We are still waiting on a 1.8 update for the server. However we have updated the server to allow 1.8 clients to connect. You may also connect with your 1.7 clients. We have also updated quite a few plugins in the process to better the performance of the server.
In the process of this update Disguise Craft has unfortunately broke and will remain that way until we can receive an update. If you find any bugs or problems, please report them on the forums so that we may address them.
