15w38a is the twenty-fourth snapshot released for 1.9.

Additions

 * Statistics
 * Added "Times Slept in a Bed".

Changes

 * Mobs
 * Further improvements to general mob AI.


 * Skeletons
 * Skeletons can now walk, strafe and shoot at the same time.
 * Skeletons walk away from players when too close to the player and towards the player when too far. They will also sprint towards you when very far away.
 * Skeletons now have new idle sounds.
 * Now can spawn due to a "skeleton trap" horse.


 * Lightning
 * Natural lightning strikes may spawn "skeleton trap" skeletal horses.
 * Chance depends on regional difficulty: 3.75–7.5% chance on Easy, 7.5–20% chance on Normal, 11.25–33.75% chance on Hard.


 * Horses
 * Added "skeleton trap" horses. When a player approaches to within 10 blocks, the following will happen:
 * The  flag is cleared.
 * The horse will become skeletal if it isn't already.
 * The horse becomes tame.
 * The horse becomes fully grown (if a baby) and the breeding cooldown is reset.
 * Lightning strikes the horse.
 * A skeleton is spawned riding the horse.
 * If on peaceful, the Skeleton will not spawn, while the Horse does.
 * The skeleton has damage immunity for 3 seconds.
 * The skeleton will not despawn ( is set).
 * The skeleton will be wearing an iron helmet, unless it randomly spawned with some other headgear.
 * The skeleton's bow and helmet will be enchanted as if on an enchantment table at level 5–22. The level is higher depending on regional difficulty; on Easy it will always be a level-5 enchantment.
 * Three additional skeletal horses with riders will be spawned in the vicinity.
 * New NBT tags:
 * (byte): Indicates whether the horse is a skeleton trap (i.e. whether or not the horse will spawn 4 undead horsemen in its place when a player gets within 10 blocks of it)
 * (integer), incremented each tick when  is set to 1. The mob automatically despawns when it reaches 18000 (15 minutes). This will prevent the hostile horses from overflowing the world, similar to chicken jockeys.

 * Fire
 * Fire goes out less often in the rain than it did before.
 * The chance of going out each fire tick is reduced from 100% to 0–45%, depending on the  property.
