The popular Linux distribution Fedora (you know, the one that isn't Ubuntu) has just released a new major version, Fedora 11, around six-and-a-half months after the release of Fedora 10. The changelog is extensive, but the result is an alluring operating system.

For changes more likely to concern you, hit the Changes in Fedora for Desktop Users page for specifics on desktop, network, printing, multimedia, games, and other tweaks. If you give it a go, let's hear how you like the new Fedora in the comments.
