I saw the upgrade and upgraded before reading the “Special Note” because I thought that the whole point of using Debian was that updates would all be smooth with no worries. After updating, I saw the note.
However, I have no ill effects. System Admin Pro is working fine. Calls are still working. There’s nothing on the GUI to indicate there’s a problem.
I checked the version of Debian and it definitely shows version 13.
I run FreePBX on a Vultr instance, which I update weekly.
Should I be concerned (other than by my obvious recklessness)?
