Illager patrols
Resource packs
  • Added "Programmer Art – The classic look of Minecraft" to the resource pack menu.

Command format[edit]

  • General syntax: /loot <target> <source>.
  • Sources:
    • fish <loot table id> <fishing location> [tool <item>|mainhand|offhand]
      • Uses fishing context.
    • loot <loot table id>
      • Uses loot chest context (can be also used for advancement awards and cat gifts).
    • kill <entity selector>
      • Simulates entity drops.
    • mine <mining location> [tool <item>|mainhand|offhand]
      • Simulates block drops.
  • Targets:
    • spawn <position>
      • Drops in world.
    • replace
      • Works similar to /replaceitem. If count is missing, command will try to place all returned items. If count is higher than number of items, remaining slots will be cleared.
    • entity <entity selector> <start slot> [<count>]
      • Replaces a range of slots.
    • block <position> <start slot> [<count>]
      • Replaces range of slots.
    • give <player selector>
      • Inserts items into player's inventory (similar to /give).
    • insert <position>
      • Inserts items into container (similar to ⇧ Shift+left-click).



  • Rewrote the sign editing to be more intuitive.
  • New movable cursor for free text editing.
  • Selection support.
  • Copy and paste.

Command format[edit]

  • Renamed /drop to /loot and reworked the syntax to be easier to understand.
Advancement predicates
  • Entity predicate now accepts equipment field.
    • This predicate can contain up to six fields: head, chest, legs, feet, mainhand, offhand.
    • If this predicate is non-null, test will fail for entities that have no equipment (i.e. not mobs, players or armor stands).
