DOLPHINS
It's happening!

- Spawns in any ocean that isn't frozen
- They're just cute, okay?
- Dolphins are very playful and love floating items
- They also love to chase after boats
- If you upset one, you upset them all
- More behaviours coming soon

WATER
Blubb blubb blubb blubb

Water now only blocks 1 light per block, instead of 3
This only affects newly placed water - we will relight all chunks in an upcoming snapshot
Every ocean biome has a unique water colour, and swamps are icky and gross
In newly generated chunks, you're less likely to find frozen ocean next to warm ocean (and similar)
CONDUIT
?????

????
I'm not sure.
What is this?
Where are we?
