How exactly does Bukkit, the plugins, etc. work? Since Bukkit is not fully released or at least I don't believe so, there are constant updates correct? 1. Does this make plugins unavailable constantly or what? 2. Does it automatically update to the latest build or is that manual? What's required Bukkit, Craftbukkit, or both? The differences?
Yes there are constant updates. Yes plugins tend to break on certain updates. No, it doesn't automatically update. Bukkit is for devs, Craftbukkit is for servers.
