Cloned my boot SSD and decided to upgrade to version 8. It all went very well, I rebooted as requested and the login screen came right back.
Looks as though all my docker containers are running fine (I'll see how it goes over the next day or 3)
Very happy to see it working straight out of the box!
Congratulations to the developers on another excellent upgrade and thank you for all the hard work!!!
