Instructure released the news of their updated User Interface back in June 2015 at InstructureCon, but many School District and University Canvas Admins are just now turning on the new feature. UEN, for example, updated their Canvas Interface at the end of August just in time for the start of fall online classes.

Perhaps the best way to explain the changes to the Canvas interface is to think of it like crossing the street in England - always look to the left first. That's where you'll find any real changes to the menus and quick links.
