I've finally upgraded my Mandrake 10.0 Community to 10.1 Official. They've apparently introduced a system similar to what RedHat does for updated called Mandrakeonline. I tried registering for it but it looks as if you need to pay some kind of membership in order to download upgrades and what not. Funnily enoughm Mandrakeupdate is still bundled with MCC.
Anyone knows for sure whether you really have to pay for mdkonline?
