What does the upgrade address? Ie my mods working fine as is so should I bother to upgrade?
Usually fine tuning operation, fixing bugs, adding extra features. With the Polar update it's minor stuff so far. One fix I think is an initial fire up power surge. Another is an option status that blinks that now doesn't blink and a couple other very minor things. If a mod has a v1.0 firmware, then I think it's more of a reason to update than if it's higher since that makes it more likely to be buggy.
