Bedrock Edition Preview 26.40.27

Beta 26.40.27 (ChromeOS, Android), Preview 26.40.27 (Windows, iOS, iPadOS, Xbox), or Preview 26.40.29 (PlayStation) is the fourth beta/Preview for Bedrock Edition 26.40, released on June 21, 2026, for iOS and iPadOS, on June 23, 2026, for most other devices, and on June 26, 2026, for PlayStation,^[1] which adds experimental features for the third drop of 2026 and fixes bugs.

Arrow

• Arrows fired by mobs with a 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.

Sulfur cube

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

Player

• Players can no longer get soft-locked when standing inside a sulfur cube's or a 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.

Realms

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

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

• Added new social drawer infrastructure with performance fixes.

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:
  • minecraft:jump.dynamic
  • minecraft:jump.static

API

• Renamed Dimension.findClosestBiome to Dimension.calculateClosestBiomeFromSeed and released from beta to scripts version 2.9.0.
• Released BiomeSearchOptions from beta to scripts version 2.9.0.

Block components

• Vanilla blocks defined with shapes in the shapes/ folder now use voxel-shape based culling without requiring the Voxel Shapes experiment.
  • This allows custom blocks using voxel-shapes to attempt to cull against any vanilla block with a voxel-shape.
• Fence connection changes now send server-side block updates to adjacent blocks. Older worlds keep legacy behavior for compatibility.
• Vanilla stairs 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.
  • Stair corner-state changes now trigger neighboring blocks to update for parity with Java Edition. Older worlds keep legacy behavior for compatibility.

Commands

• Using player names as a target for commands (i.e. /tell) for non-operator players is now allowed.

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 impact_damage on_hit subcomponent of minecraft:projectile:
  • Added a ceil_pre_critical_damage boolean field that rounds the projectile's damage up to the next integer before the critical hit multiplier is applied.
  • power_multiplier is now applied regardless of the difficulty_randomization 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 2 to 0 so that prior content remains unchanged when neither field is specified.
  • Replaced the semi_random_diff_damage boolean field with difficulty_randomization, which controls how the world difficulty contributes to the final damage:
    • none: difficulty is ignored (default).
    • additive: a difficulty-driven term is added to the base damage (matches the previous behavior when semi_random_diff_damage was true).
    • multiplicative: a difficulty-driven term is added to power_multiplier before it scales by the projectile's velocity.
• Added the minecraft:not_pickable_from_inside 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.

These additions and changes are accessible by enabling the "Beta APIs", "Upcoming Creator Features", and new "Drop 3 of 2026" experimental toggles.

Poplar sapling

• A new sapling which grows into any one of red, orange, or yellow poplar trees.

Dappled forest

• An autumn-themed forest biome which can be found near cold biomes that consists of poplar trees, red shrubs, leaf litter, brown mushrooms, shelf mushrooms, and rarely spruce trees.
  • Poplar trees and fallen poplar trees generate here. Fallen poplar trees generate more frequently than other trees.
  • Shelf mushrooms can be found here, placed on poplar trees and fallen poplar trees.
• The following passive and neutral mobs spawn in dappled forests, using their cold variants where applicable:
  • Chicken
  • Cow
  • Fox
  • Pig
  • Rabbit
  • Sheep

Poplar tree

• A tree that generates in dappled forests.

• Fallen poplar trees have shelf mushrooms on them.

Abandoned camp

• A structure that generates in the following biomes:
  • Meadow
  • Cherry Grove

  • Birch Forest
  • Old Growth Birch Forest
  • Flower Forest
  • Windswept Forest
  • Dappled Forest

• Chests and barrels can be found around the structure with loot.

API

• Added the SoundDefinition class to beta with read-only soundEventId and durationInfo properties.
• Added the SoundDefinitionDurationInfo interface to beta with a duration property.
• Added the SoundDefinitionFilter interface to beta with optional minDuration and maxDuration properties.
• Added the SoundDefinitionRegistry class to beta with a getDefinitions method that returns the loaded sound definitions, optionally narrowed by a filter.
• Added the World.soundDefinitionRegistry property to beta that provides read-only access to the sound definitions loaded for the world.
• Player.playSound now accepts a SoundDefinition in addition to a sound id string in beta.
• The minecraft:server_sound_definitions payload in sounds/sound_definitions.json 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 minecraft:server_sound_definitions 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.
• Added new beta interface SoundDefinitionMusicInfo with optional genres, moods, artist, and title properties describing the music content of a sound definition.
• Added new optional beta property SoundDefinition.musicInfo exposing the music metadata declared on a server sound definition.
• Added new optional beta property SoundDefinition.tags exposing the arbitrary tag metadata declared on a server sound definition.
• Added new optional beta properties on SoundDefinitionFilter 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 y_rotation_offset when using the minecraft:sixteen_way_rotation placement direction block trait.
• Added horizontal direction support for the minecraft:multi_block trait.
  • These new directions north, south, west, and east still require Upcoming Creator Features experiment to be enabled.
  • When placing horizontal multi-blocks, if one or more parts go into an unloaded LevelChunk, then the placement of all parts is delayed until both LevelChunks 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, then rotating the structure, the block parts will only rotate properly if the multi-block is also defined with the minecraft:placement_direction trait enabling the minecraft:cardinal_direction state. Otherwise, the multi-block parts will not respect the structures rotation.

DDUI

• Added image method onto CustomForm in @minecraft/server-ui to allow showing images on CustomForms.
