I have put a new 4.5.492 prerelease online, leading up to the 4.5.500 release.
This prerelease supports WinRT 8.1 and the latest Xamarin Android versions, and includes a number of bug fixes and enhancements people have asked for over the past few weeks.
Please give this version a try ASAP and let me know if you encounter any issues. My plan is to do the final release in about a week barring any major issues you all might find.
