-# Release Note for Cluster4NPU
+# Release Notes - Cluster4NPU 
-## v0.0.2 (2025/7/31)
+
-### Update
+## v0.0.2
-- 
+
-### Fix
+**Release Date:** July 31, 2025
-- Can't inference twice in the same app
+
-- FPS computation
+### Issues Resolved
-- 
+- **App no longer crashes** when running inference multiple times
+- **FPS numbers now show correctly** - no more jumping from high to low values  
+- **System stays fast** during long sessions - memory usage is now controlled
+- **Processing won't get stuck** when too many images pile up
+
+### Improvements
+
+- **FPS Display**: Shows real processing speed (around 4-5 FPS typically)
+- **Memory Usage**: App automatically cleans up old data to stay efficient
+- **Real-time Processing**: Always processes the newest camera images first
+- Removed unnecessary text and confusing messages that cluttered the display
+
+## For QA
+
+### Test These Scenarios:
+1. **Multiple Sessions**: Start and stop inference 3-5 times → Should not crash
+2. **Long Running**: Let it run for 1 hour → Performance should stay consistent  
+3. **FPS Check**: Watch FPS numbers → Should be steady around 4-5 FPS, not jumping wildly
+4. **Memory Check**: Monitor system memory → Should not keep growing over time
+
+### Expected Results:
+- No application crashes
+- Stable FPS readings  
+- Memory usage stays controlled
+- System responds quickly to new camera frames
