14w20a is the twenty-third snapshot released for Java Edition 1.8.


Command format[]

  • Can make text display on a players screen in the form of a title and/or subtitle.
    • /title <player> times <fadeIn> <stay> <fadeOut>
      • Set the fade in time, the stay on screen time and the fade out time for the title.
    • /title <player> title <raw json message>
      • Set and start showing the title.
    • /title <player> subtitle <raw json message>
      • Set and start the subtitle.
    • /title <player> clear
      • Clear titles immediately.
    • /title <player> reset
      • Reset all title parameters to defaults (fade times).


  • Added the following splashes:
    • "Run, coward! I hunger!"
    • "Blue warrior shot the food!"
    • "Warning! A huge battleship "STEVE" is approaching fast!"
    • "Rise from your grave!"



  • Blocks no longer have bits for metadata, the freed up bits are now used for block ids (dynamically).


  • "Slime sizing was moved to a post-spawn method, so the slime's canSpawn() method would report spawnability based on the initial size, not the final size. There is an added secondary check which fixes the issue."[1][2]

World generation[]

  • Now generate on the surface of desert, mesa, mega taiga and mushroom biomes.
World borders
  • If a player is stuck outside the world border, it is possible for them to freely fly/walk around (not possible to freely walk through the border).

Command format[]

  • Now has a selector argument.
    • Allows to print player's names.
    • Example: /tellraw @a {selector:"@a[team=TeamRed]"} will print everyone who is on TeamRed.
    • Also works with /title.


Spectator mode
  • Adjusting fly speed in spectator mode now works vertically too.
Player list
  • Made tab-list more consistent and a little prettier when using health display objective.
  • Now groups together teams.
  • Now sorts players by name.


Debug screen
  • The 'Towards Positive/Negative X/Z' is back.
