## 🔧 Improvements

### Enhanced Object Tracking

- Standardized bounding box formats and better feature handling in BoT-SORT and BYTETracker, making object tracking more robust and maintainable.  
[Thanks to @Rusteam → PR #21509](https://github.com/ultralytics/ultralytics/pull/21509)

### Cleaner Output for Advanced Users

- Progress bars (TQDM) now automatically hide when logging is set above INFO, creating a neater output especially for scripted or production workloads.  
[By @Y-T-G → PR #21538](https://github.com/ultralytics/ultralytics/pull/21538)

### Improved Metrics Documentation

- Expanded and unified docstrings in the `metrics.py` module, making developer and user understanding of metrics best practices easier than ever.
