 - Added a `FocusableButton` gui control to simplify creating menus with keyboard navigation ([Flux159](https://github.com/Flux159))
 - Added `focus()` and `blur()` functions for controls that implement `IFocusableControl` ([Flux159](https://github.com/Flux159))
 
+### General
+
+- Added static CenterToRef for vectors 2/3/4  ([aWeirdo](https://github.com/aWeirdo))

 ### Materials
 
 - Added an `OcclusionMaterial` to simplify depth-only rendering of geometry ([rgerd](https://github.com/rgerd))

 ## Bugs
 
 - Fix issue with the Promise polyfill where a return value was expected from resolve() ([Deltakosh](https://github.com/deltakosh))
+- Fix an issue with keyboard control (re)attachment. ([#9411](https://github.com/BabylonJS/Babylon.js/issues/9411)) ([RaananW](https://github.com/RaananW))
 
 ## Breaking changes
+
+- Use both `mesh.visibility` and `material.alpha` values to compute the global alpha value used by the soft transparent shadow rendering code. Formerly was only using `mesh.visibility` ([Popov72](https://github.com/Popov72))
