Students in your Google Classroom classes now have the option to mark assignments as done even if there is not a document or file to submit. For example, if you assign "read chapter 5" to your students they can mark that assignment as done after completing the reading.
Teachers can now set different permissions for their classes and students in Google Classroom. Teachers can mute individual students in the comment stream or prevent an entire class from commenting. Along the same line, teachers now have the option to sort students by first or last name. Finally, teachers now have the option to download all grades for an assignment at once.
Google Groups can now integrate with Google Classroom. Administrators now have the ability to pre-populate classes using existing Google Groups.
