Of course. NTPv4 is the current protocol version, and the software package at https://www.meinbergglobal.com/english/sw/ntp.htm#ntp_stable has been built from the latest stable version of the reference implementation, ntp-4.2.8p10: http://support.ntp.org/bin/view/Main/SoftwareDownloads Anyway, NTPv4 is backward compatible with v3, and in theory even with v2, if any application out there happens to use it. NTP has been designed with backward compatibility in mind, so if a client sends a request with a "v3" version code to an ntpd v4.x server then it also gets a reply with "v3" tn the reply packet. I know there are some other dumb NTP client implementations out there which even put "v1" into the version code of the request packets they send to servers, and even that ones get a valid "v1" reply from ntpd-4.x. So it also depends on your client if you see a v4 "link" on the wire, or not.
