Yes, this is my point - I left my old and previously working sshd_config
with empty VersionAddendum.

This is not true, it will add two quotes to the banner:
SSH-2.0-OpenSSH_6.1_hpn13v11 ""
Default banner (no VersionAddendum in sshd_config):
SSH-2.0-OpenSSH_6.1_hpn13v11 FreeBSD-20120901
So I am fine with:
VersionAddendum -
It will print:
SSH-2.0-OpenSSH_6.1_hpn13v11 -
I don't need really empty addendum, I just don't want to show FreeBSD
version info and empty VersionAddendum was working for me many years.
Now it breaks sshd after final reboot on two of our upgraded servers.
So Release Notes or better UPDATING entry will warn other users before
the same mistake.
Thanks to the remote management / KVM on Sun Fire and Supermicro servers
that I didn't need to drive to the datacenter and I can fix it remotely.
