Glowstone JE1.png Glowstone
  • Changed the material from "glass" to "stone".
    • This means the player would need a pickaxe to get resources from it.
    • This also means the player can now place redstone, torches, levers, etc. on the block.
  • Made glowstone drop more loot (2–4 glowstone dust).
  • Made the recipe sizes for creating glowstone smaller (2×2 instead of 3×3).

  • Can grow grass and flowers on grass blocks.

Non-mob entities[]

Oak Boat JE1.png Boats
  • Boats float up to the surface quicker.
  • Boats falling down into water lose their vertical momentum much faster.
  • Crashing into soul sand on a boat now kills the player, but keeps the boat intact.


3 bugs fixed

  • Fixed beds not working very well in Multiplayer.
  • Destroying a boat will no longer spawn the player too low, causing them to sometimes fall through the ground.
  • ⇧ Shift+ clicking a tool into a chest no longer restores it to new.
