Bedrock Edition Preview 26.20.26

Beta 26.20.26 (ChromeOS, Android) or Preview 26.20.26 (Windows, iOS, iPadOS, Xbox, PlayStation) is the fifth beta/Preview for Bedrock Edition 26.20, released on April 8, 2026,^[1] which fixes bugs, and adds custom dimensions to the Beta APIs experiment.

Realms

• Added the Admin log feature to the Realms Hub.
  • Logs changes performed by Realm administrators, such as settings changes, add-ons, and world management.

Accounts

• Added platform subscription checks as part of multiplayer allowance check and return new platform-subscription-specific permission deny reasons if the check failed.

AI Goals

• Made the 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.go_and_give_items_to_noteblock
  • minecraft:behavior.go_and_give_items_to_owner
  • minecraft:behavior.go_home
  • minecraft:behavior.random_hover
  • minecraft:behavior.random_sitting
  • minecraft:behavior.random_stroll
• The hover_height field in minecraft:behavior.random_hover now only accepts an object with min and max values.

Block components

• Released the component minecraft:chest_obstruction from experimental for block format versions 1.26.20 or higher.

Blocks

• Added content warning for component minecraft:item_visual trying to use texture variations.
  • Variation textures are not supported for this component.
• The minecraft:selection_box component will correctly give an error again when the y is over the 16 limit.

Entity components

• The component minecraft:apply_knockback_rules now takes an array of presets.
  • presets is an array of elements with the same parameters as minecraft:apply_knockback_rules had previously.
• The preset elements have the following new field:
  • filter is an actor filter with the default syntax.
• Added the filters parameter to minecraft:spawn_on_death.

These additions and changes are accessible by enabling the "Beta APIs", "Upcoming Creator Features", "Render Dragon Features for Creators", "Experimental Voxel Shape Features", and "Drop 2 of 2026" experimental toggles.

Sulfur cube

• When hit by a player, its knockback is now affected by the attacker's hit angle, position and damage.

API

• Changed the maximum length of the text param of setText on TextPrimitive, to be 128 lines and 128 characters per line.
• Class DimensionRegistry:
  • Added the method registerCustomDimension to allow registrations of new custom dimensions in beta.
• Startup event:
  • Added the ability to register custom dimensions during the before startup event.

DDUI

• Added support for multiline texts for MessageBox.body, CustomForm.label, and CustomForm.header using \n.

Entities

• Added a new entity_version description field to entity behavior definitions that enables per-entity versioning and upgrade handling.
  • The entity_version field is a JSON object containing an upgrades array, where each entry specifies an integer upgrade_to version and a name string referencing an upgrade handler defined in a new top-level upgrades section of the entity definition.
  • Upgrade versions must start at 1 and be contiguous. Gaps or duplicates are rejected with a content error.
  • Version 0 is reserved for entities that have no version set ("versionless"), which is the default for all existing entities.
  • When an entity is loaded with a version older than the current definition version, all upgrade handlers between the entity's saved version and the current version are executed sequentially
  • Newly spawned entities are set directly to the latest version without running any upgrade handlers.
  • Upgrade handlers reuse the existing event system but are defined in a separate upgrades section, keeping them distinct from regular events.
  • The entity's version is persisted and loaded/saved automatically.

Entity components

• The following fields have been added to the preset element exclusively in the beta version of minecraft:apply_knockback_rules:
  • scale_previous_velocity scales the previous velocity of the target when hit.
  • horizontal_hit_angle_scale scales the horizontal angle response of the target when hit based on the attacker's aim direction.
  • vertical_hit_angle_scale scales the vertical angle response of the target when hit based on the attacker's aim direction.
  • vertical_position_angle_scale scales the vertical angle response of the target when hit based on the attacker's relative feet position.
  • scale_with_damage enables scaling the magnitude of knocback based on the inverse square of the damage.

Graphical

• Added static light shading to weather.

Voxel Shapes

• Added non-unit-cube voxel shapes for 19 blocks when the Voxel Shapes experiment is enabled:
  • Cake shapes (1 block): 7 bite-counter shapes for each slice of cake.
    • Candle cake shape (17 blocks).
  • Composter shapes (1 block): 8 fill-level shapes for each stage of composting.

20 issues fixed

From released versions before 26.20

• MCPE-227535 – Armor swapping & interacting with jukebox or composter creates ghost item.
• MCPE-236601 – No sound when placing partial blocks in water.
• MCPE-236872 – "Joystick & tap to interact" and "D-Pad & tap to interact" control modes are missing the 'Delay Breaking Blocks (Creative Mode Only)' option in the new Settings UI.

From the 26.20 development versions

• MCPE-237071 – Custom multi-blocks using random offset component have outline and collision incorrectly offset.
• MCPE-237089 – Custom multi-blocks with no selection component do not have rendered outline.
• MCPE-237222 – Custom pottable blocks with item overrides have incorrect interaction behavior with filled flower pots.
• MCPE-237404 – Smelting damaged weapons, tools, and armor no longer gives nuggets.
• MCPE-237498 – Custom multi-blocks do not respect survivability rules.
• MCPE-237713 – Custom entity components locked behind runtime IDs.
• MCPE-237757 – Ravager Changes Break Redstone Machines Relying on Block Breaking

Other

• Fixed an issue in Realms Stories where the Members tab did not load in correctly.
• Fixed a bug where emojis were not rendering at the small text tooltip when selecting an item in the HUD's hotbar.
• Fixed content warning regarding texture variations for block components minecraft:item_visual and minecraft:embedded_visual.
• Fixed legacy tag: entries in block permutations being silently dropped when upgrading to format version 1.26.20, which could cause scripts relying on permutation-specific tags to fail.
• Fixed player friction not resetting for older content.
• Fixed a bug where in-flight http requests could freeze the game when the http client is destroyed in scripting.
• Fixed an issue that caused websockets to not complete their connection with the server.
• Fixing a bug with Debug Drawing and Primitive Shapes where they could get into a bad state when used with Simulated Players.
• Fixed minecraft:replaceable to work with all parts of a multi-block. The component can no longer be defined in the permutations array, only allowed in the base components object.
