A few years ago there was some discussion of making duplicity compatible with librsync's new BLAKE2 message digests, but I guess the work has stalled. Btw, the affected packages (btar, rdiff-backup, and duplicity) are the only users of librsync in Guix. So I think there is no reason to update librsync for now.
