Java Edition 15w41a

15w41a is the thirty-first snapshot released for 1.9.

This version has been removed from the launcher for quite a bit, then it was added back in September 2018.

Additions

 * Elytra
 * They function according to hang glider aerodynamics.
 * You don't receive fall damage if you fall from a small height while flying slowly (not nose-diving).
 * You still receive fall damage if you nose-dive directly into the ground.
 * Have to be equipped in the “chestplate” slot in order to work.
 * Have 431 uses and can be repaired on an anvil using leather.
 * When the durability reaches 1/432, will not break or take damage anymore. Instead the elytra will stop working and the texture changes to broken looking elytra.
 * Can be given the Unbreaking enchantment using an anvil or commands.
 * Legs will make a “walking movement” animation when you are stalling in the air.
 * Found on End Ships within an item frame, replacing the beacon/Searge's book
 * Wings fold while not gliding
 * Cape not displayed while wearing
 * Takes damage at a rate of 1/s
 * Similar to the Wing Cap item from Super Mario 64.
 * NBT Tags
 * All entities
 * (list): Replaces the original "Riding" compound tag. It has the ability to specify multiple passengers at equal depths, unlike "Riding". Instead of the deepest-nested "Riding" entity being the bottom-most in the stack of riding entities, the entity at the root of the data is at the bottom of the stack. For example, the armor stand in the following command is at the bottom of the stack while the cow and pig are at the same depth:
 * (compound): The "Riding" tag has been removed in favor of the new "Passengers" tag.
 * Players
 * With the introduction of the "Passengers" tag, this new compound holds a copy of the entity the player is currently riding. "AttachLeast" and "AttachMost" are the UUIDLeast and UUIDMost of that entity, while "Entity" holds the actual data.
 * Boats
 * (string): Determines the wood material of the boat that is displayed. Values are: oak, spruce, birch, jungle, acacia, dark_oak.

 * Crafting recipe now includes a wooden shovel for the oars.
 * Now require oar movement to move, using the and  keys – these controls were changed in a later snapshot, 16w04a.
 * The key will paddle the left oar, turning the boat to the right – and vice-versa.
 * Holding both and  will paddle both oars, propelling the player forward. Rapidly pressing  and  in alternation will make the boat travel even faster
