Looking to upgrade to 1.7.x Bukkit?

If you're looking to upgrade to 1.7.x CraftBukkit (Bukkit) then I have a wonderful tutorial for you. Bukkit has finally released the UNSUPPORTED build which may cause errors (none that I've occured yet.) In this tutorial it will show you how to either setup Bukkit 1.7.x with your hosted server or your personal server hosted off your PC.

I hope this helps, happy hunting!
