NEW BACKPACK!! The furnace backpack allows for smelting on the go.
new command, /bp vfurnace, lists all virtual furnaces (furnace backpacks that are currently smelting resources) and that vfurnaces current inventory location whether it be a player, chests, the ground, etc.
support for MC1.15 (meaning backpacks now supports 4 major MC versions)
you can now give yourself a backpack key through commands
better NMS code, now with soft-failing so backpacks should have expanded functionality on unsupported versions
added German to the list of supported translations
