Release Notes
- Expanded text encoding support for opening/saving files, including UTF-8 (with BOM) plus additional Japanese (Shift_JIS, EUC-JP, ISO-2022-JP, x-mac-japanese), Chinese (GB18030/GBK/GB2312, Big5/Big5-HKSCS, HZ-GB-2312), Korean (EUC-KR, CP949), and more Windows code pages (1250-1258, 874).
- When auto-detection is ambiguous, RibbonDiff now prompts you to Choose Encoding.
- Reload with Encoding to re-open a file from disk using the encoding you select (helps fix garbled text).
- Open two files directly from Terminal / Finder (e.g. open -a RibbonDiff left.txt right.txt).
- Improve filename visibility.
- RibbonDiff is now free to download, with an optional Pro Trial and Pro Lifetime one-time unlock via In-App Purchase. (If you previously bought the paid version, your access should carry over - use Restore Purchases if needed.)
- Performance improvements with faster editing, diff updates and smooth scroll.
- New optional Line Endings (LF/CRLF/CR) and Encoding controls when enabled in Settings.
- Improved drag-and-drop feedback for a clearer, more responsive file drop experience.
