Release Notes

## Important Notes ##

This is a feature release. As such unlike a patch version bump, the minor version bump indicates the inclusion of new APIs. There should be no breaking changes; however with all feature work, there is the potential for the inclusion of instability. Please help us beta test this release and let us know of any issues you run across.

## New API ##

### ScrollView ###

It is now possible to detect the current scroll offset of the ScrollView. These are readonly bindable properties.
```csharp
public double ScrollX { get; }
public double ScrollY { get; }
```

There are also methods which can be used to perform scrolling in the ScrollView.
```csharp
public Task ScrollToAsync (double x, double y, bool animated);
public Task ScrollToAsync (Element element, bool animated);
```
The `Element` passed to `ScrollToAsync` must be a descendant of the `ScrollView` but does not have to be a direct child.

Finally for those who do not wish to use bindings to observe scrolling, there is a `Scrolled` event that fires when `ScrollX` or `ScrollY` are updated.
```csharp
public event EventHandler<ScrolledEventArgs> Scrolled;

public class ScrolledEventArgs : EventArgs
{
   public double ScrollX { get; } = 0;
   public double ScrollY { get; } = 0;
}
```
Lastly ScrollView no longer uses any internal API to communicate between the frontend and the renderer. `IScrollViewController`, which is implemented explicitly on ScrollView can be used to trigger these and other events.

### ListView ###

**Separator Enhancements**
It is now possible to enable/disable separators for the ListView. This can be configured via the `SeparatorVisibility` property, which is bindable.
```csharp
public SeparatorVisibility SeparatorVisibility { get; set; } = SeparatorVisibility.Default;

public enum SeparatorVisibility {
   Default = 0,
   None = 1,
}
```
Currently there is no option for `Always` as not all platforms have separators as part of their UX. We are considering adding this in the future, however it would be an invented paradigm for Windows platforms.

It is now possible to apply a `Color` to the separator in ListView.
```csharp
public Color SeparatorColor { get; set; } = Color.Default;
```
The default value is `Color.Default` and will function unchanged from the 1.3.0 implementation if left untouched. RGBA values are supported. This function does nothing in `SeparatorVisibility` is set to `None`. Please note that setting either of these properties on Android after loading the `ListView` incurs a large performance penalty.

**Header/Footer**
`ListView` has also grown both a Header and a Footer. These are managed through a series of properties which enable everything from simple usage to more complex MVVM style usage. With Header/Footer the primary reason developers have in the past been forced to put ListViews inside of ScrollViews is finally dead! If you are still placing a ListView inside a ScrollView we strongly suggest you consider porting.
```csharp
public object Header { get; set; } = null;
public DataTemplate HeaderTemplate { get; set; } = null;
public object Footer { get; set; } = null;
public DataTemplate FooterTemplate { get; set; } = null;
```
It is important to note that Header or Footer may be set directly to a View and the Template properties left null. This will cause the Header/Footer to be directly consumed by the renderer. All of these properties are bindable.

**Pull To Refresh**
PullToRefresh has been enabled on all current target platforms for ListView. To enable PullToRefresh in your app simple set `IsPullToRefreshEnabled` to true and make sure you respond to the correct events. It is important to note that this is the "easy" version of this API, in the future a more complete API with a standalone View may be added.
```csharp
public event EventHandler Refreshing;

public bool IsPullToRefreshEnabled { get; set; } = false;
public bool IsRefreshing { get; set; } = false;
public ICommand RefreshCommand { get; set; } = null;

public void BeginRefresh ();
public void EndRefresh ();
```
When the user triggers a `PullToRefresh` the Command will be invoked and the `Refreshed` event emitted. `IsRefreshing` will be set to true. The `ICommand.CanExecute` property is respected. The user must either call `EndRefresh` or assign `IsRefreshing` to false in order to end the refresh state.

All control parameters for these features and more are exposed through the IListViewController interface, which is explicitly implemented on ListView. This will assist those wishing to modify how these features work in custom renderers.

The Windows Phone implementation of PullToRefresh is a custom implementation as there is no platform idiom for doing this. In the future if the Windows platform decided to add a method of doing PullToRefresh by default, we intend to port.

### Forms.Application ###

The `Application` class now exposes 4 new events for dealing with Modal navigation.
```csharp
public event EventHandler<ModalPushedEventArgs> ModalPushed;
public event EventHandler<ModalPoppedEventArgs> ModalPopped;
public event EventHandler<ModalPushingEventArgs> ModalPushing;
public event EventHandler<ModalPoppingEventArgs> ModalPopping;
```
The `ModalPoppingEventArgs` contains a `Cancel` property which if set to true will cancel the Pop event and cause the application to enter the background (the operating system is informed of the unhandled back event).

In order to implement this feature, all pre-Application methods of creating a Forms app have been updated to create a default `Application` which is set as the root pages `Parent`. It is possible this may cause issues in some edge cases, if you have any issues please file a bug report. It is suggested you update your app to the new LoadApplication initialization methodology if possible.

Application now has a method of manually forcing the `Properties` dictionary to be saved to the IsolatedFileStore. This is to allow users to save their properties when it makes sense for them rather than risk them not getting serialized out due to a crash/being killed by the OS.
```csharp
public Task SavePropertiesAsync ()
```

### OpenGLRenderer ###

On Android `OpenGLRenderer` has been renamed `OpenGLViewRenderer` for consistency.

### Layout ###
Layout now contains a `ILayoutController` class which has an `IReadOnlyList<Element>` which can be used to enumerate the children of a Layout regardless of the type of the Layout.
