18w16a is the thirty-second snapshot for Java Edition 1.13, released on April 19, 2018^[1], which added the Buffet world type.

World types

• Buffet
  • Creates single-biome worlds.
  • Allows choosing between Overworld and End terrain generation.
  • Another way to generate chunks (checkerboard) is available by using an NBT Editor to open a Buffet world's level.dat, and using the following code for "generatorOptions":{"biome_source":{"type":"minecraft:checkerboard","biomes":[]},"chunk_generator":{"type":""}}.

Coral fans

• Now generate in coral reefs, on the sides of coral blocks.

Blue ice

• Is now slightly less slippery.

Coral blocks

• Now require Silk Touch to drop as items when mined, otherwise they drop dead coral blocks.
• No longer instantly turn into dead coral when on land.

Conduit

• Particles are now blue instead of orange.

Drowned

• Can now spawn extra in underwater ruins, besides their regular spawning in the oceans.

Water

• When water spreads and would later turn into a source block, it now immediately just places a source block instead of flowing into the block first.
  • This means that water can now also spread into waterloggable blocks.

Water Breathing

• When given from turtle shells, it no longer shows particles.

Optimizations

• Optimized world spawn position–finding code.

Block and item tags

• New valid_spawn block tag for blocks that the player can spawn on.
• New block and item tags for coral.

Ticks

• There is now a distinction between scheduled "liquid ticks" and "block ticks".

Biomes

• Changed how the temperature of ocean biomes is calculated; should result in nicer transitions between oceans.
• Biome names are now translatable.
• Updated some biome names:
