- Emits a strong glow, at light level 15.
- Heart of the Sea
- Used to craft conduits.
- Not available currently in survival.
- Nautilus Shell
- Spawn in any ocean that isn't frozen.
- Neutral mobs. Like wolves and zombie pigmen, dolphins will attack in groups if one is angered.
- Can be fed using raw cod, but they don't breed.
- Drop cod on death.
- Play with nearby items by picking them up and dropping them after a very short moment.
- Occasionally jump out of water like real-life dolphins.
- Can also jump between disconnected bodies of water.
- Chase after boats and jump over water surfaces.
- Suffocate after spending too much time on land.

- Conduit Power
- Given when a conduit is activated.
- Stops the breath meter from running out, gives underwater night vision and increases mining speed.
- When active at full power, the range will increase and hostile mobs within 8 blocks will take damage.
- Added 'Biome Blend' distance video option.
- Mobs can now spawn on top of ice.
- Has a new texture.
- Now only blocks 1 light per block, instead of 3.
- This only affects newly placed water.
- Underwater vision from previous snapshots is gone; water is darker at lower depths.
- Ocean variants have their own water colors, and the swamp water color has been changed.
- In newly generated chunks, it's less likely to find frozen oceans next to warm oceans, etc.
- It is now possible to swim through one block holes again.
- The transition between swimming and normal state is now smoother.
- Sprinting at the surface of water no longer makes you swim, instead you stay at the same altitude constantly.
- Optimized fog rendering.
