+2026-03-09
+feat: add ErrorTrackerNotifier for email alerts on exceptions
+  - Added error_tracker_notifier dependency (~> 0.2)
+  - Configured email notifications in config/runtime.exs (production only)
+  - Sends exception alerts from alerts@towerops.net to graham@towerops.net
+  - Added to supervision tree in lib/towerops/application.ex
+  - Includes throttling to prevent duplicate error spam
+  - Gracefully shuts down in dev/test (no emails sent)
+  - Files: mix.exs, config/runtime.exs, lib/towerops/application.ex
+
+2026-03-09
+fix: AlertNotificationWorker failing when PagerDuty not configured
+  - Worker was treating {:error, :not_configured} as failure, causing retries
+  - Added graceful handling for :not_configured in all three actions (trigger, acknowledge, resolve)
+  - Now logs as debug and succeeds when PagerDuty integration not set up
+  - Prevents unnecessary error noise in ErrorTracker for organizations without PagerDuty
+  - Files: lib/towerops/workers/alert_notification_worker.ex
+
 2026-03-06
 feat: improve Gaiia webhook setup instructions and descriptions
   - Updated Gaiia provider description to explain what it enables
