Dripstone cluster Dripstone caves No No A large vertical cluster of dripstone blocks.

Changed

Name Image Changed
All structures Now hardcoded into world generation.
General
  • The Overworld now uses the multi-noise biome source type.
  • Terrain generation is now independent from biomes, with biomes adapting to whatever terrain they happen to generate throughout.
    • This allows for natural variation in the terrain of any individual biome, both in terms of shape and elevation.
      • For example, forests and deserts could form up on a hill without needing a special biome just for that purpose.
    • This additionally allows for smoother transitions between biomes.
  • Terrain is now smoother and more extreme.
  • Bedrock layers generate dependent on the world seed now.
  • New random number generator is used for Overworld generation.
Amethyst geode Now generate only up to Y=30.
Azalea tree Now generate above lush caves.
Fossil Generates with deepslate diamond ore instead of coal ore when below Y=0.
Lakes
  • Water lakes were removed, because aquifers could provide local water levels.
  • Lava lakes now generate above Y=0.
Stony shore
  • Now generates with strips of gravel.
  • Can generate alongside any biome instead of just windswept hills.
Desert pyramid
  • No longer generate on water.
  • Now spawn on the surface rather than at a fixed Y-level, but tend to be partially buried.
Monster room Increased the amount of dungeons, especially below Y=0.
Buried treasure
Can now contain Water Breathing potions.
Mineshaft
  • The starting room no longer generates with a dirt floor.
  • Now generate higher up in badlands.
Pillager outpost Now generate in all the new mountain biomes.
Village
  • Now slightly more spread out.
  • Now generate in meadows.

  • Contains larger deposits of copper ore.
Lush caves
  • An azalea tree generates on the surface to indicate the biome's location.
  • Terrain is covered with lots of moss and clay.

Advancements

IconAdvancementIn-game descriptionActual requirements (if different)
Caves & CliffsFree fall from the top of the world (build limit) to the bottom of the world and surviveFall from at least Y=319 to at most Y=-59 with a vertical distance of greater than 379 blocks. Jumping before the fall is not recommended as it tends to not award the advancement.
Feels Like HomeTake a Strider for a loooong ride on a lava lake in the OverworldWhile riding a strider, travel 50 blocks on lava in the Overworld.
Only horizontal displacement is counted. Traveling in a circle for more than 50 blocks doesn't count.
Sound of MusicMake the Meadows come alive with the sound of music from a JukeboxUse a music disc on a jukebox that stands within a meadow biome.
Star TraderTrade with a Villager at the build height limitStand on any block that is higher than 318 and trade with a villager or wandering trader.
