 Changes for users of the library currently on `develop`:
 
+## [4.0.1](https://github.com/nytimes/NYTPhotoViewer/releases/tag/4.0.1)
+
+Changes for users of the library in 4.0.1:
+
 - 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.
