Mojang has launched the beta and preview version 1.21.80.27 for Minecraft Bedrock Edition. This update comes in the wake of the recent Minecraft Live 2025, where features like the cheerful ghast and the vibrant visuals were introduced as part of the Summer Game Drop.
As this beta follows a significant prior update, it primarily focuses on enhancements and refinements rather than new features. The latest version emphasizes improvements to the Vibrant Visuals, while incorporating various bug fixes and technical modifications.
Below are the detailed patch notes for Minecraft Bedrock 1.21.80.27 beta and preview.
Minecraft Bedrock 1.21.80.27 Patch Notes: Comprehensive Overview
New Experimental Features
Gameplay Enhancements
- Introduced the ‘minecraft:replace_biomes’ component, enabling the customization of biomes by replacing sections of vanilla landscapes. This feature can be accessed by adding it to custom biome files within behavior packs.
