 ### CHANGED - Rename video room `Recordings` class to `RoomRecordings`
 
 #### Rationale
-- This was done to avoid a class name conflict with another resource.
-- Client code should be unaffected unless you manipulate the Recording/RoomRecordings class directly. Accessing room recording metadata via the client should work the same way as before.
