  Message : WinRT: fixed bug whereby SDL would override an app's default orientation WinRT apps can set a default, preferred orientation via a .appxmanifest file. SDL was overriding this on app startup, and making the app use all possible orientations (landscape and portrait). Thanks to Eric Wing for the heads up on this!
