Changelog 6.1 introduces a range of new features and improvements, focusing on enhancing platform functionality, refining client-side APIs, and fixing various bugs. Key changes include the removal of Feedback endpoints and the image.crop field across Python, Java, and Javascript clients, as well as the platform and demo portal, simplifying the API structure. The update also adds detection evaluation to the platform and introduces a concept mapping model leveraging knowledge graph relations to enhance user data networks. Bug fixes address performance drops in face predictions and issues with cache invalidation and concept relation deletions. Portal enhancements allow bulk labeling in Explorer mode, display prediction validations, and support multiple concepts per bounding box, while negative tags visibility has been restored. Predict pathway improvements streamline storage interactions and API calls, and video detections now incorporate region predictions from custom models. Additionally, search functionality is expanded with backend support for annotation status searches and connectivity between saved searches and annotation statuses.
