Technical Changes

  • The resource pack version is now 17
  • A bug involving hunger icons was fixed in the slicer tool released with last snapshot. Here is the new version
  • The data pack version is now 17
  • Optimized networking to improve the experience on low bandwidth connections

Resource Pack Version 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

Data Pack Version 17

  • Changed mob effect storage on items, entities and block entities

Mob effect storage changes

  • Game no longer uses numeric values when storing mob effects to world (so, for example, 4 becomes minecraft:mining_fatigue)
  • Various mob effect fields have been renamed for consistency with new structures

Mob Effect Instance

This structure is used in many places, so changes are described separately.

  • Id -> id, also changed from number to string id
  • Ambient -> ambient
  • Amplifier -> amplifier
  • Duration -> duration
  • ShowParticles -> show_particles
  • ShowIcon -> show_icon
  • HiddenEffect -> hidden_effect, also since it's mob effect instance, changes apply recursively
  • FactorCalculationData -> factor_calculation_data

Items

potion, lingering_potion, splash_potion, tipped_arrow
  • CustomPotionEffects -> custom_potion_effects, contents tranformed as a list of mob effect instances
suspicous_stew
  • Effects -> effects, for each entry:
    • EffectId -> id, also changed from number to string id
    • EffectDuration -> duration

Entities

mooshroom
  • Removed EffectId and EffectDuration
  • Added stew_effects with the same format as suspicious_stew.effects tag (i.e. list of effect id and duration)
area_effect_cloud
  • Effects -> effects, contents tranformed as a list of mob effect instances
arrow
  • CustomPotionEffects -> custom_potion_effects, contents tranformed as a list of mob effect instances
Players, Armor Stands and mobs
  • ActiveEffects -> active_effects, contents tranformed as a list of mob effect instances

Block Entities

beacon
  • Primary -> primary_effect, also changed from number to string id
  • Secondary -> secondary_effect, also changed from number to string id

Loot Tables

  • 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 with out 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

Network optimizations

  • Gameplay packets are now packed into bigger TCP-packets to reduce overhead from TCP-headers, significantly reducing network usage
  • Opening the debug screen with CTRL + F3 will now show charts for ping and received network traffic

Secure Chat

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