Spitfire 0.45.0 release notes
Released: 2026-10-18
- **Drift notice**: when a synthetic monitor leaves its living baseline (its last 24 hours are clearly slower, or fail more often, than the 7 days before), the new `monitor.drift` event goes to your notification channels — **once per drift**, with no threshold to set, carrying p95 and the failure rate before and now. It works on Slack, Teams, e-mail, SMS, webhook and issue-tracker channels; existing channels are unchanged — tick it in a channel's **Events** list to receive it. The monitor's page also shows when the drift started.
Updating
Your installation tells you about a new release itself: admins see its notes and the update command for that installation at the top of the UI. The command backs up the database first and keeps the settings (Updating). You can also follow new releases with the RSS feed.
