It just mimics what the old architecture did. It could set the example for an implementation of ZODB-oriented skins. Have a good weekend, everyone.
