As always, if you are unsure, be sure check with your professor. The course syllabus is another place to look. Important! Some professors prefer to continue working with the 6th edition for the current semester.
Spring semester 2020 is a transition period for moving from the 6th to the 7th edition. By Fall 2020, the 7th should be the norm, i.e., everyone should be using it.
