Hi Tord, we discussed this already and we have decided not to add this to the protocol. We didn't want to make any difference between the old and new UCI as I have posted already elsewhere here in this thread. The old and new UCI should be 100% compatible (except for ucinewgame :-), so we saw no need to add a version number to the protocol. In our opinion a new version number would only make it more complicated.
