23w03a is the first snapshot for Java Edition 1.19.4, released on January 18, 2023,^[1] which adds the /ride command and new interaction methods in options screen, makes technical changes, and fixes bugs. This is the first snapshot released in 2023.

Game rule

• Added commandModificationBlockLimit, defaults to 32768.
  • Controls the maximum number of blocks changed in one execution of /clone, /fill, and /fillbiome commands.

/ride

• A new command to allow entities to start or stop riding other entities, syntaxes:
  • /ride <target> mount <vehicle>: makes a single target mount a single vehicle, fails if:
    • vehicle is a player;
    • target is already riding a vehicle;
    • target and vehicle are the same entity;
    • vehicle is already a passenger (direct or indirect) of target.
  • /ride <target> dismount: dismounts target from any vehicle it is riding, fails if target is not riding anything.

Title screen

• Added an accessibility onboarding screen for players launching the game for the first time.
• Added arrow key navigation.
  • Menu screens can now be navigated by using the arrow keys.
  • When navigating with arrow keys, sliders need to be activated by pressing or to start changing the value.

Options

• Added a new "Notification Display Time" accessibility option, to change how long the notifications such as unlocked recipes, advancements, subtitles and selected item names are visible.

Protocol

• Added a network protocol feature for forcing bundle of packets to be processed within same client tick.
  • Added new delimiter packet to clientbound game protocol.
  • All packets between two delimiters are guaranteed to be processed within same tick.
  • For security reasons this feature is not supported in serverbound direction.

Tag

• Added following biome tags:
  • #increased_fire_burnout: contains bamboo_jungle, mushroom_fields, mangrove_swamp, snowy_slopes, frozen_peaks, jagged_peaks, swamp, and jungle.
    • Fire burns out faster in these defined biomes.
  • #snow_golem_melts: contains badlands, basalt_deltas, crimson_forest, desert, eroded_badlands, nether_wastes, savanna, savanna_plateau, soul_sand_valley, warped_forest, windswept_savanna, and wooded_badlands.
    • Snow golems melt in these defined biomes.
  • #spawns_snow_foxes: contains snowy_plains, ice_spikes, frozen_ocean, snowy_taiga, frozen_river, snowy_beach, frozen_peaks, jagged_peaks, snowy_slopes, and grove.
    • Snow foxes spawn in these defined biomes.
  • #spawns_white_rabbits: contains snowy_plains, ice_spikes, frozen_ocean, snowy_taiga, frozen_river, snowy_beach, frozen_peaks, jagged_peaks, snowy_slopes, and grove.
    • White rabbits spawn in these defined biomes.

Donkeys, mules, skeleton horses, and zombie horses

Vexes

• Now use a separate charging animation when empty-handed.

Armor stand

• Now preserve custom names when placed and broken.

Minecart with hopper

• No longer have TransferCooldown data.

Chat component

• Added an optional fallback field to translate text components.
  • The new field is a string that is used in place of translation if it is missing.
  • If fallback is missing, the old behavior (i.e. using the key itself as the translation) is preserved.
• Out-of-bound arguments in translate formats are no longer silently ignored.

/clone

• Now supports specifying the source and target dimensions, new syntax:
  • /clone [from <sourceDimension>] <begin> <end> [to <targetDimension>] <destination> ...
    • sourceDimension: ID of dimension to clone from.
    • targetDimension: ID of dimension to clone to.

/data

• New source string available, to read a value as text and resulting in a string value, syntax:
  • ... (insert <index>|prepend|append|set|merge) string (block <sourcePos>|entity <source>|storage <source>) [<sourcePath>] [<start>] [<end>]
    • start: index of first character to include at the start of the string.
    • end: index of the first character to exclude at the end of the string.

/execute

• On (if|unless), new conditions available:
  • ... loaded <pos>: checks if the position given is fully loaded (in regard to both blocks and entities).
    • pos: block position to check.
  • ... dimension <dimension>: checks if the execution is in a matching dimension.
    • dimension: a dimension ID.
• New sub-command: on, for selecting entities based on relation to the current executing entity, syntax:
  • ... on (attacker|controller|leasher|owner|passengers|target|vehicle) -> execute
    • attacker: last entity that damaged the executing entity in the previous 5 seconds.
    • controller: entity that is controlling the executing entity (for example: first passenger in a boat).
    • leasher: entity leading the executing entity with a leash (might be a leash knot in case of being attached to a fence).
    • owner: owner of the executing entity, if it is a tameable animal (like cats, wolves or parrots).
    • passengers: all entities directly riding the executing entity (no sub-passengers).
    • target: attack target for the executing entity.
    • vehicle: entity that the executing entity is riding.
  • If the relation is not applicable to the executing entity or there are no entities matching it, selector returns zero elements.

/title

• All time arguments to /title times are now time durations and work with t, s, and d suffixes.

/weather

• The duration of the weather change now matches the game's regular weather cycle if not specified.
• The duration parameter is now a time duration in ticks and works with t, s, and d suffixes.
  • To retain existing functionality, you need to add an s suffix to pre-existing commands.

Data pack

• The pack format version is now 11.

Custom biome

• Removed precipitation precipitation type field.
• Added has_precipitation boolean field.

Options

• Auto-jump is now off by default.

These additions and changes only take effect when the 1.20 experimental data pack is enabled.
