Minecraft Bedrock 1.21.80.21 beta and preview patch notes: Locator bar improvement, bug fixes, and more

Mojang has released a new beta and preview for Minecraft Bedrock Edition. While Java Edition is still busy fixing the last few bugs before the release of the spring drop, Bedrock Edition has already moved on to developing the second game drop of 2025.

Minecraft Bedrock 1.21.80.21 beta and preview improve the locator bar, a feature announced for the second game drop. Aside from that, Mojang has reverted a fix from previous beta/preview that despawned existing glitched invincible mobs from worlds. Mojang has also removed access to VR gameplay, as previously announced for updates released after March 2025.

Minecraft Bedrock 1.21.80.21 also includes a few UI improvements and mostly bug fixes. Without further ado, let's go through the patch notes for the latest Minecraft Bedrock 1.21.80.21 beta and preview.

Minecraft Bedrock 1.21.80.21 patch notes

Experimental Features

User Interface

• Player Dots on the Locator Bar now show correctly regardless of Simulation Distance

Features and Bug Fixes

• Due to unexpected codebase issues identified during Preview, we have reverted a recent change that caused "invincible pet" mobs to despawn (MCPE-188731)
• Mobs in worlds opened during Preview may have despawned, but players updating to the upcoming 1.21.70 release should be unaffected
• As always, remember to keep backups of your worlds before major updates
• Removed access to Virtual and Mixed Reality gameplay

Blocks

• Fix ambient occlusion issue for non 1x1x1 blocks
• When a block around any of these smaller non 1x1x1 blocks is broken, the AO computation is correctly applied to the face in the direction of that broken block. Previously the wrong face could be seen getting lightened/darkened.
• A list of blocks affected: stairs, walls, gates, buttons, cakes, plates, fences, anvil, grindstone, hopper, bell, lectern, eggs, brewing stand

Gameplay

• Fixed server client desync issue during portal travel on Realms (MCPE-188731)
• Added 'music_definition' field to 'minecraft:biome_music' component in client_biome json files to control the music played in the biome. The default music will be determined by the dimension if the biome_music component or music_definition property is left off. An empty string can be used if the biome is intended to be silent

Mobs

• Farm animal spawn eggs used in the Mangrove Swamp biome will now spawn the same variants of Chicken, Cow, and Pig as seen in the Java Edition (MCPE-190750)

User Interface

• Worlds are no longer missing from the Storage menu
• Bundle tooltip no longer sometimes renders as if having a different amount of items
• Adding "Manage Storage" button if download fails due to lack of space with instructions on what needs to be cleared out
• Adding "Clear Download Cache" button to storage for clearing files that got stuck due to a downloading error
• Auto clearing the download cache on startup if it detects that it is running out of space

Components

• Content errors will log missing texture references in the "minecraft:icon" item component
• The "minecraft:rideable" component's Seat definition now has two additional fields:
• "third_person_camera_radius" can be used to set a different camera radius when in third person or third person front camera. The value needs to be in the range [1.0, 64.0]. Value 0.0 is ignored
• "camera_relax_distance_smoothing" adds springiness to the camera movement when the camera moves back to its radius after being pushed closer to the player by and obstacle. A higher value means a stiffer spring. The value needs to be in the range [1.0, 32.0]. Value 0.0 is ignored
• The "minecraft:leashable" component now support multiple presets:
• A list of presets can be defined in the new "presets" field
• Each preset determines how the entity behaves when leashed to another entity
• A preset is selected when the entity is leashed and remains active until it is leashed to something else
• The first preset whose "filter" conditions are met will be applied
• If no presets match, a default configuration is used instead
• The following fields are now part of each preset:
• "filter": Defines the condition that selects this preset out of all the presets upon leashing
• "soft_distance": Distance at which the spring effect begins
• "hard_distance": Distance at which the leash stiffens
• "max_distance": Distance at which the leash breaks
• "can_be_stolen": Determines if a player can steal the leashed entity using a Lead

Editor

• Added a new toggle group for Trim Actions
• Added 2 new trim actions Trim (shrink the selection bounding volume to include only the specified non-air blocks) and Remove Air(remove all air blocks (and specified blocks) from the selection to create a new selection containing only the specified blocks)
