Reviews of outdated versions should have an indication
When reviewing an application, the review should only be valid for the version of the app that was installed at the time of the review. When a newer version of the app is available, the reviews for older versions should somehow be marked as outdated. This could maybe be done by adding a little icon to those reviews.
Are we saving the version that was reviewed in the review metadata right now? If we're not, we'd have to figure out how to deal with all the existing reviews.
