• sv.mask_iou_batch allowing to compute Intersection over Union (IoU) of two sets of masks. (#847)
• sv.mask_non_max_suppression allowing to perform Non-Maximum Suppression (NMS) on segmentation predictions. (#847)
• sv.CropAnnotator allowing users to annotate the scene with scaled-up crops of detections. (#888)

🌱 Changed

• sv.ByteTrack.reset allowing users to clear trackers state, enabling the processing of multiple video files in sequence. (#827)
• sv.LineZoneAnnotator allowing to hide in/out count using display_in_count and display_out_count properties. (#802)
• sv.ByteTrack input arguments and docstrings updated to improve readability and ease of use. (#787)

[!WARNING]
The track_buffer, track_thresh, and match_thresh parameters in sv.ByterTrack are deprecated and will be removed in supervision-0.23.0. Use lost_track_buffer, track_activation_threshold, and minimum_matching_threshold instead.

• sv.PolygonZone to now accept a list of specific box anchors that must be in zone for a detection to be counted. (#910)

[!WARNING]
The triggering_position parameter in sv.PolygonZone is deprecated and will be removed in supervision-0.23.0. Use triggering_anchors instead.

• Annotators adding support for Pillow images. All supervision Annotators can now accept an image as either a numpy array or a Pillow Image. They automatically detect its type, draw annotations, and return the output in the same format as the input. (#875)

🛠️ Fixed

• sv.DetectionsSmoother removing tracking_id from sv.Detections. (#944)
• sv.DetectionDataset which, after changes introduced in supervision-0.18.0, failed to load datasets in YOLO, PASCAL VOC, and COCO formats.
