This release contains several new features and fixes to the libraries, as well as fixes to the tool:

Fuse Libraries

ITitleNode, TitleChanged, and related title events have been removed. Instead the resource system should be used with a CurrentPageBinding:

<Panel>
       <CurrentPageBinding PageProgress="MyNavigation"/>

       <Text Value="{Page Title}"/>
</Panel>

IPage has been removed as nothing used it or called its functions
NavigationContext can now be set on any node and establishes the context for that tree
Navigation.TryFind now returns an INavigationContext, not a Navigation
CanGoBack trigger renamed WhileCanGoBack
Fuse.Controls.IPageProgress moved to Fuse.Navigation.IPageProgress
If the same element is added again to HierarchicalNavigation it will simply transition to that element now instead of pushing it on the top. This seems to better match the expected use of app navigation. To get the old behaviour set ReuseExistingNode="false" on the navigation.
TriggerAction.Perform was made protected, it should not be called directly. Use the PerformFromNode function.
A generic TriggerAction.TargetNode is available for all triggers now.

the Element.IsLayoutInert boolean has been replaced with a LayoutRole enum. Use LayoutRole.Inert to replicate the old IsLayoutInert true setting
remove unused internal Element.LayoutHappened

CreatePixelFlat factories renamed CreatePoints
CreateAngular factories renamed CreateRadians
Attractor.SimulationType allows specifying which simulation type to use
Attractor.MaxSpeed is no longer available since not all simulation types support it
SmoothSnap.CreatePoints parameters have been tweaked to be a bit slower (this affects EdgeNavigation)
Attractor.TimeMultiplier can be used to increase or decrease the speed of the animation

Renamed ProgressRange to ProgressAnimation to be consistent.
Removed some implementation details from the public API: DiscreteSingleTrack, DiscreteKeyframeTrack, SplineTrack, EasingTrack, IMixerMaster, Mixer

Uno

Added string Uno.Exception.StackTrace property. This is implemented in .NET and C++ targets, and will give you a string similar to System.Exception.StackTrace in .NET.
Uno.Exception.ToString() in C++ will now include the exception type name and stack trace in the returned string (similar to .NET behaviour).
