+## 2.0.0
+
+* **Breaking change**. Upgraded to Gradle 4.1 and Android Studio Gradle plugin
+  3.0.1. Older Flutter projects need to upgrade their Gradle setup as well in
+  order to use this version of the plugin. Instructions can be found
+  [here](https://github.com/flutter/flutter/wiki/Updating-Flutter-projects-to-Gradle-4.1-and-Android-Studio-Gradle-plugin-3.0.1).
+* Relaxed GMS dependency to [11.4.0,12.0[
+
 ## 1.0.3
 
 * Add FLT prefix to iOS types
