Minecraft Snapshot 18w15a

You’ve already seen the header image. Do we even need to say anything else?


  • New entity: Dolphins
  • New block: Conduit
  • New block: Blue Ice
  • New item: Heart of the Sea
  • New item: Nautilus Shell
  • Icebergs now generate in frozen oceans
  • You no longer have “night vision” effect underwater
  • Water now has different colours based on the biome
  • New video option: Biome blend distance
  • Going in and out of swimming should now feel smoother
  • You can now swim through 1×1 holes! Again!
  • Fog colour underwater now changes much smoother between biomes
  • Optimized fog rendering
  • Light now goes much further through liquid blocks


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 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)
