Version 8.4.3

• There was a new error, whoops.Fix for 8.4.2.

Version 8.4.2

• Added workaround for StackOverflowError. Hooray!!!
  There is a bug in CraftBukkit which causes your server to CRASH, when you shift+click an inventory item. This does not affect Chests. Only other kinds of containers, like dispensers and furnaces.
  This workaround makes sure players cannot shift+click inside treasure inventories.

You can't shift-click items inside treasures, other than chests. This is because of a Bukkit issue.
