Java Edition 15w43a

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

World generation

 * Igloo
 * Spawn randomly in Ice Plains and Cold Taiga (but not the Hills variant).
 * Spawning parameters are shared with desert temples, 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, and loot chest, along with a villager priest and zombie villager priest in iron bars. A trapdoor with ladders leads down, into the mossy brick basement, cracked and stone brick also available, with 2 torches.
 * In the loot chest, there will sometimes be 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.

Command format

 * NBT tags
 * Chests/Minecart chests
 * : 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 will be affected.
