It's not quite groundbreaking but the newest features on Dropbox mobile is the biggest one in recent memory. These new items help users better communicate with other users while on the move. One of the new features is file activity, which shows you who has viewed, edited, or shared files from your Dropbox. This is available in the web version of the app but according to Dropbox, users have been asking to bring this feature to mobile as well. This feature is available on iOS and should be coming to Android soon. Sharing files should be much clearer in this update but the new interface hasn't launched yet.

iOS users get access to a new commenting system. Instead of taking you to a new window when you want to comment on a file, you'll see a text box at the bottom of the screen in file preview. iOS users are also getting a new gallery view for videos and photos to make it easier to see these files at a glance.
