What are you using for Roll hold strength. I haven't flown since I upgraded yet but the Factory setting of 8 seems really low. I was playing with it and going as high as 50 but haven't flown with it yet (snowing). Any other settings you are tweaking with the new firmware?
I didn't tweak a thing and it has never been better. I did some shooting in moderate wind at 100mm APS-C camera and there were only a couple tiny "bumps" in the wind on FFF. That was in the pan. Roll was rock solid.
