We don’t maintain the list of https://github.com/Altinity/ch-stable-versions/blob/c83b2b51e98ea156dd2c31e95c69a41a360f64b8/versions.json#L22-L31 - it contains outdated info and not updated in a timely fashion.

Thanks @alexey-milovidov. Wouldn’t it better to maintain a list of all supported versions(mostly in format of major.minor) in a text(yaml/json) file in server repository? That way, all clickhouse clients can use that as inputs for regression test to ensure backward compatibility.
