Release Notes

## New Features ##

### Updated Google Package Dependencies ###

Xamarin.Forms on Android now depends on GooglePlayServices 29.0.0.1 for maps and Xamarin.Android.Support.v4 (and friends) at 32.1.1.1.

### Margins ###
Adding margin support is intended to allow users to reduce the overall depth of their layout hierarchies by allowing more complex layouts with fewer wrapping views.
`public Thickness Margin { get; set; }`

### UWP Maps ###

UWP Maps are now supported, just like other platforms.

### CarouselView ###

CarouselView is intended to fully replace CarouselPage. CarouselPage will be deprecated in a future release. CarouselView is superior in many ways, including its ability to be virtualized and nested within layouts.

### Nest platform controls to Forms layout ##
Allows adding platform-specific controls (iOS, Android, and Windows) directly to a Forms layout. Note: this isn't available from PCL and requires #if defines to work from a shared project.

### 2D ScrollView Support ###

`scrollView.Orientation = ScrollOrientation.Both`

### AutomationId Support ###

Xamarin.Forms now has first class support for setting automation identifiers for usage with Xamarin UITest or other testing frameworks. Simply setting the AutomationID property should allow the automation framework to find and interact with your controls.
