Identify ssh client version with more info and sshd server shows it by an env var 

MS Win32 port & build date added in text part of version id ssh client
send to the remote sshd. sshd also shows this string via environment
variable  "SSH_CLIENT_ID" . All these are allowed and encouraged by the
SSH RFC and improves usability and assists users to know what ssh
versions and vendor build they are running.
