- Water physics were changed quite a lot:
- When simply walking in water, the player doesn't drop down as fast.
- Sneaking makes the player dive downward.
- Sprinting in water now puts the player in a swimming state, which makes them swim faster, and sets their height at 0.6.
- The speed and "area of effect" of flowing water now depends on its level. The player can jump out of water if it's low enough.
