  • Added missing upward gradient and right solid half patterns, upside-down diagonal halves, bottom half, and right half.
  • Changed the name of existing patterns according to Vexillology.
  • Can be used as fuel in furnaces.
Cobblestone stairs
  • Renamed "Stone Stairs" to "Cobblestone Stairs".
Daylight sensors
  • Can be inverted with a right click.
    • Reaches full strength at the opposite time than it would when set to normal.
    • This can allow for a light that turns on at night rather than day without the need of a NOT gate.
Ladders & Melons
  • Mined faster using axes.


  • Zoomed maps now snap to a grid rather than being centered on the original map.


  • Now take fall damage.
  • Now have sounds.
    • Have 'hurt', 'death', 'hop', and 'idle' sounds.
      • The 'hop' and 'idle' sounds are barely audible.
  • Changed model.
    • Added tail.

World generation[]

World border
  • The time parameter of the worldborder size changing can now be larger.
  • Only players get damage outside of the world border.

Command format[]

  • Can now be run in single player.
  • New arguments for debug /debug <start|stop|chunk> [<x> <y> <z>].
    • x/y/z are required and valid only for chunk mode.
    • May be removed, as the command was supposed to be dev only.[2]


  • Items which have been renamed will have their tooltips displayed as italic when highlighted, rather than just being straight.[3]
