+- **OPTIMIZATION**: Better memory efficiency in dictionary loading operations
+
+### 🔧 Code Quality
+- **IMPROVEMENT**: Fixed Rubocop offenses for better code quality
+- **IMPROVEMENT**: Enhanced code documentation and comments
+- **IMPROVEMENT**: Improved separation of concerns in performance-critical sections
+
+### 📝 Documentation
+- **MAINTENANCE**: Updated code comments for clarity
+- **MAINTENANCE**: Improved inline documentation
+
+### 📦 Dependencies
+- **UPDATE**: text-hyphen 1.4.1 → 1.5.0 (runtime dependency)
+- **UPDATE**: rubocop-rspec 2.31 → 3.8 (development dependency)
+- **UPDATE**: brakeman 6.2 → 7.1 for Ruby 3.1+ (development dependency)
