A lot has changed since OpenSSH-6.0 was released. Why worry about OpenSSH-6.0? Because that is the basis for the core functions and options provided by the current AIX openssh.base. As I understand the IBM packaging - the current, better would be to say latest - is based on OpenSSH-6.0 and includes patches to 'repair' CVE issues.

FYI: The current OpenSSH release is OpenSSH-7.5. (I am still using OpenSSH-7.4: a) lazy; b) turns out there is a rather specific requirement for OpenSSH-7.5)

OpenSSH is released in two versions: regular (for OpenBSD) and "portable" (for the rest of us). The portable release is recognized by adding p1 (sometimes p2) after the release name, e.g., OpenSSH-6.0p1 or OpenSSH-7.5p1.

The table shows name, release date and a "few word summary". The release name links to the release document.
