The new version comes with completely replaced compression routines, that additionally provide gzip support (intended for large images). Also the device mode doesn’t require unplugging and resetting the device anymore. Major parts of the I/O code have been redesigned to be prepared for future development. You can find the new version on the download page.
If you want to give feedback, please note, that I will be on holiday for 2 weeks, starting from Tuesday, so I eventually won’t be able to check my mail and approve comments everyday.
