Data version


17w48a[1] is the eighth snapshot released for Java Edition 1.13.


Command format[edit]

  • Tweaks to the command suggestion UI.
  • Reworked tab-completion for coordinates.
    • When not targeting a block, tab-completion now inserts the coordinates of the air the player is looking at 6 blocks away instead of ~ ~ ~.
    • Coordinates inserted will be block (integers) coordinates when the command used relates to blocks.


  • Custom recipes are now loaded from data packs in data/(namespace)/recipes/(name).json.
  • Turning off the vanilla data pack will also remove all recipes.
Death messages
  • Added death message for when the player is blown up by a bed in the nether or end.
    • "Player was killed by [Intentional Game Design]".
      • Clicking on "[Intentional Game Design]" opens a link to MCPE-28723.
