+# CHANGELOG
+
+## [Version 1.3.0] - 2025-08-05
+
+### ✨ New Features
+- **Flight Path Boundaries**: Added boundary constraints for synthetic flight path calculations
+- **Configurable Limits**: Set maximum distances (meters) from takeoff in North/East/South/West directions
+- **Automatic Turns**: Drone automatically turns when approaching boundary limits
+- **Enhanced Modal**: Flight path calculation now includes optional boundary input fields
+
+### 🔧 Improvements
+- **Smart Turn Logic**: Gradual turns prevent unrealistic sharp direction changes
+- **Median Speed Fix**: Boundaries prevent wandering issues with median speed calculations
+- **Flexible Constraints**: Each direction can have different boundary distances
+
+### 🐛 Bug Fixes
+- Fixed synthetic flight path wandering problems
+- Improved flight path realism with boundary enforcement
+
+---
+*Added intelligent boundary system for more realistic
