Showing some sort of sparkline would be helpful (i.e., overlay major versions with their reviews over time), although may be difficult to convey with the limited real estate. Maybe something to expose if you wanted to dig deeper into the review data (users probably don't care that much for $0.99). I'm guessing this is probably already available to developers anyway?
