-## Feature
+This release includes deprecations of `ListView`, `Cell`, and `TableView`.
 
-Something about the feature
+## Fullscreen video playback
+
+Now on Android you can play videos fullscreen hosted in a `WebView`. The `iframe` should include `allowfullscreen`.
+
+## Geolocation IsEnabled
+
+Use `IsEnabled` to check if the device has geolocation services enabled independently of requesting location details.
+
+## WebAuthenticator CancellationToken
+
+A `CancellationToken` may now be passed to `WebAuthenticator.AuthenticateAsync` enabling you to programmatically cancel authentication.
+
+## Performance improvements
+
+Various incremental improvements are to runtime performance are included in this release. 
+
+### PropertyMapper improvement benchmarks
+
+Each control handler maps properties to the core controls via `PropertyMapper`s. A new cache has been implemented, and improvements have been made to the order in which properties are applied, thus avoiding some race conditions and repetitive calls.
