There are new versions of refractasnapshot, refractainstaller and refracta2usb for jessie/sid. Some of the changes address changes in live-config and syslinux, and some of the changes eliminate the need for gksu. This change was made for those who don't want gksu or its dependencies on their system.
There's a new folder at the sourceforge site for versions that are in testing. The new tools are there now, and there will soon be at least one live iso containing a debian jessie remix that uses sysvinit instead of systemd.
