Strange. I got version 2.4 now, with basically same "changle log" as pauldeys screenshot above.
"1. Better image quality 2. Bug fix"
I'll update my camera tomorrow morning and if i got enough time, i'll check what the picture looks like this time.
And now i got answer to one of my earlier questions, i just started roav-app far away from my camera and update notifier was first thing i saw.
