• Rewrote almost all of the plugin
• Now supports bungeecord and velocity
• All messages can now be disabled by setting them to a blank string
• Made it easier for me to add permission plugins. With this, the first other one ive added is UltraPermissions, although it hasnt been tested. I still recommend using LuckPerms!
• Send actionbars and queue scoreboard events slightly more often to give a bit of a buffer for laggy players
• New feature: stayqueued. Give a player the permission ajqueue.stayqueued and they will stay queued for 60 seconds after leaving the server. Get ajQueuePlus to change the length
  
• The rewrite fixes all the issues that could occasionally cause the proxy to crash.
• Changed some of the permissions. See the new permissions on the wiki
• Better reload handling. Instead of leaving already existing queues there, it will instead delete the queue, the re-make it and re-add any players who were queued.
  
• A whole lot of internal changes that should make some things better for me

The only thing you should have to change when updating from 1.x.x to 2.x.x is changing to the new permissions
