1.11.1 was an minor update for Minecraft (Java Edition) released on December 20, 2016.^[1] It is not compatible with 1.11 servers. This update added iron nuggets, which can be smelted from iron tools and weapons; the Sweeping Edge enchantment; and fireworks can now boost flying players.

Additions

Items

Iron Nuggets

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

Gameplay

Enchantments

• Added Sweeping Edge.
  • Can be applied to a sword to increase the damage of the sweep attack.
    • The damage dealt will be multiplied by 1¹⁄₂ on Level I, 1²⁄₃ on Level II, and 1³⁄₄ on Level III.

Changes

Blocks

Furnaces

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

Non-mob entities

Fireworks

• While flying using elytra, using a firework will give the player a boost for a certain amount of time. This will emit particles when in use.
  • Fireworks stay at the player's 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 5 without armor on, and with full diamond armor, it equates to about 1.
  • Death message is "[player] went off with a bang".

Gameplay

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 plus sign (+) underneath the crosshair.

Enchantments

• Mending is no longer compatible with Infinity on bows when trying to apply them with an anvil or when using the /enchant command.
  • Old bows with both enchantments applied will still keep their enchantments and remain working as they used to.
• Anvils will no longer apply enchanted books to items, if the result has no effect
  • This can occur if all enchantments on the book are incompatible with existing enchantments on the item.
  • This can also occur if the enchanted book has no enchantments.

General

Totem of Undying

• ID name changed from totem to totem_of_undying.

Statistics

• Removed the 'Junk Fished' and 'Treasure Fished' statistics

Pistons

• Added a new byte tag source for the piston_extension 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 Color to be used by the arrow entity, for displaying the custom potion color of a fired arrow item that had a CustomPotionColor tag.
