I am surprised that there isn't more frustration here about essentially broken autobuilder. Because I definitely am frustrated about the situation.

At this point I would say it was a mistake to change autobuilder to new SDK so soon. Maybe it could still be reverted to the old SDK? Having 80% (number made up) of applications broken or not being able to upgrade them is not worth of anything what was intented with builder change.

At least I'm sure that next time we will wait for the real release.
