The 1.21.80.20 Preview for Minecraft Bedrock Edition introduces the Player Locator Bar, which shows the direction of other players on the HUD and replaces the EXP Bar while keeping the Player Level visible. Colored indicators appear when the camera is within 120 degrees of another player, with arrows indicating vertical position. Players can be hidden from the Locator Bar if they are crouching, in Spectator Mode, wearing a Mob Head or Carved Pumpkin, or using a Potion of Invisibility.
The update also includes various bug fixes, such as preventing sapling "age_bit" regression, fixing block collision issues, resolving item usage bugs, and improving mob behavior. Sound issues and stability problems have been addressed, along with several UI enhancements, including control customization for spectators and fixes for menu loading errors. Additionally, there are changes for vanilla parity, such as crafting adjustments and updates to item functionality.
