Release notes
## Release Notes: 3.5.5
**What's New:**
This release addresses an important compatibility issue for users with video sources that are not in the standard 16:9 aspect ratio.
### Fixed
- **Improved Compatibility with Non-16:9 Video Inputs**
Previously, mask rendering and region of interest (ROI) alignment could appear incorrect or shifted when using video sources with an aspect ratio other than 16:9. With this update, the scaling and positioning for the ROI calculation have been overhauled to ensure proper centering and scaling regardless of your input video's aspect ratio or dimensions.
The calculations now reference the segmenter’s own target dimensions and center the ROI more accurately, providing a more consistent and visually pleasing background removal effect across all video sources.
### Upgrading
Update as usual—no breaking changes or manual migration steps required.
Thanks for your feedback, and please let us know if you encounter any more edge cases or have suggestions!
