Change in syllabus from Spr 2014 to Spr 2015

I'm wondering if anyone knows if there's been major changes in the syllabus from Spring 2014 to Spring 2015. I have the Spring 2014 EDGE manual and am wondering whether it's worth it to get the new book (there's a chance I'd be paying out of pocket).



Thanks!
