15w43a is the thirty-fourth snapshot for Java Edition 1.9, released on October 21, 2015.^[1] Most notably, Chinese, Japanese and Korean (and likely other IME languages) can now be input into chat thanks to bug MC-2781 being fixed. Igloos were also added in this version.

👁 Image
Igloo

• Spawns randomly in ice plains and cold taiga (but not the hills variant).
  • Spawning parameters are shared with desert pyramids, jungle temples, and witch huts: the fact of a structure spawn is decided, then the biome determines which structure (if any) is spawned.
• Created by Searge (as found in the NBT data).
• An igloo contains: 9 white carpets, 3 light gray carpets, 2 blocks of ice, a redstone torch, a furnace, bed and a crafting table.
• Some igloos have a stone brick basement, with a cauldron, 2 red carpets, a brewing stand, 3 spruce stairs, 2 torches and a loot chest, along with a villager priest and zombie villager priest behind iron bars. An oak trapdoor with ladders leads down into the basement. Cracked and mossy stone bricks can also generate.
  • In the loot chest, there is sometimes a golden apple in the central spot, hinting that the player needs to cure the zombie.
  • Always spawns with a splash potion of Weakness, hinting the player to use these on the zombie villager to turn it into the same type of villager next to it.
  • The zombie has the PersistenceRequired tag which makes it not despawn.
  • Silverfish spawn in some stone brick blocks.

NBT format

• Chests/minecart chests
  • [String] LootTable: Loot table to be used to fill the chest when it is next opened or destroyed. When the chest is part of a double chest, only the half corresponding to the tagged single-chest is affected.
    • e.g. /setblock ~ ~1 ~ minecraft:chest 0 replace {LootTable:"minecraft:chests/simple_dungeon"}.
  • [Long] LootTableSeed: Seed for generating the loot table. Used in vanilla survival to replicate chest content in new worlds with same seeds. 0 or omitted uses a random seed.
    • /setblock x y z minecraft:chest 0 replace {LootTable:"chests/simple_dungeon",LootTableSeed:12345}.
• All mobs
  • [String] DeathLootTable (string): Determines which loot table is used when the mob is killed.
    • e.g. /summon Creeper ~ ~1 ~ {DeathLootTable:"minecraft:chests/simple_dungeon"}.
  • [Long] DeathLootTableSeed (long): The deterministic seed for grabbing data from the loot table. Used in vanilla survival to replicate chest content in new worlds with same seeds. Must not be 0.
    • e.g. /summon Creeper ~ ~1 ~ {DeathLootTable:"minecraft:chests/simple_dungeon",DeathLootTableSeed:123l}.

• Added LOLCAT.
• Replaced Australian English (Australia) with English (Australia). (Australian English had many jokes/slang, but English (Australia) is a real language.)

Loot tables

• All loot from mobs, chests etc. is now based on loot tables, excluding block drops.
  • Can be changed by mapmakers by adding a json file within the "WORLD/data/loot_tables" folder, however, it is broken in 43a.
