Following that thread, it looks like there is still not any official VPAT documentation, I just wanted to check if there might have been a different issue thread where this documentation has been added. My institution also requires VPAT documentation

Thanks for your post.

No we do not have such document.

I have added this request to the tracker:
Issue 2314 – Voluntary Product Accessibility Template (VPAT) document
You can vote for it there.

My organization needs an assessment of WinSCP's accessibility features according to new legislation in my state. Does WinSCP have a VPAT (Voluntary Product Accessibility Template) to send? Here's a link to learn more about VPATs: https://www.itic.org/policy/accessibility/vpat
