Here is what's new (since Beta 13.4):

  • Support for custom markup extensions
  • Support for going full-screen via the "Application.Current.Host.Content.IsFullScreen" property
  • Fixed an issue with WCF that sometimes caused an error 500 message when running in the Simulator
  • Fixed an issue where "ToggleButton.Checked" event was raised even though the control was already checked
  • Improved Viewbox reliability

We are also working on many other features and we will release them as soon as they are ready.
