Ultralytics v8.3.114 Release: Smarter Object Tracking with Native ReID, Docs & Export Enhancements!
Summary
We’re excited to announce Ultralytics v8.3.114! This release brings robust tracker re-identification (ReID) for object tracking, key improvements in documentation, refined dataset handling, and greater reliability for model export. It’s all about smarter tracking, clearer guides, and smoother deployments. Dive in to experience a more powerful, user-friendly Ultralytics ecosystem! 
New Features
Tracker Re-Identification (ReID) Support
- Native BoTSORT ReID Integration:
Re-identify and reconnect lost objects with advanced feature-based and model-based ReID, now natively built into the BoTSORT tracker. - Automatic, Smarter Association:
The tracker’s new defaultautomode uses YOLO model features for ReID whenever possible—improving tracking in complex scenarios like occlusion and crowd scenes. - More Robust Performance:
Enhanced extraction and association logic ensure tracks can reliably recover lost identities and maintain continuity.

Documentation Enhancements
-
Cleaner Code Blocks:
Code line numbers in documentation no longer include unnecessary links, making copying and navigation easier.
Remove href attributes from code line numbers in Docs code blocks by @glenn-jocher
Refactor code line number links to use <span> tags by @glenn-jocher -
Multispectral Dataset Guides:
Added clear instructions for preparing and using multispectral TIFF images, plus updated dataset size info for DOTA8 Multispectral.
Update coco8-multispectral docs by @Laughing-q
Update dota8-multispectral.yaml by @glenn-jocher
Improvements & Bug Fixes
- Model Export & Metadata:
- The metadata export now always treats the “channels” field as an integer, ensuring greater compatibility with deployment targets like MNN.
Parse channels as int in metadata by @Y-T-G - Logging improvements now show the correct data path for INT8 export calibration.
Restore missing f-string by @Y-T-G
- The metadata export now always treats the “channels” field as an integer, ensuring greater compatibility with deployment targets like MNN.
Purpose & Impact
- Smarter Object Tracking:
The new ReID feature allows trackers to reconnect with lost tracks, boosting reliability in demanding use cases with minimal configuration. - More Accessible Documentation:
Improvements help both beginners and experienced users to get started and troubleshoot issues faster. - Smoother Export & Deployment:
Enhanced export routines lead to fewer errors and confusion when deploying models in various environments.
