Protocol version


14w30a is the thirty-eighth snapshot for Java Edition 1.8.[1]



  • Can be worn as headgear - but only using commands.
  • Over 16×4006 possible combinations = 6.5536×1016.
  • Crafted like a sign, just with one color of wool instead of planks.
  • Can be stacked to 16.
  • Most patterns are created by arranging dyes in certain ways around a banner on a crafting table.
    • The dyes cannot be shifted or flipped even if there is space, known as a fixed recipe.
  • Additional patterns: creeper, skull & crossbones, brick, and flower - making these without dyes will result in a black pattern, use dyes to get different colors (items: creeper skull, wither skeleton skull, brick block, oxeye daisy).
  • 33 crafting recipes which produce different patterns.
  • Up to 6 layers of patterns possible.
  • Can be placed on walls or on the ground (16 rotations possible).
  • Sway as if blown by wind.
  • Can be cloned by crafting them together with a blank banner.
  • Top-most layer can be removed using cauldrons.

Command format[]

NBT tags
  • New Silent tag for entities.
    • Setting to 1 disables sound produced by that entity, such as idle and hurt sounds.


  • stat.talkedToVillager
    • Detects how many times the player has talked to villagers (opened the trading GUI).
  • stat.tradedWithVillager
    • Detects how many times the player has traded with villagers.



Mob Heads
  • Made creeper, skeleton and zombie heads available in survival.
  • Creepers, skeletons, wither skeletons, and zombies drop their heads when killed by charged creepers. Wither skeletons continue to have heads as rare drops.
  • Skulls worn on heads are now bigger so the 2nd skin layer no longer peeks through.
  • Player and mob heads in inventories and held by mobs/players now display the actual head.

Command format[]

  • /summon command can now summon lightning using /summon LightningBolt.


  • Completely fixed black spots.
  • Players will need to re-load old worlds for them to be fixed.[2]


F3 debug screen
  • Now displays how many chunk sections are being rendered currently and how many chunk sections are out of view in percent, the OpenGL version, display size, vendor and GPU.
  • "Vanilla" added to the version number. e.g., "Minecraft 14w30b (14w30b/Vanilla)".
    • Presumably this will say something different if modded. Very few mods (or even APIs) currently exist for versions this recent.
  • F3+H tooltips now show how many NBT tags an item has.
  • Block names no longer contain blockstate data in brackets next to their name (in the view of a block's name and data along the right side of the screen).
  • Data is still shown in separate rows beneath the name.
  • Third person sword blocking position slightly tweaked
  • Block hitting animation redone
  • Punching while blocking, shooting an arrow, drinking a potion, and eating removed
  • Rod scaling tweaked
  • Removed armor turning red when hit
  • Video Settings
    • Render distance slider now goes up to 32 when using 64-bit Java.
      • Requires 2 GB of allocated RAM.
    • Removed Advanced OpenGL.
  • Performance improvements
    • Rewrote chunk sorting.
    • Ported over the visibility culling code from MCPE to avoid rendering invisible stuff.
    • Threaded chunk rebuilds.


Distance effects
  • Chunks detach and jitter at high coordinates.
