Minecraft Java Edition - 26.3 Release Candidate 1

Word around the campfire is the new forest biome is out in testing! But if nobody's been to the dappled forest before, who built the abandoned camp? And what loot did they leave among the poplar trees and red shrubs? Scout out the place and set up shelter using the new wood set and other features from our next game drop. The expedition into wilderness starts now in testing!

Happy mining!

Changes to give

  • When the amount of items passed to the give command is above limit, the command will now signal an error instead of just printing an error message and returning 0

Changes to tellraw

  • The nbt component in a raw chat message will only be resolved up to 64k times

Changes to tick

  • The following subcommands will now signal an error instead of just printing an error message and returning 0:

Changes to team

  • The result of team join and team leave subcommands now reflects the exact count of entities that have joined or left (i.e. excluding entities for which teams have not changed)

Changes to item

    • It will be evaluated with the minecraft:command_slot_source loot type
    • Can be a slot source in either inline or reference form
    • Can be a slot source targeting multiple slots
    • The replace sub-command has new semantics:
      • One by one in the order they are provided by the slot source, the contents of each destination slot are replaced with the corresponding source item
      • When there are more destination slots than there are source items, the remaining slots are ignored
        • Example: replace [12345] with (ABC) -> [ABC45]
      • When there are fewer destination slots than there are source items, the remaining items are ignored
        • Example: replace [123] with (ABCDE) -> [ABC]
    • String notation slot ranges in the form <slot_type> or <slot_type>.<slot_number> are still permitted
      • Can be a single slot, such as armor.chest
      • Can be multiple slots, such as container.*
      • Acts as shorthand for a minecraft:slot_range slot source using that slot range
        • Example: hotbar.4 is the same as {type:"minecraft:slot_range",slots:"hotbar.4"}
  • The entity argument in the from entity item source can now be a selector targeting multiple entities
    • When more than a single entity is targeted, the slots sourced from each are concatenated
  • Added new fill and override sub-commands, each with syntax identical to /item replace
    • /item fill
      • Fills each destination slot with a source item
      • When there are more destination slots than there are source items, the items repeat until every slot is filled
        • Example: fill [12345] with (ABC) -> [ABCAB]
    • /item override
      • Overrides the contents of each destination slot with the corresponding source item
      • When there are more destination slots than there are source items, the remaining slots are cleared
        • Example: override [12345] with (ABC) -> [ABC__] (where _ represents an empty slot)

Changes to execute

  • Added new slots condition sub-command
    • Counts the number of slots from the slot source that are present on the targeted block or entity
    • The slot source will be evaluated with the minecraft:command_slot_source loot type
    • Syntax:
      • /execute if|unless slots block <pos> <slot source>
      • /execute if|unless slots entity <targets> <slot source>
  • The items condition sub-command now takes a slot source as argument instead of a slot
    • The slot source will be evaluated with the minecraft:command_slot_source loot type
    • Syntax:
      • /execute if|unless items block <pos> <slot source> <item predicate>
      • /execute if|unless items entity <targets> <slot source> <item predicate>
