14w30a is the thirty-eighth snapshot for Java Edition 1.8, released on July 23, 2014,^[1][2] which adds banners.

Banners

• 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 results in a black pattern, one can 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.
• Can be worn as headgear (but only using commands).
• Top-most layer can be removed using cauldrons.

NBT format

• 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.

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 second skin layer no longer peeks through.
• Player and mob heads in inventories and held by mobs/players now display the actual head.

/summon

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

Lighting

• Completely fixed black spots.
• Players need to reload old worlds for them to be fixed.^[3]

Nether fortress

• Chests now have the possiblity of containing obsidian.

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 says something different if modded.​^{[more information needed]}
•  +  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.

Animations

• 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
• Items are now positioned a little higher and further left during their eating/drinking animation in first person view^[4]

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 if VBOs are disabled.
