I was being sloppy. I mean persistent objects where the class of the 
object can be defined to use descriptors for its members.

Ok. I assume "beta" means "feature freeze". So, if I want to back-port a 
feature from ZODB 4, and get that shipped with ZODB 3.3, I'll need to 
act fairly fast. What's the ZODB 3.3 branch called?

Do you know of any plans to make a ZODB 4 -> ZODB 3.3 storage migration 
script?
