 ### Features
- - The [`SymbolLayer.iconTextFit`](https://docs.mapbox.com/android/api/map-sdk/9.2.0-alpha.1/com/mapbox/mapboxsdk/style/layers/PropertyFactory.html#iconTextFit-com.mapbox.mapboxsdk.style.expressions.Expression-) property now respects the stretch metadata of any nine-part stretchable image passed into the `style.addImage` method. You can define the stretchable area of an image by configuring the `stretchX`, `stretchY`, `content` options on `Style.addImage` to append the requisite [metadata](https://github.com/mapbox/mapbox-gl-js/issues/8917). ([#314](https://github.com/mapbox/mapbox-gl-native-android/pull/314))
+ - Added the `distance` expression for calculating the shortest distance between an evaluated feature and a given GeoJSON object. ([#339](https://github.com/mapbox/mapbox-gl-native-android/pull/339))
+ - The [`SymbolLayer.iconTextFit`](https://docs.mapbox.com/android/api/map-sdk/9.2.0-beta.1/com/mapbox/mapboxsdk/style/layers/PropertyFactory.html#iconTextFit-com.mapbox.mapboxsdk.style.expressions.Expression-) property now respects the stretch metadata of any nine-part stretchable image passed into the `style.addImage` method. You can define the stretchable area of an image by configuring the `stretchX`, `stretchY`, `content` options on `Style.addImage` to append the requisite [metadata](https://github.com/mapbox/mapbox-gl-js/issues/8917). ([#314](https://github.com/mapbox/mapbox-gl-native-android/pull/314))
  - Added methods to set and get the sort key of features in a `CircleLayer` at runtime. Features with a higher sort key will appear above features with a lower sort key. ([#322](https://github.com/mapbox/mapbox-gl-native-android/pull/322))
- - Added `Source.maxOverscaleFactor` for defining the maximum factor by which a parent tile can be overscaled during rendering. This setting is only needed if a custom source on your map appears blurry or distorted when viewed at new zoom levels. ([#299](https://github.com/mapbox/mapbox-gl-native-android/pull/299))
+ - Introduced `Source.setVolatile` to disable ambient caching of tiles from a source. Use this option on transient sources, such as traffic tilesets, if not showing tiles from a source is preferable to showing outdated tiles should an update request fail. ([#355](https://github.com/mapbox/mapbox-gl-native-android/pull/355))
+ - Introduced `Source.minimumTileUpdateInterval` to override the expiration time set via HTTP headers with a longer expiration time on the client. ([#355](https://github.com/mapbox/mapbox-gl-native-android/pull/355))
+ - Added `Source.maxOverscaleFactor` for defining how much a parent tile can be overscaled during rendering. This setting is only needed if a custom source on your map appears blurry or distorted when viewed at new zoom levels. ([#299](https://github.com/mapbox/mapbox-gl-native-android/pull/299))
+
+### User location indicator
+- Introduced an activation option to render the `LocationComponent` with a dedicated OpenGL layer through `LocationComponentActivationOptions#useSpecializedLocationLayer`, instead of the combined symbol and circle layer implementation used by default. ([#319](https://github.com/mapbox/mapbox-gl-native-android/pull/319))
+- Introduced an option to add an animated pulsing circle around the `LocationComponent` through `LocationComponentOptions#pulseEnabled` and methods to customize it. ([#172](https://github.com/mapbox/mapbox-gl-native-android/pull/172))
+- Introduced an option to set a screen area through `LocationComponentOptions#trackingMultiFingerProtectedMoveArea` where executed gestures will avoid breaking camera tracking when `LocationComponentOptions#trackingGesturesManagement` is enabled. ([#356](https://github.com/mapbox/mapbox-gl-native-android/pull/356))
 
 ### Improvements and bug fixes
+ - Improved the default compass engine's heading calculation by accounting for device orientation, ensuring accelerometer and magnetic field sensor events are retained, and pushing updates to the heading even if the sensor is unreliable. ([#338](https://github.com/mapbox/mapbox-gl-native-android/pull/338))（h/t [ystsoi](https://github.com/ystsoi))
  - Enabled adding style images on-demand on `MapSnapshotter`. ([#317](https://github.com/mapbox/mapbox-gl-native-android/pull/317))
+ - Fixed a crash when changing the user interface in `MapSnapshotter.ErrorHandler`. ([#347](https://github.com/mapbox/mapbox-gl-native-android/pull/347))
  - Fixed a crash when calling the `Style.removeImage` method with the name of a nonexistent image. ([#16391](https://github.com/mapbox/mapbox-gl-native/pull/16391))
  - Fixed a crash when encountering an invalid polyline. ([#16409](https://github.com/mapbox/mapbox-gl-native/pull/16409))
  - Certain logging statements no longer run on the main thread. ([#16325](https://github.com/mapbox/mapbox-gl-native/pull/16325))
 
 ## 9.1.0
-
 ### Features
  - Added `within` expression for testing whether an evaluated feature lies within a given GeoJSON object. `within` accepts `Feature`, `FeatureCollection`, `Polygon`, and `MultiPolygon` as valid GeoJSON objects. ([#198](https://github.com/mapbox/mapbox-gl-native-android/pull/198))
  - Added `in` expression for testing whether an item exists in an array or a substring exists in a string. ([#171](https://github.com/mapbox/mapbox-gl-native-android/pull/171))
