Ubuntu 12.10 is now available to download - which is great news for those doing fresh installs. But because Ubuntu 12.04, the release prior to todays, was a Long Term Support release (meaning that it is supported with bug fixes and security updates for 5 years) you won't find a pop telling you that a new version is available. So what to do if you want to upgrade, but don't want to reinstall? We're here to let you know what to do....
