Numerous fixes by me and others, seems worth a minor version update. See the CHANGELOG.md file for recent release info and any associated github issues, etc.
There is no HAL anymore, so you'll need to run one of the libgpod tools to prep your device. You should have an ipod-read-sysinfo-extended tool installed with this package, running it once will write a file under your ipod mount point and you should be good to go. Eg:
$ ipod-read-sysinfo-extended /dev/sda /mnt/ipod
Make sure the device and mount point are what you want; see the file README.SysInfo for more details.
