Version 2.10.0 is available for download.
Changes in this version:
- Publish Service: Added the ability to convert folders to "Super Folders" for managing photos AND other folders inside a Dropbox folder, which Lightroom doesn't support naturally (hence the distinction between collections and collection sets).
- Fixed "HTTP Error Code 400" error when filenames contain Unicode characters.
- Export Dialog: duplicate photos now handled correctly.
- Export dialog: fixed issues with folder caching.
- Other minor fixes.
