e.g. tooltip_style='minecraft:special_sword'.

Predicates

Added a new field in the player sub-predicate, input, that can be used to detect which movement keys the player is pressing.
- If specified the predicate matches with the corresponding keybind that the player is pressing; it supports detecting the following input:
  - forward: boolean (optional).
  - backward: boolean (optional).
  - left: boolean (optional).
  - right: boolean (optional).
  - jump: boolean (optional).

Changes

This section is missing information about:

Does the tooltip background look any different in this snapshot compared to the last one? If so, can a visual comparison be added?
Someone mentioned the tooltip texture not being changeable to a developer on Twitter not long before this snapshot released. Can this post be found and linked here?.

Please expand the section to include this information. Further details may exist on the talk page.

Mobs

Squids

Squid spawn eggs now only spawn adult squids.
- There is a 5% chance of squids spawned in groups in the wild to be a baby.

General

When a mob converts from one type to another (e.g. piglin to zombified piglin), the health of the converted mob is set to the same percentage of max health as the original mob had before conversion.
The calculation for the duration of the effect from splash potions has been changed. Splash potions thrown at the player's feet now apply the effect for almost the same duration as when thrown at the head.^[2]

General

Data component format

minecraft:item_name
- This component is now always present on every item.

Data pack

The pack format version is now 52.

Models

All item models can now use the broken property in model overrides that was previously limited to just the elytra.
- This has a value of 1 if the item has 1 durability left, or 0 otherwise.
The appearance of equipment when equipped by players or certain mobs can now be customized by defining 'equipment models' in the resource pack.
- Equipment model definitions are loaded from assets/<namespace>/models/equipment/<path>.json.
  - These can then be referenced by the equippable component with a model id of namespace:path.
- The model definition is an object with fields: wolf_body, horse_body, llama_body, humanoid, humanoid_leggings, wings
  - All fields are optional, and can be used to specify a list of layers for the given model layer type.
  - Each field contains list of layer objects:
    - texture: namespaced texture location for this layer.
      - namespace:path resolves to assets/<namespace>/textures/entity/equipment/<layer_type>/<path>.png
    - dyeable: object with fields (optional), specifying how this layer behaves when dyed (in the dyeable item tag, and has dyed_color component)
      - color_when_undyed: RGB color int (optional)
      - If specified, this layer is tinted by the color contained in the dyed_color component.
        If the item is not dyeable or not dyed, it is tinted based on the color specified by color_when_undyed.
        
        If color_when_undyed is not specified and the item is not dyed, the layer is hidden.
    - use_player_texture: boolean (default: false), true if this layer texture should be overridden by a texture given by the player.
      - Only used for wings layers, which overrides with the player's custom elytra texture.

Resource pack

The pack format version is now 37.
The tooltip background and frame may now be customized by replacing sprites:
- tooltip/background: The background of the tooltip.
- tooltip/frame: The frame appearing around the tooltip.
- Items with a custom tooltip_style component uses sprites with IDs:
  - <namespace>:tooltip/<path>_background and <namespace>:tooltip/<path>_frame
The nine_slice GUI sprite scaling mode has a new optional boolean (true or false, yes or no) property: stretch_inner.
- If true, the inner parts of the texture (i.e. not the corners) are stretched instead of tiled.
- If not specified, defaults to false as before.

Textures

All equipment-related textures were moved to subfolders of the textures/entity/equipment directory.
- Player armor textures were moved to textures/entity/equipment/humanoid and textures/entity/equipment/humanoid_leggings
  - <material>_layer_1 textures were renamed to <material>, and moved into the humanoid subdirectory.
  - <material>_layer_2 textures were renamed to <material>, and moved into the humanoid_leggings subdirectory.
  - leather_layer_1_overlay and leather_layer_2_overlay textures were renamed to leather_overlay in their respective subdirectories.
- wolf_armor and wolf_armor_overlay textures have moved to textures/entity/equipment/wolf_body/ and were renamed to armadillo_scute and armadillo_scute_overlay respectively.
- turtle_layer_1 has been renamed to turtle_scute.
- Llama decor textures were moved to textures/entity/equipment/llama_body
- Horse armor textures were moved to textures/entity/equipment/horse_body
- The elytra texture has been moved to textures/entity/equipment/wings/elytra
Armor trim textures have also been moved to match the folder structure of the regular equipment textures.
- Textures in textures/trims/models/armor were divided between textures/trims/entity/humanoid and textures/trims/entity/humanoid_leggings
- For leggings textures, the _leggings suffix is dropped.

Trims

All equippable items with an equipment model defined support rendering trims, based on the trim component.
Trim textures are loaded from the appropriate folder in the textures/trims/entity directory.
- For example, armor with wolf_body layers fetch trims from textures/trims/entity/wolf_body

Experimental

Bundles

When a bundle is used in the hotbar, one group of items is emptied at a time instead of everything being emptied at once.
