The Official Feed Viewer Blog
We have published Feed Viewer for Windows 10 three days after the Windows Store was opened for app publishers. It was necessary because Windows 10 did not guarantee the Windows 8.1 application compatibility. In following weeks, we have converged Windows Phone 8.1 and Windows 8.1 user interfaces into the unified Windows 10 responsive interface. This also means that swiping between articles becomes available on tablet PCs too. Developing a Windows Universal App requires to have Windows 10 installed. We have to drop Windows Phone 7.1 support because Windows 10 does not support Windows Phone 7.8 SDK. We also dropped Windows 8 support because Windows 8.1 was released 2 years ago, and the upgrade is free. Feed Viewer for Windows 8.1 and Windows Phone 8.1 is still supported.
