Copssh version 5.4.0 bundle contains 32/64-bit client/server installers with OpenSSH 7.1, a bug fix release:

Security

• 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.

Bugfixes

• 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 Kocielski.

 Future deprecation notice from OpenSSH:

We plan on retiring more legacy cryptography in the next release including:

• Refusing all RSA keys smaller than 1024 bits (the current minimum is 768 bits)
• Several ciphers will be disabled by default: blowfish-cbc, cast128-cbc, all arcfour variants and the rijndael-cbc aliases for AES.
• MD5-based HMAC algorithms will be disabled by default.

This list reflects our current intentions, but please check the final release notes for OpenSSH 7.2 when it is released.
