Full release notes are available at https://www.openssh.com/txt/release-10.3 Selected highlights from the release notes: * ssh(1), sshd(8): remove bug compatibility for implementations that don't support rekeying. 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.
