SMC change with Yosemite?

[Ly-am]

Hi all,
I'd like to know if installing yosemite, also from external unit, might change the smc firmware.
Thanks if you could check it in system informations, I know that last smc firmware for imac 2013 is 2.15f2, right?

System Report is showing SMC Version 2.15f5 for me.

EDIT:

On Late 2013 27" iMac

Thanks, are you a developer?
It's not possible to restore the default one?
