The message has been there basically forever:

1.41  (markus 02-Jan-01): log("Received disconnect from %s: %d: %.400s", ...

The only thing to have changed semi-recently is that we improved
logging of preauthentication messages in privsep mode in the 5.9
release to no longer need a /dev/log inside the privsep chroot. If
your old OpenSSH version was <5.9 and the /var/empty chroot didn't
have a /dev/log in it then you may have been missing these messages.
