Hi, I'm just about to start writing the checkin logs for the merge of new-style ExtensionClass and ZODB 3.3 into the Zope 3 head. I expect the merge to be done within the next hour or two. Except for a test failure and some warnings pre-existing on the head, all of the tests and Zope runs. This is a huge change though and I expect this to be the beginning of a period of relative instability. Hoepfully, we can all work together to quickly address whatever problems come up. As I mentioned in another message, old Zope 2 databases won't work on the head for a while until I have a chance to come up with a mechanism for converting ancient BTrees and intSets. Unfortunately, until a change I checked into the Zope 2.7 branch on Wednesday, Zope was continuing to use the old depricated BTrees for a key data structure.
