Based on the # of moving stories and all the in-flight tasks which you can see here, Daniel, Patrick, myself and a few others talked offline and decided that we are not on track to release a beta tomorrow that meets the expectation.
So instead, we'll call tomorrow's release alpha-4, and delay beta, RC and GA all by one week. Wiki has been already updated. That means we are aiming to ship in April 6th now.
I'd like to call for those who are involved to spend the time from here to beta for nailing in-progress stories, testing, and fixing problems that are discovered. Feature freeze will happen tomorrow as originally planned. So no more new features beyond what's already in motion.
