Anvil

• Used for repairing, merging & naming items.
  • Three different damage states: "Anvil", "Slightly Damaged Anvil", and "Very Damaged Anvil".
  • Anvils cannot only rename tools and armor, but any item.
    • Renamed placeable items don't retain their name if placed.
  • Anvils can merge enchantments.
    • Items with two different enchantments give an item with both.
    • Items with the same enchantment increase the level of the enchantment if they have the same level or take only the highest if they don't.
    • Some enchantments can be lost during the merging because of incompatibility (ex: Sharpness I + Smite I).
      • The first item seems to have the priority (the lost enchantments are on the second item).
  • Anvils can also be dropped in a similar manner to sand, gravel, and dragon eggs.
    • When landing on a mob, the anvil deals damage relative to the distance it fell.

Creepers

• Now can have custom explosion radius and fuse timer using edited mob spawners and NBT data (ExplosionRadius & Fuse).

Beacons

• Potion-like effects given by the beacon now use semi-transparent particles, to be less intrusive.
• Normal potions remain unchanged.

General

• No longer forget that they are aggressive against a player in Creative mode after a few seconds.

Experience

• Can now be obtained by breeding animals.
• Level-up sound now only plays every 5 levels.
  • Sound has been tweaked.

Debug screen

•  +  now shows tool and armor durability on damaged items – on maps it shows the zoom level.
• Now shows which cardinal direction the player is facing on the "f" value.
• The pie chart on the debug overlay is now shown when opening it using  +  instead of vice versa.

Settings menu

• Renamed "Chat Settings" to "Multiplayer Settings".
  • Contains the old chat settings menu.
  • Option for cape-owners to hide their capes in game.

5 bugs fixed

• When placing the anvil in mid-air in a certain orientation the entity will be sideways until it lands.
• Breaking the block under any anvil resets it to a regular anvil.
• When using the /kill command, an error appears. When holding a block, it gives the normal message, but player doesn't die.
• When in a multiplayer server and trying to rename an item, the client crashes if an entire name is erased.
• Using Fortune ≥ IV (normally impossible to obtain) on gravel causes a game crash.
