Some notable changes, from upstream's release notes:
- sshd(8): Remove support for obsolete "host/port" syntax.
- ssh(1): When prompting whether to record a new host key, accept the key
fingerprint as a synonym for "yes".
- ssh-keygen(1): when acting as a CA and signing certificates with an RSA
key, default to using the rsa-sha2-512 signature algorithm.
- ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa"
(RSA/SHA1) algorithm from those accepted for certificate signatures.
- ssh-sk-helper(8): this is a new binary. It is used by the FIDO/U2F
support to provide address-space isolation for token middleware
libraries (including the internal one).
- ssh(1): this release enables UpdateHostkeys by default subject to some
conservative preconditions.
- scp(1): this release changes the behaviour of remote to remote copies
(e.g. "scp host-a:/path host-b:") to transfer through the local host
by default.
- scp(1): experimental support for transfers using the SFTP protocol as
a replacement for the venerable SCP/RCP protocol that it has
traditionally used.
Additional integration work is needed to support FIDO/U2F in the base
system.
Deprecation Notice
------------------
OpenSSH will disable the ssh-rsa signature scheme by default in the
next release.

Login class-based restrictions were introduced in 5b400a39b8. The
code was adapted for sshd's Capsicum sandbox and received many changes
over time, including at least fc3c19a9fc, bd393de91c, and
e8c56fba29.
During an attempt to upstream the work a much simpler approach was
suggested. Adopt it now in the in-tree OpenSSH to reduce conflicts with
future updates.

Compatibility with existing OpenSSL versions is maintained.
Upstream commits:
482d23bcac upstream: hold our collective noses and use the openssl-1.1.x
48f54b9d12 adapt -portable to OpenSSL 1.1x API
86e0a9f3d2 upstream: use only openssl-1.1.x API here too
a3fd8074e2 upstream: missed a bit of openssl-1.0.x API in this unittest
cce8cbe0ed Fix openssl-1.1 fallout for --without-openssl.
Trivial conflicts in sshkey.c and test_sshkey.c were resolved.
Connect libressl-api-compat.c to the build, and regenerate config.h

This completely removes client-side support for the SSH 1 protocol,
which was already disabled in 12 but is still enabled in 11. For that
reason, we will not be able to merge 7.6p1 or newer back to 11.
Upstream did this a long time ago, but we kept DSA and SSH1 in FreeBSD for
reasons which boil down to POLA. Now is a good time to catch up.
