Hi,  
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?  
Thanks,  
Rebecca
