Change history
See what changed, and put it back.
Configuration changes are versioned. Change history shows what changed, when, and by whom — and lets you revert.
Steps
- Open Settings → Change History (needs the config history capability).
- Find the change. Entries are newest first.
- Read the diff before reverting — a revert is itself a change.
You're done when you can answer "who turned that off, and when".
Gotchas
- Reverting restores configuration, not the work done under it. Putting a routing preference back does not re-run what ran under the previous one.
