Beta 126.96.36.199 releases just a day after developer Mojang announced that the cave generation changes that were already implemented on the Java Edition were being reverted and postponed until part two of the Caves & Cliffs update, which is set to release at the end of the year.
Nevertheless, beta 188.8.131.52 has been released on Bedrock, revamping cave and ore generation.
This beta adds a new type of cave known as noise caves that are much larger and more varied than the existing caves (now known as carvers), and introducing varied cave water levels to create flooded areas.
It also updates ore generation to match the new world height, which now goes 64 blocks deeper down than before.
In addition to the underground changes, this beta fixes a few bugs including several crashes.
Although a beta for bug-fix update 1.16.230, its beta versions include Caves & Cliffs features for early testing. These features are behind an in-game toggle and will be removed for the full release of the version.
The beta is available on Xbox One, Windows 10, and Android for users who have entered the beta program on each platform's respective store. The "Experimental Gameplay" toggle must be enabled before creating a world in order to receive the new Caves & Cliffs content.
