New Fedora 11 Leonidas is out, you can get it here, read installation guide first.
General upgrade how-toes: It is not possible to upgrade directly from Fedora 9 to Fedora 11. To upgrade Fedora 9 to Fedora 11, upgrade to Fedora 10 first.
Special KDE edition and PowerPC editions available. Please use Fedora bit-torrent tracker to get distribution ISOs. Bit-torrent is a preferable way to get Fedora as soon as it does not overload public servers.
I am going to install Fedora 11 on my spare laptop (Dell D820) during the nearest week-end, my impressions to be posted to this blog.
