@@ -5,6 +5,7 @@ Changes for users of the library currently on `develop`:
 - Removed `FLAnimatedImage` from .gitmodules.
 - Change `NYTPhotosViewController` to use fullscreen presentation by default, so it causes the presenting view to disappear behind it, i.e. to get `-viewWillDisappear:` and `-viewDidDisappear` called on it.
 - Fix unbalanced calls to begin/end appearance transitions.
+- Modified comment parameter in `NYTPhotosViewController` and `NYTPhotoViewerSinglePhotoDataSource` to match parameter in signature. Removes compilation warning.
