New workshop with older PMMC?

[4DSysFan]

Hello,
I am still running Workshop 3.1.0.14 in conjunction with uVGA Pmmc R25. I haven't upgraded, as I am shipping working code and have not needed the new features (yet).
I would like to upgrade and start playing with VISI, but I want to ensure that everything will still work. As far as is known, if I upgrade workshop/GC/Pmmc, should most of my code still be functional? Do the new Pmmcs consume significantly more flash / ram space than earlier versions?
Thanks!

As far as is known, we have simply fixed existing problems and added new functionality.



The new PmmCs have the same Flash/Ram space
