Fedora 9 Sulphur was officially released today. The net is abuzz with the news, so I am not going to repeat them here. I actually had the chance to experience the full Fedora 9 release a few days earlier, thanks to a misconfigured update server in Europe. For about a month, I have been using Fedora 9 RC as my main OS and I am loving it. It's one of the best releases ever in Fedora history. So give it a try, you won't regret it.
