The seventh edition of the APA Style Guidelines (APA 7e) was released in Fall of 2019. Accordingly, Lethbridge College published an updated copy of its APA Student guide in Fall 2020, shortly followed by a complementary Student Guide to Figure Citation.
Compared to the sixth edition (APA 6e), APA 7e provides simpler formatting and in-text citation for student papers, equity and inclusion updates, and more information on citing digital sources and Traditional Knowledge.
Scribbr published a webpage and a video on the major changes.
The University of Aukland published this comparison chart [pdf].
Dr. Forlenza made a good comparison video that shows 6e on the left and 7e on the right. However, Dr. Forlenza goes over both student and professional papers. If you are a student, you can ignore anything said about professional papers.
For even more detail, the APA Style folks have a video, What’s New in APA Style, and a guide.
