As the title says, 1.7.2 is released.
However, we are of course going to stay on 1.6.4 until we have the new server/map ready to go. We will not be going to a temporary map Because Bukkit is slow, we are. So, go and enjoy your last moments being able to build on the current MCAU map before we made it a read-only map. It will be accessible from within the Event/Creative server, just like the two previous maps.
We’ll make another announcement once we’re up and running on 1.7.2
