I’m upgrading from 4.0.3 with clean iso install. I’ve noticed others in forum speak of their main template. Are they talking about DOM0 template? Is that an option in the installation? because my old version, I think was based on Fedora 26 by default. What would be the advantages/disadvantages of each?
Also, what are the newest versions of Debian & Fedora supported in 4.1 Beta?
