Soph 9 vs soph 10

How different is the new standards of practice handbook from the 9th edition.

I think typically ten the freshman year, and then hopefully only like or even -5 sophomore.

I’ve read both editions cover to cover. I read v.9 before Level 1 in 2009 and just finished v.10. Although I’m sure there are some small differences, none were noticeable. There is a paragraph in the front of v.10 and on CFAI website about the differences.
