Biome Components

The minecraft:noise_gradient surface builder type has been updated. The API is the same as before, but the noise ranges provided are now clamped to the range [-1, 1] instead of [0, 1]

Blocks

The "lava_flammable" field of the "minecraft:flammable" component is now usable without the Experimental Upcoming Creator Features
Fixed block traits not respecting experimental requirements for format_version >= 1.26.20
Blocks with a custom beforeOnPlayerPlace scripting event placed by an item with a minecraft:block_placer component no longer desyncs upon placement (MCPE-238017)

Components

Added field 'stop_if_holding_item' to "minecraft:behavior.pickup_items"

- If true, the mob will not pick up another item if the item's preferred slot matches

Entity Components

Added the field extra_knockback_approach to minecraft:apply_knockback_rules preset settings for handling extra knockback from enchantments, sprinting and swimming
- reapply_default preserves the current behaviour where knockback is reapplied with the new power and a default preset
- multiply instead combines it into the original knockback calculation by multiplying the power value in the preset provided by minecraft:apply_knockback_rules
Made several changes to minecraft:pushable_by_entity presets:
- The min_distance field now controls the minimum range at which push interactions can occur for all push_mode values
  - Distance is measured as the horizontal distance between the centers of the two entities
- Renamed the kick_distance_threshold field to max_distance, which now controls the maximum range at which push interactions can occur for all push_mode values
  - Distance is measured as the horizontal distance between the center of the pushed entity and the edge of the pushing entity's collision box
- Added a play_sound field to control whether the pushed_by_player sound is played
- Added a new none value to the push_mode field, which disables pushing behavior entirely

Items

Items with both a "minecraft:use_modifiers" and a "minecraft:shooter" component with no available ammo will no longer draw with "start_using" set to "if_first" on the "minecraft:use_modifiers" component (MCPE-228331)

Renderer

Entity held_item_scale now accepts a Molang expression for state-driven scaling, and consistently applies to the main hand only in both first- and third-person

Stability and Performance

When leaving the game in split screen the ecomode system could receive a callback after the client had been removed causing a crash

User Interface

Fixed a bug where the coin icon may not appear on certain Marketplace offers

World Generation

Bedrock floor and ceiling will be placed regardless of "minecraft:surface_builder" and "minecraft:subsurface_builder" presence in the biome.json file

Experimental Technical Updates

API

Added EntityFogComponentError to @minecraft/server (beta)

Blocks

Added the minecraft:instrument_sound block component behind the Upcoming Creator Features experiment
- it can be used to assign an instrument to "up" and "down" faces of a block and it's permutations
  - all current instruments can be used to define a sound
  - newly added "note.none" can be used to specify no sound for a face
  - if a face is not defined it will use its default value; "up": "note.harp" and "down": "note.none"
  - at least one face must be defined for the component to be valid Example:

{
	"format_version": "1.26.20",
	"minecraft:block": {
		"description": {
			"identifier": "test:test_block"
		},
		"components": {
			"minecraft:instrument_sound": {
				"up": "note.bit",
                		"down": "note.bell"
			}
		}
	}
}
