I've been running Fedora-13 for a few months now (after a disaster run-in with Ubuntu). I don't fully (or even minimally, really) understand the release cycle of the OS. I see, according to their website, they release "a new version of Fedora approximately every 6 months and provides updated packages (maintenance) to these releases for approximately 13 months."
If I'm on Fedora-13 now and want to keep pace with the latest and greatest version but I don't want to deal with the bugs from the cutting edge, when should I think about upgrading and what version should I consider upgrading to?
