Protocol version


13w04a is the sixth snapshot released for Java Edition 1.5.[1]



  • Mobs now show the name given to them, either by anviling on their Spawn Egg or external editors, above their head when the player. looks directly at them within a circular 6 block radius.

Command format[edit]

  • A new command feature.
  • Not 100% done yet.
  • The scoreboard can be used to track deaths, players killing another player, players killing something a mob, or players activating commands.
  • The complicated system uses a combination of name, display name, and criteria, and track an integer number of points for players.



Command blocks
  • Now use their name instead of @ in the chat.
  • Now can face in all directions.
  • Now equip players with armor from one block away.
  • They now activate TNT.
  • They now use bone meal.
  • They now use flint and steel.
  • Now can face in all directions.
Redstone Comparators
  • Can now be used with jukeboxes.
  • Output signal strength relates to the disk number.
  • 43:8 will now be the "smooth stone full half-slab block" and will remain so.
  • Generally: If the top bit is set, the top texture will be used on all sides, also allowing for smooth sandstone full half-slab blocks (43:9).


  • Held armor can be equipped by right-clicking.
    • In this particular snapshot, this functionality is very faulty, prone to crashing and incorrect slot usage.
    • It will be fixed in the next snapshot.
  • No longer gives instant growth – instead, each use advances one growth stage:
  • Gives off green particles when used.
  • Note: Dinnerbone has stated that he still has to balance out this new bonemeal growth system.[2]


  • Mobs will not actively path over rails.


  • The player can now hit mobs/players from five blocks away.
