Snapshot for



Client (.json)

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


  • Banners
    • Can be worn as head gear - but only using commands
    • Over 16*4006 possible combinations = 6.5536x1016
    • 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
  • NBT tags
    • New Silent tag for entities
      • Setting to 1 disables sound produced by that entity, such as idle and hurt sounds.
  • Statistics
    • 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


  • Commands
  • 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
  • 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
  • Lighting
    • Completely fixed black spots
    • You 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
