A backup is highly recommend before you install this update!
Changes:
Stored arena files are now readable (arena.yml) and can be changed outside the game. Old arena files get converted but not deleted! When it shows an error while converting the arena, post it in the comment section so that your old arena doesn't get lost.
Added game-win command and game-end settings which get executed by the console on game ending/winning. Also available for executing pet player.
