After much delay, snickering, and awe, Zope 2.7 final is out. I looked at beta 1 last July and liked what I saw. I haven't really used it since then because I like to keep a policy of not running on beta software (especially one with such a stretched out time table), but the general big new features remain the same.
I'm just looking forward to being able to finally use Python 2.3 libraries in our products. "New style classes" cannot be stored in the ZODB yet, but support for that should be coming shortly.
