+DSpace curation tasks and other Java-based helpers used on the [CGSpace](https://cgspace.cgiar.org) institutional repository:
 
 - **CountryCodeTagger**: add ISO 3166-1 Alpha2 country codes to items based on their existing country metadata
+- **FixJpgJpgThumbnails**: Fix low-quality ".jpg.jpg" thumbnails by replacing them with their originals
 
 Tested on DSpace 5.8. Read more about the [DSpace curation system](https://wiki.lyrasis.org/display/DSDOC5x/Curation+System).

 ## TODO
 
 - Make sure this doesn't work on items in the workflow
-- Port to DSpace 6
-  - Remember to bump Gson version!
 - Check for existence of metadata field before trying to add metadata
 - Add tests
