Ted,
Welcome to the forum. I do not believe there has been any updates to the firmware yet, but I will find out for you.
Out of curiousity, is there a particular reason you are asking for an update? Are you having an issue with your 810? Or were you just curious to see if there were ay enhancements yet? If it has to do with your noise issue's I tried to address that it your other thread. Let me know if any of those suggestions help or pertain to your situation.
