There are 3 versions: one for production carts with BW screens, one for production carts with BWR screens and one for prototype carts. If you bought a regular cartridge, you want to go with hf-application-prod-1.3.0.0.zip.
This version mainly adds support for units with BWR (black/white/red) screens
- bwr defaults will be set up
- bwr labels will previewed
- bwr labels can be imported and converted
- bwr labels that I liked the most are included
- firmware updates for bwr can be executed
- also some minor bug fixes
