We (PuTTY) don't.

However, Martin Prikryl (WinSCP author) mentioned the following to us
in April:

| I also now cooperate with Erwin Bolwidt, who develops Java SFTP5
| server. At least his SFTP4 implementation is almost complete. You may
| ask him to send you the beta version.
| http://www.klomp.org/ejb/

I've had a quick nose round that site just now, and didn't find
evidence one way or the other.

On Martin's own web site, he mentions v5:

| Experimental support for version 5 of SFTP (SSH File Transfer
| Protocol). Currently it brings only better error reporting. In future
| the upgrade may allow file verification using MD5 algorithm. Note that
| as I do not know any server supporting SFTP5, the funtionality was not
| tested at all.

Sounds like you should probably bump the version number.


Incidentally, is anyone interested in my proposal to give the server
the ability to advise the client whether opening in FXF_TEXT mode is
advisable? (<20030926223441.GA16719%chiark.greenend.org.uk@localhost> about a
year ago.) If so, I'm willing to dust it off.
