+## 1.0.0 - Out of developer preview  🎉.
+
+* Bump the minimal Flutter SDK to 1.22 where platform views are out of developer preview and performing better on iOS. Flutter 1.22 no longer requires adding the `io.flutter.embedded_views_preview` to `Info.plist` in iOS.
+
 ## 0.5.33
 
 * Keep handling deprecated Android v1 classes for backward compatibility.

 A Flutter plugin that provides a [Google Maps](https://developers.google.com/maps/) widget.
 
-## Developers Preview Status
-The plugin relies on Flutter's new mechanism for embedding Android and iOS views.
-As that mechanism is currently in a developers preview, this plugin should also be
-considered a developers preview.
-
-Known issues are tagged with the [platform-views](https://github.com/flutter/flutter/labels/a%3A%20platform-views) and/or [maps](https://github.com/flutter/flutter/labels/p%3A%20maps) labels.
-
-To use this plugin on iOS you need to opt-in for the embedded views preview by
-adding a boolean property to the app's `Info.plist` file, with the key `io.flutter.embedded_views_preview`
-and the value `YES`.
-
-The API exposed by this plugin is not yet stable, and we expect some breaking changes to land soon.
-

 ## Usage
