Where can I find documentation for older versions?

I can't find any documentation for syntax in older versions (specifically 5.7.6) - I need to force acceptance of a host key and can't find the syntax (this new version is radically different).

1) Always use the latest version! It's a security software, you cannot afford using an old version.
2) I do not think, there's any difference between 5.7.x and the 5.11.x regarding host keys.

So what is your problem exactly?

1) no. No time at present to move to/learn new syntax and no it's not a security risk in this closed environment. Take the word of a CISSP on this.

2) Can you just answer the simple question - where is documentation for versions prior to this MAJOR revision? I need to update a script to do something slightly different, I'm in a hurry and I don't understand your being obstinate on answering a simple question.

WinSCP's major drawback has always been subpar documentation that is difficult to find what you need.

WinSCP has in-app documentation to scripting. Use help command.
Of you can scan through old revisions of on-line documentation.
Though again, there is no difference between 5.7.x and the 5.11.x regarding host keys, or basically about any scripting functionality (apart from a new functionality).
Incompatible changes are documented here:
https://winscp.net/eng/docs/incompatible_changes
(and note that there are hardly any)

Well, one of the thinks, people praise WinSCP for the most often, is the excellent documentation. :)
