 - 2024.09:
   - Added `Re-recognition` and `Auto Save Unsaved changes` features. For usage details, please refer to the "11. Additional Feature Description" in the "2.1 Operational Steps" section below.
   - Added the parameter `--img_list_natural_sort`, which defaults to natural sorting for the left image list. After configuring this parameter, character sorting will be used to easily locate images based on character order.
+  - Add 4 custom model parameters:
+    - `det_model_dir`: Path to the detection model directory
+    - `rec_model_dir`: Path to the recognition model directory
+    - `rec_char_dict_path`: Path to the recognition model dictionary file
+    - `cls_model_dir`: Path to the classification model directory
 - 2022.05: Add table annotations, follow `2.2 Table Annotations` for more information (by [whjdark](https://github.com/peterh0323); [Evezerest](https://github.com/Evezerest))
 - 2022.02: (by [PeterH0323](https://github.com/peterh0323))
   - Add KIE Mode by using `--kie`, for [detection + identification + keyword extraction] labeling.
