Additions

General

New water physics
Water can be placed in chests, trapped chests, stairs, slabs, fences, walls, iron bars, and glass panes.
Water can flow out these blocks, but can not flow into them.
When full of water, they will count as water blocks for all gameplay (such as swimming).
Water will flow out of all faces of the block.
Removed the blocks flowing_water and flowing_lava.
Removed the block tags water_hacked and waterlogged.
All of the blocks that water can be placed in now have the block state waterlogged.
Blocks such as bubble column or kelp will always count as a water source.

Changes

Mobs
Phantoms are now considered undead mobs
This means that they are harmed by Healing potions, healed by Harming potions, ignored by the wither, and affected by Smite enchantment.
