Experimental

These additions and changes are accessible by enabling the "Beta APIs", "Upcoming Creator Features", and "Render Dragon Features for Creators" experimental toggles.

Additions

Technical

API

Added Dimension.getGeneratedStructures(location: Vector3) which can be used to locate the Structures (Pillager Outpost, Mineshaft, etc.) of a given location.
Added worldAfterEvents.playerUseNameTag which fires when a Player uses a named NameTag Item on an Entity.
Added ControlScheme string enum.
Added method Player.setControlScheme(controlScheme?: string): void; to beta.
Added method Player.getControlScheme(): ControlScheme; to beta.

Blocks

Allow items referencing a pottable block in their minecraft:block_placer component to be pottable when replace_block_item is true.

Editor

Added an offset and alignment property to the summon tool so that creators can more easily position entities at specific locations.

Graphical

Deprecated point_lights/global.json in favor of a new file and schema, local_lighting/local_lighting.json. Creators can still make use of point_lights/global.json, but are encouraged to migrate to the new schema.
- Extended per-block local lighting information to include a light_type which can be either static_light or point_light.
  - A block will only be considered for point lighting if its light_type is set to point_light.
  - static_light is currently unused.
- The light_color property is now optional. If unprovided, the block will use a fallback light color instead.
- A sample local_lighting.json could look like this: format_version: 1.21.120, minecraft:local_light_settings: minecraft:torch: light_color: #EFE39D, light_type: point_light.

Molang

Added query.entity_biome_has_any_identifier, query.entity_biome_has_any_tags, and query.entity_biome_has_all_tags molang query functions to Upcoming Creator Features.

- entity_biome_has_any_identifier('namespace:biome_name') takes a list of biome identifiers and checks if any are the specified biome the entity is in.
- entity_biome_has_any_tags('my_tag_name') takes a list of biome tags and checks if the biome the entity is in matches any.
- entity_biome_has_all_tags('my_tag_name') takes a list of biome tags and checks if the biome the entity is in matches all.

Preview 1.21.120.25

Beta 1.21.120.25 (ChromeOS, Android) or Preview 1.21.120.25 (Windows, iOS, iPadOS, Xbox, PlayStation) is the sixth and final beta/Preview version for Bedrock Edition 1.21.120,^[6] released on October 7, 2025, which adds Realms Saves and fixes bugs.

Changes

General

Realms

The backups system has been replaced with a general "Saves" system. There are two types of Realms saves:
- Automatic saves are functionally the same as the previous backups system:
  - They are taken at the end of every Realms play session when the server shuts down, or every 30 minutes during a play session.
  - They are only retained for a limited time, according to the retention policy (which has not changed with this update).
  - They do not count towards the bank of cloud storage.
  - They are on by default and can't be turned off.
  - All previous Realms backups will be converted to automatic saves.
- Manual saves are created by the Realm owner and count towards a bank of storage that comes with the Realms subscription.
  - Manual saves are retained as long as the Realm exists. They are not automatically deleted by the retention policy, but Realm owners can delete manual saves if they want to free up storage space.
  - Realms Plus subscriptions come with 10GB of manual save storage and Realms Core subscriptions come with 5GB.
  - Automatic saves can be turned into manual saves by the Realm owner.
- Realms saves can be found in the Realms settings menu accessed via the "Edit Realm" button rather than the Realms world settings menu that backups used to show up in. While playing on the Realm, saves can also be found in the in-game settings menu for the Realm owner.
- Realms saves will also now list the world name and the packs that were applied at the time of the save.
