My couple month new A830 had version 1.04 so I did the update. The site stated that if your rec has 1.46 I think or newer you were good. I obviously needed it. Changes noticed, "Flat" was default and listed first vs being last on list and "Natural" being default while running ypao. Maybe nothing or maybe something. Color for on screen looks different and clearer for me. Feels good though being updated, fwiw.
