Bedrock Edition Preview 26.30.27

Beta 26.30.27 (ChromeOS, Android) or Preview 26.30.27 (Windows, iOS, iPadOS, Xbox, PlayStation) is the third beta/Preview for Bedrock Edition 26.30,^[1] released on May 3, 2026, for iOS and iPadOS, and on May 6, 2026, for all remaining devices, which moves the furnace recipe book out of experimental, updates sulfur springs, adds the magma block and slow bouncy sulfur cube archetypes, and fixes bugs.

Sulfur and cinnabar block sets

• Now have a blast resistance of 6 instead of 3.

Chiseled sulfur and chiseled cinnabar

• Can now be crafted from sulfur and cinnabar slabs.

Potent sulfur

• Now emits a vibration of frequency 10 when it starts erupting.
• Now emits a vibration of frequency 9 when it stops erupting.
• Updated noxious gas sounds.
• Geysers now have sounds.

Walls

• Leads can no longer be attached to sulfur and cinnabar walls.

Bee

• Can now pollinate, be aged, be bred, or be tempted with chorus flowers and spore blossoms.

Sulfur cube

• Sulfur cube spawn eggs now spawn a baby if used on a sulfur cube.
• Added unique hit and push sounds for the explosive ball archetype.
• Sulfur cubes can now be affected by Oozing.
• Added a new archetype for magma blocks.
  • When entities touch a magma block sulfur cube, they take fire damage.
  • This has unique sounds.
• Added a new slow bouncy archetype for stone-type blocks, which bounces slower with higher knockback resistance.
  • The regular archetype now only contains dirt-type blocks and concrete powder.
• Small sulfur cubes now have its own sound event for when landing after a jump.

Sulfur caves

• No longer generate with tuff and granite.
• Now generates less likely under oceans and mountains.
• Added a unique, green fog to sulfur caves. This is much denser volumetric fog with Vibrant Visuals.

Sulfur spring

• Updated the structures, with a bigger size, granite, tuff, and more block variations.
• Now generate only in flatter terrain.

Performance

• Improved character load time on the main menu.

Realms

• Added information surrounding resource packs download progress to join Realm progress message.
• "No Members Found" empty state no longer briefly shows up before loading members in the Realms Hub Members tab.

Server

• Dedicated servers now have the allowlist enabled by default in the server.properties, and will display a warning on server startup if the allowlist is enabled but contains no entries.

UI

• Implemented features from the furnace recipe book experiment into gameplay.
• Added a new color formatting code §w
   #8CB3FF party_blue_color, used to highlight party members nicknames in chat.
• Added Wishlist grid component to display Marketplace wishlist items with responsive column layout.

AI Goals

• Made the schemas for the following stricter when parsing, now will fail to load an entity json that has invalid data in versions 1.26.30 and newer:
  • minecraft:behavior.break_door
  • minecraft:behavior.door_interact
  • minecraft:behavior.hurt_by_target
  • minecraft:behavior.open_door
  • minecraft:behavior.owner_hurt_by_target
  • minecraft:behavior.owner_hurt_target
  • minecraft:behavior.random_look_around
    • Int Range field look_time now only accepts an object with min and max values. Other formats will fail to parse.
  • minecraft:behavior.random_look_around_and_sit
  • minecraft:behavior.wither_target_highest_damage

Blocks

• Released the culling_shape field in the minecraft:geometry component from behind the Voxel Shapes experiment. Non-unit-cube culling shapes for certain blocks (e.g. fences, bells, slabs) still require the experiment.
• Released the snow logging behavior for Block Precipitation Interaction component out of experimental.

DDUI

• Replaced Observable with ObservableString, ObservableNumber, ObservableUIRawMessage, and ObservableBoolean.
• Renamed DropdownItem to DropdownItemData.
• Changed some values of DataDrivenScreenClosedReason:
  • UserClose to ClientClosed.
  • ServerClose to ServerClosed.

Entity

• Released the execute_event_on_home_block entity event response out of experimental.

Events

• Added EntityStartSneakingAfterEvent and EntityStartSneakingAfterEventSignal to beta.

Features

• Added a new feature type height_difference_filter_feature.
  • This feature is meant to be used as a filter to filter away positions based on height differences close to the placed feature.
  • min_required_upward_height_diff - Specifies the minimum height difference required upwards.
  • min_required_downward_height_diff - Specifies the minimum height difference required downwards.
  • max_allowed_upward_height_diff - Specifies the maximum height difference allowed upwards.
  • max_allowed_downward_height_diff - Specifies the maximum height difference allowed downwards.
  • search_radius - Specifies the length in each cardinal direction the filter will check for blocks against the given differences.
  • places_feature - Specifies what feature should be placed when filter succeeds.
• Added an only_check_intersection_for_motion_blocking_blocks field to the block_intersection constraint of minecraft:structure_template_feature.
  • When true, only motion-blocking blocks within the structure are checked for intersections against the block_allowlist.
  • When false, all blocks in the structure except empty ones are checked for intersections, including air.
  • Defaults to true, preserving existing behavior.
  • Motion-blocking blocks are full blocks that block motion.
• Added the ground_level field to minecraft:structure_template_feature.
  • Specifies which Y coordinate of the structure is considered its ground level.
  • Used as a vertical offset during placement and determines which layer of the structure is checked by the leveled and grounded constraints.
  • All non-air blocks at this level define positions where the leveled and grounded constraints are checked.
  • If the value exceeds the structure's height, it is clamped to the maximum valid value and a content warning is emitted.
  • Defaults to 0.
• Added a new leveled option to the constraints field of minecraft:structure_template_feature.
  • When specified, ensures the structure's ground level is placed on mostly flat terrain.
  • Includes a max_steepness field that defines the maximum allowed height difference between the placement position and terrain samples taken at the structure's ground level.
    • A valid terrain sample consists of a solid block with a non-solid block above it.
    • Defaults to 2.

Scripting

• Released the isSnowLoggable method in ScriptBlockPrecipitationComponent from beta to 2.8.0.

These additions and changes are accessible by enabling the "Beta APIs", "Upcoming Creator Features", "Experimental Custom Projectile Features", and "Experimental Voxel Shape Features" experimental toggles.

API

• Added the new shape classes to @minecraft/debug-utilities library:
  • DebugCone
  • DebugCylinder
  • DebugPyramid
  • DebugEllipsoid

Blocks

• Added the lava_flammable field to the minecraft:flammable component under Upcoming Creator Features.
  • Supported values are always and never.
  • When set to always, the block is considered when lava attempts to spread fire after adjacent block updates, while still respecting normal fire placement rules.
  • When set to never, the block is excluded from that check.

General

• Added the owner_launch_immunity_ticks field to the projectile component.

Voxel Shapes

• Added occlusion voxel shapes for wall-mounted skull blocks when the Voxel Shapes experiment is enabled.
  • These shapes improve face culling so that hidden faces of custom blocks are correctly removed when a skull block is attached:
    • Wall-mounted skull shapes (6 blocks): Creeper Head, Dragon Head, Player Head, Skeleton Skull, Wither Skeleton Skull, Zombie Head
    • Wall-mounted Piglin shape (1 block): Piglin Head
