New Features:

Respawn Blocks Explode Game Rule

  • Added the "Respawn Blocks Explode" game rule, which can be used to prevent Respawn Anchors and Beds from exploding (MCPE-76687)

Structure Block: Corner Mode

Experimental Features:

More experimental features from Caves & Cliffs: Part II are available in this update and can be enabled on the world creation screen!

Please keep in mind that these features are work in progress, still under in development, and subject to change. If you activate them, your world might crash, break, or not work with future updates. Experimental features cannot be turned off after world creation.

For more information, please see the article about enabling experimental features at aka.ms/MCExperimentalFeatures.
