 # ComfyUI-RMBG Update Log
+## V2.9.1 (2025/09/12)
+- Refactored `LoadImage` & `LoadImageAdvanced` Nodes
+  - Reworked resizing logic for more powerful and intuitive control.
+  - New execution priority: `megapixels` has the highest priority, otherwise `size` and `scale_by` now work together in a pipeline.
+  - Improved image quality by calculating the final target size first and performing only a single `resize` operation to prevent quality loss.
+
+- Added `METADATA_TEXT` Output to `LoadImageAdvanced`
+  - The `LoadImageAdvanced` node now outputs the embedded generation parameters from AI-generated PNG files (e.g., prompts, model, seed).
+  - This allows for easy workflow replication by connecting the metadata directly to text inputs.
+
+- Enhanced the RMBG node to optimize batch processing of images and videos, **(User request [#99](https://github.com/1038lab/ComfyUI-RMBG/issues/100) )**
+
+- Reconstructed the `ColorWidget` to improve stability and prevent potential freezes in certain ComfyUI configurations.
