DropZone Doesnt Accept JPG Files

One of my apps uses the DropZone widget and, today, that widget seems to have stopped accepting jpg files.  When I try to upload a jpg file, I get the following message: uploading PNG and GIF files works fine.  Has anyone else see this?  Did I miss an announcement about support of jpg files?

Still works fine on my app. So what has changed? Dropzone itself has not had any update. Has the setting changed for the file-types that are accepted for upload?
