Because of recently discovered security flaws, OpenSSH 7.1 is released, just one and a half week after version 7.0. So you can consider this as a bugfix release.
OpenSSH is a 100% complete SSH protocol (version 1.3, 1.5 and 2.0) implementation and includes server support and sftp.
Changes since OpenSSH 7.0
- sshd(8): OpenSSH 7.0 contained a logic error in PermitRootLogin=
prohibit-password/without-password that could, depending on
compile-time configuration, permit password authentication to
root while preventing other forms of authentication. This problem
was reported by Mantas Mikulenas.
- ssh(1), sshd(8): add compatibility workarounds for FuTTY
- ssh(1), sshd(8): refine compatibility workarounds for WinSCP
- Fix a number of memory faults (double-free, free of uninitialised
memory, etc) in ssh(1) and ssh-keygen(1). Reported by Mateusz
