Blocks

 * Blocks that can be manually on farmland can now also be pushed into it by a piston without destroying the farmland.
 * Campfires can now be extinguished with a shovel.

Items

Entities

 * When breedable mobs in groups spawn naturally they sometimes spawn babies in the groups.
 * 5 or 10% chance depending on the animal.

General

 * Advancements
 * Item predicate in advancements now makes a distinction between actual enchantments and stored enchantments, like ones stored in enchanted books.
