Apps can now have separate changelogs for production, beta and alpha versions

A nice new feature for developers: You're now able to have different changelogs for production, beta and alpha versions of your app. Before it was all or nothing — and nobody wants to see a new changelog for an app without an update. We'll definitely take advantage of this with our next version, which should be available as soon as it's ready. (See what we did there?)
