Instructure has created a new tool called DocViewer, which serves the purposes now met by the Box and Crocodoc tools. These are the tools that allow documents to be embedded within Canvas pages (Box) and for instructors to provide inline comments and feedback in student submissions (Crocodoc). Instructure has promised a seamless transition for users.
The switch will occur between June 14 and 24 on the Los Rios production server.
