 ### Styles
 
+* Added support for data-driven styling in the form of source and composite style functions. `MGLStyleFunction` is now an abstract class, with `MGLCameraStyleFunction` providing the behavior of `MGLStyleFunction` in previous releases. New `MGLStyleFunction` subclasses allow you to vary a style attribute by the values of attributes of features in the source. ([#7596](https://github.com/mapbox/mapbox-gl-native/pull/7596))
 * Added `circleStrokeColor`, `circleStrokeWidth`, and `circleStrokeOpacity` properties to MGLCircleStyleLayer and support for corresponding properties in style JSON files. ([#7356](https://github.com/mapbox/mapbox-gl-native/pull/7356))
 * Point-placed labels in symbol style layers are now placed at more optimal locations within polygons. ([#7465](https://github.com/mapbox/mapbox-gl-native/pull/7465))
 * Fixed flickering that occurred when manipulating a style layer. ([#7616](https://github.com/mapbox/mapbox-gl-native/pull/7616))

 * Fixed an issue that could prevent a cached style from appearing while the device is offline. ([#7770](https://github.com/mapbox/mapbox-gl-native/pull/7770))

 * Fixed a build error in the static framework flavor of this SDK caused by a missing header. ([#7844](https://github.com/mapbox/mapbox-gl-native/pull/7844))
 * Fixed an issue causing MGLMapView’s `camera`’s `heading` to be set to a negative value, indicating an undefined heading, when the map view faces northwest. The heading is now wrapped to between zero and 360 degrees, for consistency with MGLMapView’s `direction` property. ([#7724](https://github.com/mapbox/mapbox-gl-native/pull/7724))
 * Fixed an issue where MGLMapView could initially flash black before loading. ([#7859](https://github.com/mapbox/mapbox-gl-native/pull/7859))
 * Deprecated the style class methods in MGLStyle. ([#7785](https://github.com/mapbox/mapbox-gl-native/pull/7785))

 This version of the Mapbox macOS SDK corresponds to version 3.4.0 of the Mapbox iOS SDK. The two SDKs have very similar feature sets. The main differences are the lack of user location tracking and annotation views. Some APIs have been adapted to macOS conventions, particularly the use of NSPopover for callout views.
