Can't update my action in the marketplace

I put together an action a while back, as you can see there are several releases:

However in the marketplace the listing shows a very old release as the most recent:

The documentation suggests that I should check a “Publish to marketplace” checkbox when I’m making a new release, but I see no such option when either I push a new tag, or create a new release via the UI.

What am I missing?

I looked at an “official” action, actions/labeler and that provided the clue.

You must now add action.yml inside your repository.  Once that was done I found that I could create a new release, which did then show the “publish to marketplace” text.
