The SANE standard version 2 is currently under development. It shouldn't be used yet for production software because some important parts are still missing. Most of the work to update the standard has been done by Andreas Beck and Oliver Rauch. The discussion takes place on the sane-standard mailing list. The standard is in CVS, see CVS page. The SANE2 standard is in branch DEVEL_2_0_BRANCH-1. Use the following command to get this branch:
export CVS_RSH=ssh cvs -z3 -d:ext:developername@cvs.alioth.debian.org:/cvsroot/sane co -d sane2 -r DEVEL_2_0_BRANCH-1 sane-backends
There is a TODO list and some snapshots of the standard are available in several formats:
