I was just generally wondering. In my case I uploaded a file as game (in html), so it's a webgame and I didn't try how downloads would look like yet. Still there's an edit-button, where you could update the description also its file and getting the prev. version saved but invisible to users (not marked as download-file there). If you like I could let you know about closer info on discord-pm's about how to update game-versions on itch-platform?
