Emu XL-7 & MP-7 User's Group

I think I know the answer to this one, but wasn't 100% sure. Here 
goes: I got my MP-7 with OS 1.01 and I'm ready to upgrade to OS 1.31. 
Question is will I get all the improvements from OS 1.18 too when I 
do this or should I upgrade to OS 1.18 and then go to OS 1.31?

Thanks!
