I check the download area every couple of weeks. I'm a commercial customer and all I can tell you is the only files available to me right now are still the release candidate files.
So I think the answer is "no not yet" but hopefully somebody with more knowledge about when the final release will be published can answer more completely.
I downloaded the release candidate last week and converted a backup database but I had some issues where windows would open without the OS frame. So there was no ability to minimize, drag, resize, close, etc those particular dialog boxes. I didn't spend enough time to know if it was an issue with the RC or something else. I think I'll try to make a call to xTuple since I'm paying maintenance and if I get a better answer, I'll post it here.
