Hi, I´ve been testing radiusdesk for a while and now i want to upgrade the system to the new version. I cant find the instrucctions to make the upgrade, the version i have instaled uses cake3 php and i can see the version 21-01-5 on the system information. I´ve tried the following instructions with no luck: https://radiusdesk.com/docuwiki/getting_started/update Is there any way to upgrade form that version to the latest on github?
