Minecraft:Bedrock Edition Preview 26.40.27

Beta 26.40.27 (ChromeOS, Android) or Preview 26.40.27 (Windows, iOS, iPadOS, Xbox, PlayStation) is the fourth beta/Preview for Minecraft:Bedrock Edition 26.40, released on June 23, 2026,<ref>Template:Cite</ref> which adds experimental features for the third drop of 2026 and fixes bugs.

Changes

Mobs

Minecraft:Sulfur cube

• High levels of the Minecraft:Strength effect now correctly increase the distance at which a sulfur cube with an absorbed block is knocked back.

Minecraft:Player

• Players can no longer get soft-locked when standing inside a sulfur cube's or a Minecraft:creaking's bounding box, as they are now able to interact with the entities and blocks around them through the mob.
  • Applies only when the entities are invulnerable.
  • Replaces the workaround where creakings would despawn after blocking a player for too long.

Items

Minecraft:Arrow

• Arrows fired by mobs with a Minecraft:crossbow now deal the same damage regardless of the shooting mobs.
• Arrows fired by players or other mobs with a crossbow are no longer affected by difficulty.

General

Minecraft:Realms

• Added a Delete button on the Subscriptions tab for expired Realms.
• Updated terms on Realms purchase screen.

Minecraft:Settings

• Added frame pacing for Xbox platforms in Preview, disabled by default.
• Updated old and retail world conversion flows in the Storage settings tab.

UI

• New social drawer infrastructure with performance fixes.

Technical

AI Components

• Made schemas for the following components stricter when parsing and will fail to load an entity json that has invalid data in versions 1.26.40 and newer.
  • Template:Cd
  • Template:Cd

Minecraft:API

• Renamed Template:Cd to Template:Cd and released from Template:Cd to scripts version Template:Cd
• Released Template:Cd from Template:Cd to scripts version Template:Cd

Minecraft:Block components

• Vanilla blocks defined with shapes in the shapes/ folder now use voxel-shape based culling without requiring the Voxel Shapes experiment. This will allow custom blocks using voxel-shapes to attempt to cull against any vanilla block with a voxel-shape.

Fences

• In 1.26.40+ worlds, fence connection changes now send server-side block updates to adjacent blocks. Older worlds keep legacy behavior for compatibility.

Stairs

• Vanilla stair blocks now expose a minecraft:corner block state (none, inner_left, inner_right, outer_left, outer_right) reflecting the corner shape formed with adjacent stairs.
• For new worlds (base game version 1.26.40 and later), stair corner-state changes now trigger neighbor block updates for parity with Java Edition; existing worlds keep the prior client-only update behavior.

Minecraft:Commands

• Using player name as target for commands (i.e. Template:Cmd) for non-operator players is now allowed.

DDUI

• Added image method onto Template:Cd in Template:Cd to allow showing images on Template:Cd.

Dedicated Server

• Added CLI options to run the dedicated server in pack optimization mode, allowing creators to optimize packs for testing and distribution inside and outside Marketplace.

Entity components

• Made the following changes to the Template:Cd Template:Cd subcomponent of Template:Cd:
  • Added a Template:Cd boolean field that rounds the projectile's damage up to the next integer before the critical hit multiplier is applied.
  • Template:Cd is now applied regardless of the Template:Cd mode, so it can be used on its own to scale damage by the projectile's velocity.
    • The resulting value is added to damage to define the projectile's base damage.
    • Its default value changed from Template:Cd to Template:Cd so that prior content remains unchanged when neither field is specified.
  • Replaced the Template:Cd boolean field with Template:Cd, which controls how the world difficulty contributes to the final damage:
    • Template:Cd: difficulty is ignored (default).
    • Template:Cd: a difficulty-driven term is added to the base damage (matches the previous behavior when Template:Cd was Template:Cd).
    • Template:Cd: a difficulty-driven term is added to Template:Cd before it scales by the projectile's velocity.
  • Content authored against earlier format versions is automatically upgraded when loaded in 1.26.40 or later to preserve existing behavior2.
• Added the Template:Cd entity component.
  • When set, the entity cannot be targeted by a cursor hit-test while the picker's point of view lies inside the entity's collision box.

Changes

Technical

Minecraft:API

• Added the Template:Cd class to beta with read-only Template:Cd and Template:Cd properties.
• Added the Template:Cd interface to beta with a Template:Cd property.
• Added the Template:Cd interface to beta with optional Template:Cd and Template:Cd properties.
• Added the Template:Cd class to beta with a Template:Cd method that returns the loaded sound definitions, optionally narrowed by a filter.
• Added the Template:Cd property to beta that provides read-only access to the sound definitions loaded for the world.
• Template:Cd now accepts a Template:Cd in addition to a sound id string in beta.
• Added the Template:Cd class to beta with read-only Template:Cd and Template:Cd properties.
• Added the Template:Cd interface to beta with a Template:Cd property.
• Added the Template:Cd interface to beta with optional Template:Cd and Template:Cd properties.
• Added the Template:Cd class to beta with a Template:Cd method that returns the loaded sound definitions, optionally narrowed by a filter.
• Added the Template:Cd property to beta that provides read-only access to the sound definitions loaded for the world.
• Template:Cd now accepts a Template:Cd in addition to a sound id string in beta.
• The Template:Cd payload in Template:Cd now accepts an optional music_info block on each definition with optional genres (array of strings), moods (array of strings), artist (string), and title (string) fields that describe the music content of the sound.
• The Template:Cd payload now accepts an optional tags map on each definition where each entry is a tag name mapped to either a single string value or an array of string values, letting behavior packs attach arbitrary metadata to a server sound definition.

<syntaxhighlight> "music_info": {

               "genres": ["electronic", "ambient"],
               "moods": ["calm"],
               "artist": "Some Artist",
               "title": "My Cool Song"
           },
           "tags": {
               "category": "background",
               "regions": ["overworld", "nether"]

}</syntaxhighlight>

• Added new beta Template:Cd with optional genres, moods, artist, and title properties describing the music content of a sound definition.
• Added new optional beta Template:Cd exposing the music metadata declared on a server sound definition.
• Added new optional beta Template:Cd exposing the arbitrary tag metadata declared on a server sound definition.
• Added new optional beta properties on Template:Cd for filtering by music metadata and tags: genres, moods, artists, titles, and tags. All comparisons are case-insensitive. An omitted field does not filter; a non-empty array matches when any provided value overlaps the definition's values.

Blocks

• Block dynamic properties are now bucketed by manifest-UUID rather than module-UUID.
• Added support for Template:Cd when using the minecraft:sixteen_way_rotation placement direction block trait.
• Added horizontal "Template:Cd" support for the Template:Cd trait.
  • These new directions "Template:Cd", "Template:Cd", "Template:Cd", "Template:Cd" still require Upcoming Creator Features experiment to be enabled.
  • When placing horizontal multi-blocks if one or more parts go into an unloaded Template:Cd then the placement of all parts is delayed until both Template:Cd are loaded, delayed placement actions are persistent and saved to Level storage until they are executed.
  • If placing the horizontal multi-block in a structure template, and then rotating the structure, the block parts will only rotate properly if the multi-block is also defined with the Template:Cd trait enabling the Template:Cd state, otherwise the multi-block parts will not respect the structures rotation.
