Update: The server has been updated to support 1.7 and 1.8 clients. Remember, the 1.8 features are still not available on the server, but they will be in the future. I will let everyone know when the 1.8 features become available.
Mojang will be releasing Minecraft 1.8 September 2nd. With this update comes a large number of additions and changes to minecraft. As with any large update it will also require the updating of our server software and several of our plugins. It is not known at this time when everything will be updated to support 1.8.
As with many past updates we will be including support for 1.7 and 1.8 clients to connect to MutinyCraft. However, 1.8 features will not be accessible right away. Do not ask when the features will be added as that is not known at this time. When there is more information about when an update will take place it will be passed on to you.
