New Features
RadialGradientBrush
A RadialGradientBrush is drawn within an ellipse defined by Center, RadiusX, and RadiusY properties. Colors for the gradient start at the center of the ellipse and end at the radius.

ProgressRing
The ProgressRing control is used for modal interactions where the user is blocked until the ProgressRing disappears. Use this control if an operation requires that most interaction with the app be suspended until the operation is complete.

TabView updates
The TabView control updates provide you with more control over how to render tabs.
You can set the width of unselected tabs and show just an icon to save screen space:

You can also hide the close button on unselected tabs until the user hovers over the tab (in previous versions it was always shown):

When dark theme is enabled, the background color of TextBox family controls remains dark by default on text insertion (in previous versions, the background color changes to white during text insertion).
