I think it’s up to you, but if you correct a post you should always make it explicit that you have done so and say what you did. Like Lumifer, I think it’s better to add a note at the end (or, in extreme cases, at the beginning) than just to overwrite the old content with the new; otherwise you risk making other people’s comments nonsensical.
