Is the most recent draft. Discussion of the protocols occurs on the
ietf-secsh at netbsd.org mailing list.

I don't know of any server implementations that do filexfer-05. Perhaps
some of the commercial ones do, but I haven't checked (and won't
without licenses to do so).

If it wants to interoperate with the majority of deployed software, any
implementation that supports filexfer-05 will also have to support
filexfer-03.

Therefore I don't see a point in implementing the new draft until some
issues are cleared up (including an O_NOFOLLOW equivalent for opening
files) because then we would have to implement filexfer-03, 05 and
whatever replaces it.

The new draft is an improvement in a few areas, though. One of them
being the transmission of user/group info.
