🌟 Summary

v8.4.115 transitions Ultralytics from legacy HUB integrations to the streamlined Ultralytics Platform experience, with simpler authentication and a leaner training codebase. 🚀

📊 Key Changes

  • 🔐 Introduced validated Platform CLI authentication
  • Log in with yolo login API_KEY
  • Remove credentials with yolo logout

  • API keys are checked against the Platform before being saved.

  • 🔄 Added settings migration to schema 0.0.7

  • Existing compatible settings, such as custom dataset and run directories, are preserved.
  • Legacy HUB configuration and incompatible HUB API keys are removed automatically.

  • Users with old credentials are directed to create a Platform API key.

  • 🧹 Removed the legacy ultralytics.hub package

  • HUB authentication, remote training sessions, model loading, exports, dataset utilities, callbacks, and HUB-specific exceptions have been retired.

  • HUB-related API references, documentation pages, navigation entries, and the HUB example notebook were also removed.

  • 🧠 Simplified model and trainer workflows

  • Models no longer load directly from HUB URLs.
  • Training no longer manages HUB sessions, remote checkpoints, heartbeats, or HUB-specific training arguments.

  • Platform callbacks remain available for streaming training information.

  • 📚 Updated documentation and examples

  • Guides, notebooks, CLI help, and API documentation now reference the Ultralytics Platform instead of HUB.

  • Platform authentication and login commands are included in the quickstart and CLI documentation.

  • ✅ Expanded test coverage

  • Added tests for settings migration, API-key validation, login, and logout behavior.

🎯 Purpose & Impact

  • ✨ A clearer user experience: Platform is now the primary destination for dataset management, training, and deployment, avoiding confusion between HUB and Platform services.
  • ⚡ Simpler authentication: The new yolo login command validates credentials directly and provides a more intuitive alternative to manually editing settings.
  • 🛠️ Cleaner and easier-to-maintain code: Removing obsolete HUB components reduces dependencies, integration complexity, and potential maintenance issues.
  • 🔒 Safer upgrades: Existing user settings are migrated instead of being reset, while outdated or incompatible HUB keys are discarded.
  • ⚠️ Compatibility consideration: Applications that import ultralytics.hub, use HUB training sessions, load models from HUB URLs, or rely on HUB-specific utilities must migrate to Ultralytics Platform workflows.

  • 🚀 Recommended next step: Create a Platform API key and authenticate with:

    :::bash yolo login YOUR_API_KEY

For no-code dataset annotation, training, and deployment, use the Ultralytics Platform.
