21w42a is the sixth snapshot for Java Edition 1.18, released on October 20, 2021,[1] which introduces new music, changes to world generation, and many fixes related to spawning.

Additions[]

Items[]

Music Disc
  • Added a new music disc from Lena Raine titled "otherside".
    • Can be found on rare occasions in stronghold corridor chests, or much more rarely in dungeon chests.

General[]

Music
  • Added new music to the Overworld (when playing in survival mode), distributed to the new biomes, and to the main menu. [note 1]
    • By Lena Raine: "Stand Tall", "Left to Bloom", "One More Day", "Wending" and "Infinite Amethyst":
      • "Stand Tall" plays in the snowy slopes, jagged peaks, frozen peaks and stony peaks biomes, as well as the menu screen.
      • "Left to Bloom" plays in the meadow and lush caves biomes, as well as the menu screen.
      • "One More Day" plays in the meadow, snowy slopes and lush caves biomes, as well as the menu screen.
      • "Wending" plays in the grove, jagged peaks, stony peaks and dripstone caves biomes, as well as the menu screen.
      • "Infinite Amethyst" plays in the grove and dripstone caves biomes, as well as the menu screen.
    • By Kumi Tanioka (谷岡 久美): "Floating Dream", "Comforting Memories" and "An Ordinary Day":
      • "Floating Dream" plays in the jagged peaks and lush caves biomes.
      • "Comforting Memories" plays in the grove biome.
      • "An Ordinary Day" plays in the snowy slopes, dripstone caves and lush caves biomes.
Options
  • Added "Autosave Indicator" to video settings, for singleplayer worlds, which allows to toggle the indicator on / off.
    • The indicator appears in the bottom right of the screen whenever the game is saving the world file.
    • Defaults to on.
Particles
  • Added block_marker, to replace light and barrier.
    • Renders with texture declared in particle slot for model assigned to configured block state.
    • Summoned with same syntax as block particle (i.e. block_marker wheat[age=2]).

Changes[]

World generation[]

Ore distrubution
  • Increased top height limit of Badlands gold generation from Y=79 to Y=256, and increased the number of blobs.
Springs
  • Lava springs can now generate amid calcite, dirt, snow, powder snow and packed ice.
    • These changes allow lava springs to generate in mountains and snowy terrain.
  • Water springs don't generate higher than Y=192, and are slightly less common.

General[]

Player Spawning
  • Reworked world spawn selection algorithm.
    • Now spawns according to the same climate parameters that control biome placement and world generation: players should no longer be able to spawn in the ocean or some other inconvenient location.[needs in-game testing]
