Per /usr/share/doc/openssh-client/NEWS.Debian.gz (which apt-listchanges
would show to you automatically):
openssh (1:7.1p1-2) unstable; urgency=medium
OpenSSH 7.0 disables several pieces of weak, legacy, and/or unsafe
cryptography.
* Support for the legacy SSH version 1 protocol is disabled by default at
compile time. Note that this also means that the Cipher keyword in
ssh_config(5) is effectively no longer usable; use Ciphers instead for
protocol 2. The openssh-client-ssh1 package includes "ssh1", "scp1",
and "ssh-keygen1" binaries which you can use if you have no alternative
way to connect to an outdated SSH1-only server; please contact the
server administrator or system vendor in such cases and ask them to
upgrade.
