Minecraft 1.3.1 has been released, AADL server status
Minecraft 1.3.1 was released today. Until Bukkit updates their server mod to be compatible with 1.3.1, we'll be staying on 1.2.5.
If you've updated your Minecraft client and then connect to our server, you'll get told our server is outdated and then be disconnected.
If you're daring, you can check out a tool like MC Downgrader which is being updated for the 1.3.1 to 1.2.5 downgrade as I type this.
Otherwise, check out the updates and enjoy the new features of Minecraft while we wait for Bukkit.
