Elevation Overlays within default component styles have been replaced by the new Tonal Surface Color system. Instead of blending the Primary color with the Surface color based on an elevation value, components will now use a specific Surface color role which can be more easily understood and customized.

Documentation for the affected components and which Surface color roles they use has been updated in 2114a11.
