(9/9/14) - Pets are now back! Sorry for the long wait, Things still may be glitchy so please report any bugs. Currently zombies, endermen, and pigmen pets are disabled due to them crashing clients. This should be fixed soon.
You may connect to the server with either a 1.7.10 or a 1.8 client. We're running a build of Spigot that allows us to accept 1.8 clients, without any 1.8 features. We still have to wait for a bukkit update to get the new features.
A few things broke when installing the protocol build:
Basically anything that is tricking the client into seeing things, broke. We're still working on getting these updated. For those with a pet, don't worry you still have your pet, It's all saved and you'll get it once the plugin updates.
