 - Fixed code signature issues for sandboxed apps by removing entitlements parameter from non-sandboxed builds.
 - Fixed Sparkle framework deep code signing to handle complex framework structure.
 - Fixed missing XPC service entitlements (`com.apple.security.xpc.aConnectionServices`, `com.apple.security.xpc.aStatusServices`) required for Sparkle installer to communicate with sandboxed app.
+- Fixed excessive refresh timer resets by properly cancelling previous subscriptions and validating value changes before recreating timers.
+- Fixed interval indicator to respect user's refresh interval setting instead of always assuming 60 seconds.
 
 ### Changed
 - Re-enabled app sandbox with minimal entitlements (network.client only) for improved security while maintaining Sparkle update functionality.
 - Enhanced Sparkle error logging to include error domain and code information, making update failures easier to diagnose.
 - Updated build script to use `ditto -c -k --keepParent` for creating update ZIPs, which properly preserves code signatures that `zip` command breaks.
+- Removed app sandbox to allow Sparkle to function properly; keeps option to re-enable sandbox later for App Store distribution.
 
 ### Added
 - Added in-app Sparkle update logs in Preferences → Updates tab with Show/Hide toggle for real-time debugging of update operations.
 - Log entries include timestamps and distinguish between info and error messages.
 - Users can clear logs manually and logs persist during the session (max 100 entries).
+- Added status notifications for server monitoring in Preferences → Notifications:
+  - "Status Notifications" toggle: alerts when servers go offline/online or services change status.
+  - "Alert Notifications" toggle: (placeholder for future alert threshold configuration).
+- Ping status changes now trigger notifications (Server Online/Offline).
+- Service status monitoring tracks individual services (DNS, FTP, SSH, HTTP, HTTPS, etc.) and alerts when they go offline or come back online.
+- Notification permissions are requested automatically when the app launches.
 
 ### Previous Changes
 - Flattened the project structure so sources live at the repository root instead of the nested `iKeyMon/` folder and updated the Xcode project accordingly.
