@@ -30,7 +30,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Added information about OpenVINO toolkit to login page (<https://github.com/openvinotoolkit/cvat/pull/4077>)
 - Support for working with ellipses (<https://github.com/openvinotoolkit/cvat/pull/4062>)

+- Add YOLOv5 serverless function for automatic annotation (<https://github.com/openvinotoolkit/cvat/pull/4178>)
 ### Changed
 - Users don't have access to a task object anymore if they are assigneed only on some jobs of the task (<https://github.com/openvinotoolkit/cvat/pull/3788>)
 - Different resources (tasks, projects) are not visible anymore for all CVAT instance users by default (<https://github.com/openvinotoolkit/cvat/pull/3788>)
