+## [2.0.0] - 2025-12-06
+
+### ✨ Added
+- **Modular Architecture**: Restructured entire codebase into organized modules (`src/core`, `src/ui`, `src/utils`)
+- **Kaggle Integration**: Automatic dataset download from Kaggle FER2013
+- **Professional UI**: Cyberpunk-style HUD with emotion probability bars and FPS counter
+- **Video Recording**: Built-in recording feature (press 'r' to toggle)
+- **FPS Counter Utility**: Accurate FPS calculation with rolling average
+- **Fallback Face Detection**: OpenCV Haar Cascade fallback when MediaPipe is unavailable
+- **Configuration System**: Centralized configuration in `src/config.py`
+- **Environment Checker**: Script to validate system compatibility
+- **Test Suite**: Comprehensive testing scripts
+- **Documentation**: Complete README, INSTALLATION guide, and KAGGLE_SETUP guide
+
+### 🔧 Improved
+- **Performance**: Frame throttling for better FPS (analyze every N frames)
+- **Thread Safety**: Proper locking mechanisms for emotion analysis
+- **Error Handling**: Robust error handling with fallback mechanisms
+- **Code Quality**: Type hints, docstrings, and consistent formatting
+- **Compatibility**: Support for Python 3.8-3.13 with compatibility warnings
+
+### 🐛 Fixed
+- Fixed DeepFace result parsing with proper type checking
+- Fixed path resolution issues across different operating systems
+- Fixed camera release on exit
+- Fixed emotion probability normalization
+
+### 📦 Dependencies
+- Added ml-dtypes for TensorFlow compatibility
+- Updated all dependencies with version constraints
+- Created comprehensive requirements.txt
