In this release the Shape class has seen several changes:

New shapes have been added:

• CHISELED_BOOKSHELF
• COMPOSTER
• ENCHANTING
• SMITHING_NEW
• VILLAGER

Bugfixes:

• Shape.SHULKER_BOX is now a grid shape of 9x3 instead of 3x3.
• Fixed a bug in the Shape#determine(Inventory) method which caused it to return an incorrect shape for Villager inventories
• Removed methods that returned instances of internal classes from the Shape interface.
