Minecraft 1.16.2 : Snapshot 20w28a

Today, the second snapshot of Minecraft version 1.16.2, the 20w28a, is now available in your launcher. It fixes various bugs and adds experimental support for custom biomes.
Additions and modifications :

  • The black rock can now be used to make a still.
  • Villagers emit green particles when they join a village, when they set up a bed and when they get a profession.
  • Immortality totems now give a 40s fire resistance effect upon activation.
  • Changes to the loot obtained through barter.
    • A Piglin can now give a vial of water, black rock or a spectral arrow against a gold ingot.
    • This change makes black rock renewable.
  • A Piglin no longer gives a cream of magma or luminous powder in exchange for a gold ingot.
  • Addition of an experimental support for customized biomes.
    • Addition of a “worldgen” folder for data packs.
      • worldgen/biome can contain biome definitions.
