Java Edition 16w50a

16w50a is the snapshot released for 1.11.1, and the final snapshot released in 2016.

Additions

 * Iron Nuggets
 * Can be crafted from iron ingots, but are also received from smelting iron tools and armor.
 * Can be crafted into iron ingots.


 * Sweeping Edge Enchantment
 * Can be applied to a sword to increase the damage of the sweep attack.
 * Level 3 will make the sweep attack damage as potent as the regular attack damage.

Changes

 * Attack indicator
 * When in crosshair mode, the weapon is fully cooled, and a mob or entity is in range of attack, the attack indicator will be visible and will include a small exclamation point underneath the crosshair (later changed to a plus-sign (+) in the final release )


 * Enchantments
 * Mending is no longer compatible with Infinity on bows when trying to apply it in survival or when using the command.
 * In this snapshot however, you can still add mending to an infinity bow, but not vice versa.
 * You can also put Infinity on a Mending enchantment book, but not vice versa.
 * Old bows with both enchantments applied, will still keep their enchantments and remain working as they used to.


 * Fireworks
 * While flying using elytra, using a firework will give the player a boost for a certain amount of time. This will emit particle when in use.
 * Fireworks stay at the players location until they disappear or explode.
 * Longer flight duration on the rocket will make the boost last longer. You can increase the flight duration of a firework by crafting it with gunpowder in the other slots.
 * Fireworks with an explosion will deal damage at the end of their flight.
 * The right click on a block action for the fireworks is prioritized over the right click ability in midair. This simply means that when you look at a block while flying and right click, the rocket will shoot regularly, instead of being used as a boost.
 * Firework explosions now hurt surrounding mobs and players.
 * The damage radius of the explosion is about 2-3 blocks and is the same for any shape (large ball, creeper, burst, etc.) and the damage decreases with the distance to the explosion.
 * The damage amount at close range is about without armor on, and with full diamond armor, it equates to about.
 * Death message is "[player] went off with a bang".


 * Furnaces
 * Iron and golden tools and armor can be smelted into nuggets. Iron and golden horse armor can also be smelted.
 * Yield 1 iron or golden nugget per item respectively.


 * Totem of Undying
 * ID name changed from  to


 * Statistics
 * Removed the 'Junk Fished' and 'Treasure Fished' statistics


 * Pistons
 * Added a new byte tag  for the   block entity, which is true if the block represents the piston head itself, and false if it represents a block being pushed.


 * Arrows
 * Added a new integer tag  to be used by the   entity, for displaying the custom potion color of a fired arrow item that had a   tag.

This snapshot was accidentally released under "snapshot 1.11.1"; this was later fixed. The jars for the client and server are still available from Mojang's servers.
