 - 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
-

 - Code refactoring
 - Add 'set_roi' and 'reset_roi' services
 - Add parameter 'pos_tracking/depth_min_range'
 - Add parameter 'pos_tracking/set_as_static'

-----------
 - Add 'pos_tracking/set_gravity_as_origin' parameter. If 'true' align the positional tracking world to imu gravity measurement. Keep the yaw from the user initial pose.
 - Add 'pos_tracking/pos_tracking_mode' parameter. Matches the ZED SDK setting: 'QUALITY', 'STANDARD'
 - Fix the warning 'Elaboration takes longer [...]'
-
-2023-09-07
-----------
 - 'pub_frame_rate' now controls the 'InitParameters::grab_compute_capping_fps' parameter of the ZED SDK instead of controlling the frequency of a parallel thread. It's not a Dynamic parameter anymore.
 - Change 'general/camera_flip' parameter to string: 'AUTO', 'ON', 'OFF'
 - Change 'general/verbose' from bool to integer
