I have been using Fedora since Fedora 20, and I've always been leery of upgrades from hearing all the hit and miss stories, but I was curious when I heard Fedup was being killed for a DNF method that's supposed to be better. A while back I did an F22 Cinnamon to F23 upgrade with (apparently) no problems. I decided to try it out again going from F23 to F24 beta on my main computer and I have to say I have experienced no issues. RPMFusion doesn't work but I knew what to expect when upgrading to a beta
So having 2/2 successes, I think I am thoroughly happy with keeping Fedora on my main laptop
So good job and thank you to the folks who have been working on DNF and everything else that made these upgrades seamless!
