@owenjames Here's a screenshot of a solution, let me know if this remedies the problem at hand. We can notify the user about other available versions by a) making the update into a dropdown [like in install], b) adding a badge next to version badge with the number of available versions, and c) amending the microcopy underneath the button to tell the user how many versions they are behind main.
