Bukkit

Several major changes:

• Fixed a bug where signs would stop counting down at random times.
• Fixed a bug where queue signs would skip numbers when clicked on rapidly.
• Queues can now have a maximum size.
• Players are now removed from queues if they are teleported to another location.
• Completely overhauled the editing aspect for queues, changing the editing method from a mass of commands to a GUI.

Coming soon:

• Configurable sign content.
• Actionbar content (i.e. text overlay above the item bar) telling line members the status of the queue.
• Signs announcing waiting times for queues.

FOR ALL PEOPLE WHO ARE UPDATING FROM AUTOQUEUE V0.0.4 OR LESS:
AutoQueue v0.0.5 changed the way queues were saved, because of the new features that were added (queue size and redstone activation). This means that you will either have to delete your queues.yml and redefine your queues or add the following lines at the end of each configuration node:
  size: 10
  redstone: {}
If you don't choose one of these options, the plugin will generate errors.
