This TIP has not passed yet and though my vote was pragmatic, I really really hope we do not have to release without a well tested upgrade path.
Any one who has a site they can try upgrading and has time in the next week please do. Dave will be publishing new instructions probably tomorrow.
BTW: I consider decoupling of the .LRN release from OACS releases part of a move away from monolithic releases. I do not belive its a negative thing at all.
