This is on you to decide.
You posted here about how to update. Also there is usually no support for outdated Roon software, just current builds. Roon software usually updates itself. If you use one of your Roon clients and look at Settings|About, what is displayed there for you regarding current versions used and updates?
Note: You can post screenshots here.
If Roon can’t self-update you may have to perform a manual installation of the current software, following the installation instructions provided for new installations.
PS: Current build of Roon Bridge is 1.8 b1125.
