 CHANGELOG
 =========
 
+2023-09-15
+----------
+- Remove start_object_detection and stop_object_detection services
+- Add enable_object_detection service that takes a bool as parameter to enable/disable the OD module (same behavior as in ROS 2 Wrapper)
+- Add parameter 'object_detection/allow_reduced_precision_inference'
+- Add parameter 'object_detection/prediction_timeout'
+- The parameter 'object_detection/model' is no more an integer, but a string with the full name of the supported OD model
+

 ----------
 - Add pose and odometry status publishers

 ### Body Tracking
 The Body Tracking module is not available for the ZED ROS Wrapper. Please consider migrating to the [ZED ROS2 Wrapper](https://github.com/stereolabs/zed-ros2-wrapper) if you need it.
