Please use a different formatting for update notes that are written in cards.
I would suggest either placing it under an expandable tag (preferrable) or otherwise make it a much smaller text size so it is easily distinguished from the cards’ answers (sort of like a footnote).
Another advantage of using the expandable tag (on click) system is that theoretically you can make it so that it auto-deletes after the 1 year period has elapsed since a new post, so it’s less work in the long run.
