I am rather new to Opnsense.
From my general experience with operating systems over more than 40 years, I have learned that it is wise not to update immediately when a new release is offered, like now with Opnsense 18.7.9.
In this context I wonder:
If one does an early update to a new release and finds a new problem, can one revert to the previous version?
