OPNsense release notes need firewall change-control treatment

Firewall updates are operational changes; plugin, routing, and UI improvements still need maintenance windows.

Open original source Submit correction

Why it matters: Firewalls sit on the recovery path for everything else. A small release note can matter if it touches routing, DNS, or VPN behavior.

Summary

  • OPNsense release notes group firewall, routing, plugin, and system changes that can affect more than the web UI.
  • Production and serious homelab firewalls should be updated with backups, known-console access, and a rollback plan.
  • KernelBrief should watch release notes for security fixes, plugin compatibility, and upgrade-path warnings.

Context

Treat firewall coverage as operations guidance, not a vendor announcement rewrite. Link the official release note first.
