If such an implementation tries to interoperate with OpenSSH, it will now eventually fail when the transport needs rekeying. * ssh(1), sshd(8): support IANA-assigned codepoints for SSH agent forwarding, as per draft-ietf-sshm-ssh-agent. Support for the new names is advertised via the EXT_INFO message. If a server offers support for the new names, then they are used preferentially. * ssh(1): add a ~I escape option that shows information about the current SSH connection. * sshd(8): add 'invaliduser' penalty to PerSourcePenalties, which is applied to login attempts for usernames that do not match real accounts. Defaults to 5s to match 'authfail' but allows administrators to block such attempts for longer if desired. * Support the ed25519 signature scheme via libcrypto.

Security * ssh(1): disallow control characters in usernames passed via the commandline or expanded using %-sequences from the configuration file, and disallow \0 characters in ssh:// URIs. New features * ssh(1), sshd(8): add SIGINFO handlers to log active channel and session information. Sponsored by: The FreeBSD Foundation
