10.1, released 8 August 2022.
What’s new: Added dark mode support. Improved HiDPI font size support.
Minor updates for v10.1:
7 October 2022: Updated the folder selection dialog that opens via the “Browse” button, to fix the issue where some folders were intermittently missing from the list.
20 September 2023: Fixed the minor bug where the file name highlighting was not updated after pressing the “Reset EXIF Orientation to Normal” button.
11 December 2023: Removed the “In the future, do not show me this dialog box” checkbox from the crop warning dialog, because it was stored by Windows in its registry and was difficult for the users to change later. Now the crop warning dialog is controlled only by Options – Display crop warning in JPEG Lossless Rotator.
