Java Edition 23w32a

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

Additions

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.

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.

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

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)

Opening it with Ctrl + F3 now shows charts for ping and received network traffic.

In NBT format for entity type mooshroom:
- Removed EffectId and EffectDuration.
- Added stew_effects, with the same format as effects field in suspicious_stew item format.
In NBT format for entity type area_effect_cloud:
- Renamed Effects to effects.
In NBT format for entity type arrow:
- Renamed CustomPotionEffects to custom_potion_effects.
In NBT format for living entities (players, armor stands, and all mobs):
- Renamed ActiveEffects to active_effects.

Game events

In NBT format for item type potion, lingering_potion, splash_potion, and tipped_arrow:
- Renamed CustomPotionEffects to custom_potion_effects.
In NBT format for item type suspicious_stew:
- Renamed Effects to effects, also changed following fields in this field:
  - 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.

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.
