Stability and Performance

  • Fixed crash that could occur when logging Molang content

User Interface

  • Fixed caret movement acting twice and backspace deleting too many characters when using a physical keyboard on iOS

  • Improved how scrollable screen content is displayed in Ore UI menu screens on devices with notches, rounded corners or safe zones applied. Content now smoothly scrolls beneath the safe area instead of being cut off.

  • Furnace recipes will now unlock when you collect the corresponding material. The feature is available under "Experimental"

Technical Updates

Blocks

  • The pick-block action will now give the desired item in a flowerpot when the "minecraft:block_placer" component is defined with "replace_block_item" set to true (MCPE-234586)

  • Fix validation of large geometries that are scaled down with a transformation component (MCPE-236317)

AI Goals

  • Made the schema for minecraft:behavior.jump_around_target stricter when parsing, now will fail to load an entity json that has invalid data in versions 1.26.20 and newer. Float Range fields valid_distance_to_target and landing_distance_from_target now only accepts an object with min and max values. Other formats will fail to parse

  • Made the schema for minecraft:behavior.jump_to_block stricter when parsing, now will fail to load an entity json that has invalid data in versions 1.26.20 and newer. Float Range field cooldown_range now only accepts an object with min and max values. Other formats will fail to parse

  • Made the schema for minecraft:behavior.move_around_target stricter when parsing, now will fail to load an entity json that has invalid data in versions 1.26.20 and newer. Float Range field destination_position_range now only accepts an object with min and max values. Other formats will fail to parse

  • Made schemas for the following goals stricter when parsing and will fail to load an entity json that has invalid data in versions 1.26.20 and newer.

    • minecraft:behavior.find_cover
    • minecraft:behavior.find_mount
    • minecraft:behavior.find_underwater_treasure
    • minecraft:behavior.flee_sun

  • Made schemas for the following goals stricter when parsing and will fail to load an entity json that has invalid data in versions 1.26.20 and newer.

    • minecraft:behavior.float
    • minecraft:behavior.follow_owner
    • minecraft:behavior.follow_parent
    • minecraft:behavior.hold_ground

API

  • Added maximumRenderDistance property to DebugShape .

  • Added maximumRenderDistance property to PrimitiveShape .

  • The default render distance used by DebugShape and PrimitiveShape is now your client's render distance, instead of infinity. If you'd like to match the old behavior, you can set maximumRenderDistance to a very large number (Infinity isn't valid in scripting due to platform differences unfortunately).

  • Added InvalidType and UnsupportedValue to InvalidArgumentErrorType enum in @minecraft/common v1.3.0

DDUI

  • Made close buttons client authoritative so that forms close more quickly.

Editor

  • Toast notifications are grouped when multiple errors are triggered rapidly.

  • Disabled left mouse button paste in Paste Preview when Keyboard-only cursor mode is active

  • Added the Primitives tool to the Editor tool rail

  • Fixed Paste Preview appearing at an unpredictable position when entering Keys Only cursor mode from the dropdown, T key, or tool activation while Keys Only is already selected. The preview now appears at the block the player is looking at, or 32 blocks in front of the camera if no block is in view.

  • Implemented auto-save for structure detail setting and removed Save button and Save menu from structure detail pane

  • The Vibrant Visuals generate resource pack button now exports any edited configurations to a resource pack with a folder link provided

Entity Filters

  • Removed "has_equipment_block_tag" entity filter

    • We should not be looking at block tags on items for item behavior, and because of this the filter is being removed

General

  • Upgraded particles, trading, and cameras JSON resources to Cereal slice 1.26.10 and re-serialized to align with the updated schema.
  • Updated new features in structure pools to include data driven features.

Items

  • New 1.26.10 attachables now use a new 'controller.render.armor.v2' render_controller rather than using an updated 'controller.render.armor'. Fixes some creator content's custom armor not rendering properly

Network Protocol

  • Modified the binary format of PlayerEnchantOptionsPacket

User Interface

  • Fixed an issue causing the HUD to fail to load after disabling Screen Animations in-game, sometimes causing a soft-lock issue (MCPE-236881)
