  • Added a subtitle for fox teleporting, "Fox teleports".
  • Added subtitles for mules neighing and eating; "Mule neighs" and "Mule eats", respectively.

  • Several of these subtitles do not show up in game, but are specified in sounds.json.

Changes[edit]

Blocks[edit]

Redstone dust
  • Right-clicking an isolated redstone toggles it between a cross and a dot.
    • A dot of redstone does not power surrounding blocks, and a cross does.
    • Redstone which is connected to anything is not toggleable.
Stems
  • Now have a hardness of 1.

Items[edit]

Nether sprouts
  • Are now positioned in the center of the inventory slot as opposed to the bottom.

Mobs[edit]

Piglins
  • No longer walk around when admiring golden items.
  • If a piglin is hurt while admiring a gold ingot, the ingot now disappears without completing a barter.

World generation[edit]

Mineral veins
  • Increased the chance of ores to generate in the basalt deltas to balance against the reduced amount of netherrack in this biome.
World types

Command format[edit]

/locate
  • Structure names are now specified as lowercase.
/spreadplayers
  • Added the ability to control the height.
    • Syntax: /spreadplayers <center> <spreadDistance> <maxRange> under <maxHeight> <respectTeams> <targets>
      • maxHeight specifies the maximum height for resulting positions.

Gameplay[edit]

Fishing
  • Lily pads are now considered junk fishing loot rather than treasure.

General[edit]

Superflat
  • Removed structure settings from flat level preset strings as it was broken due to the addition of customizable worlds.
