Fedora 27 is due to be officially released in November. Meanwhile I upgraded one of my systems to the pre-release of Fedora 27 beta. The first time I tried it the upgrade failed. All the packages downloaded and when I tried to reboot into install mode I would get the message "Upgrading...this will take a while" and then it rebooted back into Fedora 26. Then I tried it again the net day and the upgrade worked flawlessly. So far Fedora 27 seems solid, stable and didn't break any of my software. Normally I wait to the official releases but of late I have been jumping ahead and upgrading the beta pre-releases.
