Is the '21-'22 CS Discoveries significantly different than the '20-'21 Course?

I taught the '20-'21 version of CS Discoveries last year. I am teaching CS Discoveries again this year, and I am wondering if there are many changes from the '20-'21 version of the course to the '21-'22 version of the course. Does anyone have any info about how the two versions differ?

Here’s a detailed document showing all of the changes. There were quite a few depending on which units you plan on teaching.
