 // ================
 //
 // v0.3 - TBD
-//   - Fixed build for UWP.
+//   - API CHANGE: Introduced the notion of a context. The context is the highest level object and is required for
+//     enumerating and creating devices. Now, applications must first create a context, and then use that to
+//     enumerate and create devices. The reason for this change is to ensure device enumeration and creation is
+//     tied to the same backend. In addition, some backends are bettered suited to this design.
 //   - Null Backend: Fixed a crash when recording.
+//   - Fixed build for UWP.
 //   - Added initial implementation of the WASAPI backend. This is still work in progress.
