- Added "Minimal Smoothing" option (previously named Noise Reduction). It restarts the app when enabled/disabled. To avoid loss of images, make sure that no pictures are being processed in background before using the setting.
- Added "Enhanced HDR+" option for portrait mode. It might freeze or crash the app, so use at your own risk. (The Pixel config still needs to be fixed on the OP3/3T.)
