 ## iOS master
 
+- Polygons and polylines now default to using the map view's tint color. ([#4028](https://github.com/mapbox/mapbox-gl-native/pull/4028))

 ## iOS 3.1.0
 
 - The SDK is now distributed as a dynamic framework instead of a static library, resulting in a simpler installation workflow and significantly reduced download size. The framework contains both simulator and device content; due to [an Xcode bug](http://www.openradar.me/radar?id=6409498411401216), you’ll need to strip out the simulator content before submitting your application to the App Store.
