Ultralytics v8.3.136 Release Announcement 
Summary
We’re excited to announce Ultralytics v8.3.136, a release focused on making your experience even lighter, faster, and more reliable! This update removes unnecessary dependencies, polishes plotting, optimizes imports, enhances performance, and strengthens documentation and workflow security. Whether you’re deploying YOLO11 on NVIDIA Jetson or running repeated analyses on your laptop, these improvements are designed for you.
New Features & Major Improvements
1. Seaborn Dependency Removed
- Ultralytics is now lighter and simpler to install—
seaborn
is no longer required. - All core plotting is handled via matplotlib.
2. Enhanced Plotting Functions
- Confusion matrix and label plots have been refactored for better performance and improved compatibility, especially for projects with a large number of classes.
3. Performance Boosts
- Utility functions now use internal caching, speeding up repeated operations and improving responsiveness.
- OpenCV imports are now optimized—only loaded when necessary, reducing startup time and memory use.
4. Improved Documentation & User Experience
- The NVIDIA Jetson deployment guide now features comprehensive benchmarks for the Jetson AGX Orin Developer Kit (64GB) and clearer hardware/software requirements.
- Clearer CLI warnings: Invalid task selections in the CLI are more informative and easier to debug.
5. Security Enhancements
- GitHub workflow permissions are now more explicit and secure, ensuring even safer collaboration for contributors.
Why This Matters
- Faster Installs & Fewer Conflicts: A leaner dependency tree means less hassle, faster installations, and fewer compatibility issues.
- Lighter and Faster: Uses less memory and is more responsive, especially for repeated workflows.
- Better Experience: Improved documentation, warnings, and benchmarking to help you deploy models smoothly and troubleshoot efficiently.
- More Secure: Improved workflow management keeps the community and your projects safer.
- Hardware Ready: The latest Jetson guides keep you ahead for embedded or edge deployments.
