1.6.4 was just released to the launcher! If you’re running CraftBukkit with plugins, we recommend waiting until they release a stable build before updating. If you don’t mind playing vanilla for a while, or you’re already running a vanilla Minecraft server, here’s how you can update:

  1. Stop your server
  2. Delete the jar/minecraft_server.jar file from your server via FTP. (Be sure you don’t have a custom JAR name, and be sure you’re deleting from the “jar” folder)
  3. Make sure your JAR file in Multicraft is set to the correct version; this should be “Minecraft (Vanilla)” for 1.6.4.
  4. Start your server!

If you’re running CraftBukkit 1.6.2 and you want to update to 1.6.4 dev, follow the above steps with “craftbukkit_beta.jar” and using the “CraftBukkit (Dev / Latest)” option in Multicraft.

If you’re running CraftBukkit and need to downgrade your client to play, follow these steps:

  1. Open Minecraft
  2. Click ‘Edit Profile’ in the launcher
  3. Select ‘Release 1.6.2’ in the ‘Use Version’ section
  4. Save and login!

If you run into any trouble, just submit a support ticket and we’ll get you set up.
