== Experimental ==
These additions and changes are accessible by enabling the "Beta APIs" experimental toggle.
=== Changes ===

*Removed enum {{cd|EntityLifetimeState}} from {{cd|beta}}.
**Move {{cd|setBlockPermutation(location: Vector3, permutation: BlockPermutation): void}} from {{cd|beta}} to {{cd|12.0}}.
**Move {{cd|setBlockType(location: Vector3, blockType: BlockType | string): void}} from {{cd|beta}} to {{cd|12.0}}.

**New {{cd|minecraft:follow_orbit}} preset that is accessible by the {{cmd|/camera}} command and can have a view offset.

;Graphical
*Removed an errant 10 times multiplier in atmospheric scattering in the Deferred Technical Preview.
**This is expected to cause skies in existing packs to become darker and will require content creators to multiply their Rayleigh Strength, Mie Sun Strength, and Mie Moon Strength each by a factor of 10 to achieve the same visual result as before.
*Corrected an issue with the ACES tonemapper in the Deferred Technical Preview on Android. ACES tonemapping should now provide the expected results on Android. This should cause no changes on other platforms.
*Volumetric fog density settings are now supported for weather when a {{cd|format_version}} of 1.21.0 or higher is specified in the Deferred Technical Preview.
