 # Changelog
 
+## 2025-09-03 - 5.10.1 - fix(processmonitor)
+Skip null pidusage entries when aggregating process-group memory/CPU to avoid errors
+
+- Add defensive check for null/undefined entries returned by pidusage before accessing memory/cpu fields
+- Log a debug message when an individual process stat is null (process may have exited)
+- Improve robustness of ProcessMonitor.getProcessGroupStats to prevent runtime exceptions during aggregation
+
 ## 2025-09-01 - 5.10.0 - feat(daemon)
 Add crash log manager with rotation and integrate crash logging; improve IPC & process listener cleanup
