Release Notes

### Important notes

* Xamarin.Forms 2.3.3 depends on a Xamarin installation of Cycle 8. Users upgrading from Xamarin.Forms 2.3.2 (or earlier) will experience numerous compile errors if they attempt to build without first upgrading their Xamarin installation.
* When upgrading Xamarin.Forms take care not to simply "update all" as that will update the Xamarin.Android.Support packages to an incompatible version. More info [here](https://developer.xamarin.com/guides/xamarin-forms/troubleshooting/).
* In 2.3.3 we are deprecating Classic support (More info [here](https://developer.xamarin.com/guides/cross-platform/macios/unified/)).

## New Features

#### Support native view declaration in Xaml, and native Bindings

The following Xaml is valid, and works as expected:

```
<?xml version="1.0" encoding="UTF-8"?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:ios="clr-namespace:UIKit;assembly=Xamarin.iOS;targetPlatform=iOS"
xmlns:androidWidget="clr-namespace:Android.Widget;assembly=Mono.Android;targetPlatform=Android"
xmlns:formsandroid="clr-namespace:Xamarin.Forms;assembly=Xamarin.Forms.Platform.Android;targetPlatform=Android"
xmlns:win="clr-namespace:Windows.UI.Xaml.Controls;assembly=Windows, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null, ContentType=WindowsRuntime;targetPlatform=Windows"
      x:Class="Xamarin.Forms.Controls.XamlNativeViews">
<ContentPage.Content>
<ios:UILabel Text="{Binding NativeText}" View.HorizontalOptions="Start"/>
<androidWidget:TextView Text="{Binding NativeText}" x:Arguments="{x:Static formsandroid:Forms.Context}" />
<win:TextBlock Text="Foo"/>
</ContentPage.Content>
</ContentPage>
```

- native views are automagically wrapped into the appropriate wrapper
- xmlns  defined on a non-matching targetPlatform (see TargetPlatform enumeration) are ignored
- you can bind to property of native views. A proxy is created on the fly for supporting 2-Way bindings if possible. If the native property doesn't implements INPC, or support Observable (on iOS), or is a DependencyProperty (on UWP), you can pass an `UpdateSourceEventName` parameter to the binding expression.
- if you set, or bind to, attached BindableProperty to a native view that will be wrapped in a X.F.View, those property values and binding are transferred to the wrapper. See HorizontalOptions in the sample above.


#### Platform Specifics
*Introducing Platform Specifics!* Features or behaviors that apply to one platform only can now be implemented without requiring custom renderers. These new features/behaviors can then be accessed easily via a fluent code API or XAML.

Vendors can easily add their own Platform Specifics by attaching Effects to them (see [63a924d](https://github.com/xamarin/Xamarin.Forms/commit/63a924d) and [1f9482e](https://github.com/xamarin/Xamarin.Forms/commit/1f9482e4b5969f19fcde5c691443fcccc848c54e) for complete example).

This feature implements the framework that enables the new API and also includes several examples of platform specific features, which can be previewed using the Platform Specifics gallery page:

* Blur support for any VisualElement on iOS
* Translucent navigation bar on iOS
* Partially collapsed navigation bar (with icons!) on MasterDetailPage on Windows
* Toolbar placement options on Windows
* AdjustResize/AdjustPan on Android (known issue: AdjustResize disables status bar color)
