Apple is out today with a new update to its iTunes U app for iPhone and iPad. The latest version of iTunes U adds a document picker that supports cloud services like iCloud Drive as well as others including Dropbox, Google Drive, and Box. Adding documents from non-iCloud services requires having their apps installed and being signed in.

In addition to the new document picker, iTunes U has a few other educational features including closer integration with Apple’s new Classroom app. Check out the full release notes below:
