An updated Rubric interface has been made the default in Canvas. These enhanced rubrics come with additional functionality, allowing you to re-arrange rubric lines, quickly duplicate and archive rubrics, allow for student self-assessment, and download a report of rubric assessments.
Differentiation tags is a new feature available in your Canvas course. These tags provide an additional way to group students in your course, without informing them. These tags can be used for gradebook filtering, assigning content to different sets of users and enforcing differentiated due dates.
Note: There is significant overlap between the functionality of tags, sections, and groups. Please refer to this comparison guide to help determine which feature is appropriate for your use case.
