> What happens to older posts if/when the Markdown interpreter changes

At first, nothing at all. Discourse runs the raw post content through its Markdown parser only when the post is saved, not when it is read.

This “cooked” post text remains untouched unless the post is edited, an admin (or mod?) clicks a special button (which affects that post only) or the server admin runs `rake posts:rebake` (which would rebake _all_ posts in the forum).
