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/)).


# 2.3.3-pre2

Nuget package [here]().

## New Features

#### Support native view declaration in Xaml

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="https://schemas.microsoft.com/winfx/2009/xaml"
xmlns:ios="clr-namespace:UIKit;assembly=Xamarin.iOS;targetPlatform=iOS"
xmlns:android="clr-namespace:Android.Views;assembly=Mono.Android;targetPlatform=Android"
x:Class="Xamarin.Forms.Controls.XamlNativeViews">
<ContentPage.Content>
<ios:UILabel Text="I'm Native" />
<android:TextView  Text="I'm Native too" />
</ContentPage.Content>
</ContentPage>
```

- native views are automagically wrapped into the appropriate wrapper
- xmlns  defined on a non-matching targetPlatform (see TargetPlatform enumeration) are ignored


#### NativeBindings
Allow binding to Native (non-BP) Views.

Each platform now expose `SetBinding(string propertyName, BindingBase binding)` as an extension method on the respective native views (`UIView`, `Android.View`, `FrameworkElement`).

To get 2-Way Bindings to work, `SetBinding` can take an additional `updateSourceEventName` argument. On iOS, if the Property of the `UIView` is Observable, the `updateSourceEventName` is not mandatory. On [U]WP, something similar is done in order to try to get 2-Way bindings to behave even without the updateSourceEventName.

In addition to this, the platforms also expose `SetValue(BindableProperty property, ...)` and `SetBinding(BindableProperty property, ...)`. Those will have no effect unless the view happen to be directly wrapped in a Xamarin.Forms Layout. In that case, those (attached) BindableProperties will be transferred to the wrapper, allowing this kind of code to be valid.

```
var btn = new UIKit.Button();
btn.SetValue(Grid.RowProperty, 2);

var grid = new Xamarin.Forms.Grid ();
grid.Children.Add(btn.ToView());
```

#### 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)
