Changes

• Changes to vibration mechanic

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
