[#11046](https://github.com/mapbox/mapbox-gl-native/pull/11046) * The layout and paint properties on subclasses of `MGLStyleLayer` are now of type `NSExpression` instead of `MGLStyleValue`. A new “Predicates and Expressions” guide provides an overview of the supported operators. ([#10726](https://github.com/mapbox/mapbox-gl-native/pull/10726)) * Added an `MGLComputedShapeSource` class that allows applications to supply vector data to a style layer on a per-tile basis. ([#9983](https://github.com/mapbox/mapbox-gl-native/pull/9983)) * A style can now display smooth hillshading and customize its appearance at runtime using the `MGLHillshadeStyleLayer` class. Hillshading is based on a rasterized digital elevation model supplied by the `MGLRasterDEMSource` class.

[#11046](https://github.com/mapbox/mapbox-gl-native/pull/11046) * The layout and paint properties on subclasses of `MGLStyleLayer` are now of type `NSExpression` instead of `MGLStyleValue`. A new “Predicates and Expressions” guide provides an overview of the supported operators. ([#10726](https://github.com/mapbox/mapbox-gl-native/pull/10726)) * Added an `MGLComputedShapeSource` class that allows applications to supply vector data to a style layer on a per-tile basis. ([#9983](https://github.com/mapbox/mapbox-gl-native/pull/9983)) * A style can now display smooth hillshading and customize its appearance at runtime using the `MGLHillshadeStyleLayer` class. Hillshading is based on a rasterized digital elevation model supplied by the `MGLRasterDEMSource` class.
