Java Edition 23w32a

23w32a is the second snapshot for Java Edition 1.20.2, released on August 9, 2023,^[1] which fixes bugs.

Loot table

• Added sequence loot function.
  • Contains 1 field:
    • functions: an array of sub-functions to run in sequence.
  • Can also be declared as an inline array without a type.
    • This matches the existing behavior where loot function JSON files can be declared as an array of composite functions.
• all_of predicates in loot tables can now be declared implicitly as an inline array without a type.
  • This similarly matches the existing behavior where loot predicate JSON files can be declared as an array of sub-predicates.

Sculk sensor and calibrated sculk sensor

• Vibrations no longer risk being lost on simulation distance limit.
• Can now detect the following events:
  • block_change, with frequency 11:
    • Carrots being eaten by rabbits.
    • Chiseled bookshelves receiving books from hoppers.
    • Sweet berries being eaten by foxes.
    • Turtle eggs cracking.
  • block_destroy, with frequency 12:
    • Fire being doused by water potion.
    • Turtle eggs hatching.
  • entity_place, with frequency 14:
    • Evokers evoking vexes or fangs.
  • item_interact_finish, with frequency 3:
    • Using bone meal.
  • unequip (new), with frequency 4:
    • Unequipping items.
• Camels eating cactus now emits an eat vibration with frequency 8, instead of entity_interact vibration with frequency 6.

Chat

• Clients no longer disconnect themselves when receiving an invalid chat message.
  • A placeholder message is instead shown in chat.

Chunk format

• Game no longer uses numeric values when storing mob effects to world.
  • For example, 4 becomes minecraft:mining_fatigue.
  • Changed following fields in mob effect instances:
    • Id (integer) -> id (string, resource location)
    • Ambient -> ambient
    • Amplifier -> amplifier
    • Duration -> duration
    • ShowParticles -> show_particles
    • ShowIcon -> show_icon
    • HiddenEffect -> hidden_effect
      • This field is a mob effect instance, so changes to the parent also applied here, recursively.
    • FactorCalculationData -> factor_calculation_data
• In NBT format for block entity type beacon:
  • Primary (integer) -> primary_effect (string, resource location)
  • Secondary (integer) -> secondary_effect (string, resource location)

Data pack

• The pack format version is now 17.

Debug screen

  • Renamed Effects to effects.
• In NBT format for entity type arrow:
  • Renamed CustomPotionEffects to custom_potion_effects.

player.dat format

• In NBT format for item type potion, lingering_potion, splash_potion, and tipped_arrow:
  • Renamed CustomPotionEffects to custom_potion_effects.

    • EffectId (integer) -> id (string, resource location)
    • EffectDuration -> duration

Protocol

• Optimized networking to improve the experience on low bandwidth connections.
  • Gameplay packets are now packed into bigger TCP-packets to reduce overhead from TCP-headers, significantly reducing network usage.

Resource pack

• The pack format version is now 17.
  • The text field background is now a nine-sliced sprite at widget/text_field and widget/text_field_highlighted.
  • The scroll bar in lists and text fields is now a nine-sliced sprite at widget/scroller.
