 ### Styles and rendering
 
+* Added support for 120 frames per second on capable devices. ([#12979](https://github.com/mapbox/mapbox-gl-native/pull/12979))
 * Added an `MGLSymbolStyleLayer.symbolZOrder` property for forcing point features in a symbol layer to be layered in the same order that they are specified in the layer’s associated source. ([#12783](https://github.com/mapbox/mapbox-gl-native/pull/12783))
 * Fixed a crash when a style layer `*-pattern` property evaluates to nil for a particular feature. ([#12896](https://github.com/mapbox/mapbox-gl-native/pull/12896))
 * Fixed an issue with view annotations (including the user location annotation) and the GL map lagging relative to each other. ([#12895](https://github.com/mapbox/mapbox-gl-native/pull/12895))
