Fedora 27 was officially released yesterday, November 14, 2017.
Today I downloaded it and upgraded one of my VMs from Fedora 25 to Fedora 27. That went very well, so I upgraded my main workstation. That went well, too and I am using that workstation to write this post.
It took about 3 hours to do the upgrade using the dnf upgrade plugin. I have written a script that does all the work so I just run that and check up on it later. This upgrade procedure has worked well for the last four version upgrades.
I have only played – er experimented – with F27 for a few minutes but I will try to write a bit more about it soon.,
