+## 0.5.0
+* **Breaking change**. Migrate from the deprecated original Android Support
+  Library to AndroidX. This shouldn't result in any functional changes, but it
+  requires any Android apps using this plugin to [also
+  migrate](https://developer.android.com/jetpack/androidx/migrate) if they're
+  using the original support library.

 ## 0.4.2+1
 * Upgrade Android Gradle plugin to 3.3.0
