2.1 [Major Revision] Rewritten to use built-in container locking mechanism in 1.12
This release removes all CraftBukkit and NMS code and implemented functionality using built-in container locking mechanism in Minecraft 1.12 in order to provide portability and better block logger support. As a result, support for earlier Minecraft versions was removed as well as support for non-container blocks such as Doors, Trap Doors and Gates was removed.
Update Notes:
If you are upgrading the locks on all the containers will be lost, however a method for importing from the existing padlock dat files using /padlock import command is implemented, although not fully tested.
