    • Primed TNT no longer gives off particles.

Heads-up display
  • Hotbar now only contains 99 TNT and bookshelves.
  • Now get placed instead of eaten.[verify]


  • Placing an item into an armor slot, then taking it out and dropping it with an open inventory allows you to grab the armor sprite item. (see gallery)
    • Note that placing the sprite down causes it to disappear.
  • Dropped items sometimes glitch out creating an item that cannot be picked up, but attempting to causes the player to gain one of that item per tick (see gallery).


  • This is the last version released in 2009 and in the 2000s decade.
  • This is the first version to introduce items that do not correspond to blocks, which initiates the distinction between "items" and "blocks" in the game.
