Let’s say you release a draft of a paper using PDF. But when people open the paper to read it, you’d like the PDF to check whether there’s a more recent version available. If there is, you’d like it to indicate as much — somewhere. Obviously, you could always include a link that says “For the most current version, go here.” But is there a way to say, “A more recent version of this document is available here.”?
