Minecraft Beta & Preview 1.21.120.20, posted on September 3, 2025, is a work-in-progress update for Minecraft Bedrock and Minecraft Pocket Edition. These test versions may be unstable, but they let players experience upcoming gameplay tweaks and performance fixes ahead of the public rollout.
The Preview is available on Xbox, PlayStation, Windows, and iOS, while the Beta can be installed on Android through Google Play. If you’re searching for the latest MCPE build with new systems to try, this version delivers a solid batch of improvements.
Gameplay Improvements and Bug Fixes
Blocks and Redstone
This update refines block interactions in several important ways. Tadpoles now spawn correctly in the water block beneath Frogspawn, improving natural mob ecology. Adventure Mode also received a fix that restores reliable block breaking when water is involved.
The Shelf block gets a deeper Redstone + vibration logic: adding or removing power now emits vibrations, and placing, removing, or swapping items triggers different frequencies depending on whether the Shelf is powered. This brings better parity with vibration-aware mechanics and Sculk-based contraptions.
Commands and Core Mechanics
Command users will notice stability upgrades. The Damage command no longer falsely reports failure on Ender Crystals, and /locate biome now points to the correct biome zones. Older worlds also load Sign text properly again, which helps long-running survival saves.
Graphics, Camera, and Sound
Minecraft 1.21.120.20 improves Bedrock rendering with restored Java parity for ambient occlusion on partial blocks. Weather effects such as snow now support TAA upscaling, reducing flicker and shimmer during movement.
Gamma correction is cleaner on PC and consoles, and Creeper textures display correctly in calibration screens under Vibrant Visuals.
Small immersion wins include a slightly adjusted first-person camera when climbing Ladders or Vines, natural attenuation curves for Copper Chest and Copper Golem sounds, and mobs turning subtly transparent if the camera gets too close.
Items, Mobs, and UI
Suspicious Stew appears in Creative Mode with proper effect descriptions. Chicken Jockeys now drop the Lava Chicken music disc when defeated by a player or tamed wolves. Copper Golems behave more consistently, dropping carried items correctly and fixing statue pixels in sitting pose.
The Pocket UI and chat experience were polished: cursor placement in scrolled text fields is fixed, the chat keyboard icon only shows for touch controls, Armor Trim visuals no longer ghost-apply in inventory, and sleep-to-dawn messaging is clearer. Brightness is renamed to Gamma in Vibrant Visuals, with a reset button and a more informative slider.
World Generation Tweaks
Structures no longer generate on top of features at chunk borders, preventing awkward overlaps with trees or terrain details. This quietly improves exploration flow and makes biomes feel more coherent in new seeds.
Technical and Creator Updates (API)
For addon and behavior-pack creators, this beta is a meaningful leap. You can now set dependency versions to "beta" to always pull the latest beta module, and several APIs move out of beta into stable releases, including ScriptBiomeType and Dimension.getBiome().
LootTableManager recognizes looting-enchanted tools correctly, custom blocks above water no longer cull water faces when using non-opaque render methods, and new equipment location support (“main_hand”) lands in filters like all_slots_empty.
Molang receives a large expansion with new easing, lerp, bounce, and elastic math expressions, enabling smoother animation curves for custom entities and UI. Experimental updates add structure-lookup helpers, fresh player event hooks, new control scheme methods, biome query functions for resource packs, and a redesigned local lighting schema aligned with upcoming Vibrant Visuals workflows.
Why Try Minecraft 1.21.120.20 Now?
If you want early access to Bedrock engine improvements, cleaner visuals, refined Redstone behavior, and one of the strongest creator-side API drops of late 2025, Minecraft 1.21.120.20 Beta/Preview is a great test build. It’s especially useful for players who enjoy experimenting with new mechanics and for developers preparing addons for future Minecraft PE releases.
