Additions[edit]

Command format[edit]

/teleport.
  • Added facing to the command.
    • /teleport [<targets>] (<location>|<destination>) facing (<facingEntity>|<facingLocation>).
    • Will rotate an entity to face either an entity or a location.
  • Added noon and midnight to /time set.

General[edit]

Data packs
  • Added set_name function to loot tables.
  • Functions tagged in minecraft:load will now run once after a (re)load.
  • Added the new block tag minecraft:anvil.
    • Contains minecraft:anvil, minecraft:chipped_anvil, and minecraft:damaged_anvil.
Death messages
  • Added a death message for when a mob or player causes another player to die in the void.
    • "Player didn't want to live in the same world as Player/Mob".

Changes[edit]

Command format[edit]

  • Changed all custom names (blocks, items, entities, block entities) to translatable text components.
    • Removed the LocName tag. Instead of LocName:"gui.toTitle", use Name:"{\"translate\":\"gui.toTitle\"}".
  • Thrower and Owner nbt keys of item entities are no longer strings but are instead compounds with two longs named L and M.
  • owner nbt keys of snowballs, eggs and ender pearls are no longer strings but are instead compounds with two longs named L and M.

General[edit]

Crashes
  • Crash reports now list what data packs are enabled.
Data generators
  • Now exposed, the player can get a dump of all blocks/items/commands/etc. from the game without opening it up.
