be aware this is not a recommended build http://ci.bukkit.org/job/dev-CraftBukkit/1136/artifact/target/craftbukkit-0.0.1-SNAPSHOT.jar note: i would wait for the recommended build to come out
We've been playing on "unrecommended" builds for 2 days now. It's ok, a part from some bugs you can overcome and some lag that has been fixed it is playable. Some plugins did not work, but I think thats ok now, too. My suggestion is that if it is a pure survival server then go for it, if it is a plugin-heavy custom server then be aware that it might not work as intended.
