Apple yesterday updated its iTunes U education app with some notable new annotation and media sharing features.
In an extension of iTunes U's markup support, which was previously limited to PDF documents, version 3.5 of the app now enables users to apply visual notes to image files using the same annotation toolset.
Elsewhere, video messages can now be shared between teachers and students, while the ability to open audio and video files in other apps has also been included.
The update comes on the heels of changes earlier this week to Apple's Classroom app, which lets teachers set up iPads for educational settings. That update gave educators the ability to create classes manually and send invitation codes to students for them to join, as well as extending classroom file sharing options with AirDrop support.
