'''14w30a''' is the thirty-eighth [[Minecraft:snapshot]] for [[Minecraft:Java Edition 1.8]], released on July 23, 2014,<ref>{{cite|url=https://web.archive.org/web/20140727061744/https://mojang.com/2014/07/minecraft-snapshot-14w30a/|title=Minecraft snapshot 14w30c|date=July 23, 2014|website=Mojang.com|author=[[Minecraft:Dinnerbone]]}}</ref><ref>{{tweet|Dinnerbone|491937730931093505|Here's a minecraft snapshot, hot and fresh from the oven!|July 23, 2014}}</ref> which adds [[Minecraft:banner]]s.

== Additions ==
=== Blocks ===
'''[[Minecraft:Banner]]s'''
* Over 16×400<sup>6</sup> possible combinations – 6.5536×10<sup>16</sup>.
* 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.

=== Command format ===
'''[[Minecraft:NBT format]]'''
* New <code>Silent</code> tag for entities.
** Setting to 1 disables sound produced by that entity, such as idle and hurt sounds.

=== General ===
'''[[Minecraft:Statistics]]'''
* <code>stat.talkedToVillager</code>
** Detects how many times the player has talked to villagers (opened the trading GUI).
* <code>stat.tradedWithVillager</code>
** Detects how many times the player has traded with villagers.

== Changes ==
=== Blocks ===
'''[[Minecraft:Mob head]]s'''
* 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 [[Minecraft: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.

=== Command format ===
'''{{cmd|summon}}'''
* {{cmd|summon}} command can now summon lightning using {{cmd|summon LightningBolt}}.

=== Gameplay ===
'''Lighting'''
* Completely fixed black spots.
* Players need to reload old worlds for them to be fixed.<ref>{{tweet|SeargeDP|491938604827295744|Black shadow patches are not automatically fixed in existing worlds, but should not show up anymore on new worlds and chunks.|July 23, 2014}}</ref>

=== World generation ===
'''[[Minecraft:Nether fortress]]'''
* Chests now have the possiblity of containing obsidian.

=== General ===
'''F3 [[Minecraft:debug screen]]'''
* Now displays how many chunk sections are being rendered currently and how many chunk sections are out of view in percent, the [[Minecraft:wikipedia:OpenGL|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 info}}
* {{key|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.
'''Animations'''
* Third person sword [[Minecraft: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<ref>{{bug|MC-273056}}</ref>

'''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.

== Bugs ==
'''[[Minecraft:Java Edition distance effects/Historical effects|Distance effects]]'''
* Chunks detach and jitter at high coordinates if VBOs are disabled.
