Following MBS-3192, release pages now also show the Discogs master URL links as well as the Discogs release URLs for that particular release (where available). This is confusing at first sight. There should be some kind of way to distinguish between these two types of data. Either a different icon, or a different title for the link, e.g. "Discogs master" for the master URL and "Discogs release" for the release URL, or perhaps a different section for release group URLs to clearly distinguish them from release-specific URLs.
