    • Bugfix: This is primarily a bugfix release.
  • OpenSSH 6.8: March 18, 2015
    • Added new hostkeys@openssh.com extension to facilitate public key discovery and rotation for trusted hosts (for transition from DSA to Ed25519 public host keys)[17]
    • AuthenticationMethods=publickey,publickey to require that users authenticate using two different public keys[18]

2014[edit]

  • OpenSSH 6.7: October 6, 2014
    • The default set of ciphers and MACs has been altered to remove unsafe algorithms. In particular, CBC ciphers and arcfour* are disabled by default.
    • Compile-time option to not depend on OpenSSL[19]
    • Add support for Unix domain socket forwarding
  • OpenSSH 6.6: March 16, 2014
    • This is primarily a bugfix release.
  • OpenSSH 6.5[20][21]: January 30, 2014
    • Added new ssh-ed25519 and ssh-ed25519-cert-v01@openssh.com public key types (available since 2005 but more popular since some suspicious that NSA had chosen values that gave them an advantage in factoring public-keys)[22]
    • Added new chacha20-poly1305@openssh.com transport cipher[23][24]
    • Added curve25519-sha256@libssh.org key exchange
    • FEATURE: ssh, added Match keyword for ssh_config that allows conditional configuration to be applied [25]
    • FEATURE: client-side hostname canonicalisation: CanonicalDomains, CanonicalizeFallbackLocal, CanonicalizeHostname, CanonicalizeMaxDots and CanonicalizePermittedCNAMEs.[26][27]
    • Add a new private key format that uses a bcrypt KDF

2013[edit]

  • OpenSSH 6.4: November 8, 2013 [28]
    • This release fixes a security bug with AES-GCM
  • OpenSSH 6.3: September 13, 2013
    • This release is predominantly a bugfix release
  • OpenSSH 6.2: March 22, 2013
    • Add a GCM-mode for the AES cipher, similar to RFC
    • Added support for encrypt-then-mac MAC modes
    • Added support for multiple required authentication methods
    • Added support for Key Revocation Lists (KRL)

2012[edit]

  • OpenSSH 6.1: August 29, 2012
    • This is primarily a bugfix release.
    • Enables pre-auth sandboxing by default
    • Finds ECDSA keys in ssh-keyscan and SSHFP DNS records by default now
  • OpenSSH 6.0: April 22, 2012
    • This is primarily a bugfix release.

2011[edit]

2010[edit]

  • OpenSSH 5.6: August 23, 2010
  • OpenSSH 5.5: April 16, 2010
  • OpenSSH 5.4: March 8, 2010
    • Disabled SSH protocol 1 default support. Clients and servers must now explicitly enable it.
    • Added PKCS11 authentication support for ssh(1) (-I pkcs11)
    • Added Certificate based authentication
    • Added "Netcat mode" for ssh(1) (-W host:port). Similar to "-L tunnel", but forwards instead stdin and stdout. This allows, for example, using ssh(1) itself as a ssh(1) ProxyCommand to route connections via intermediate servers, without the need for nc(1) on the server machine.
    • Added the ability to revoke public keys in sshd(8) and ssh(1). While it was already possible to remove the keys from authorised lists, revoked keys will now trigger a warning if used.

2009[edit]

  • OpenSSH 5.3: October 1, 2009
  • OpenSSH 5.2: February 23, 2009

2008[edit]

2007[edit]

  • OpenSSH 4.7: September 4, 2007
