Craftbukkit and Spigot are 1.7.2 ready. UnityCraft will update when we think it’s ok to update. Right now the chat isnt working, logfile isnt written, plugins don’t work. We will give the developers some time to fix bugs etc. and still give you a good game experience. We will probably update during next week. So for now, we will be running the 1.7.2 protocol hack 1.6.4 server.
