Current Musicbrainz server release feature a concept called Release Groups. Just as the name suggests, it groups several releases together in one entity. Since this is not obviously clear, this page explains the difference and gives some guidelines on how to handle them.

Both release groups and releases are "albums" in colloquial sense, but with a slight difference: a release is something you can buy as media, e.g. a CD box, a vinyl record etc. on its own, while a release group embraces the concept of an album -- it doesn't matter how many CDs or editions/versions it had. When an artist tells you "We've released our new album", he's talking about a release group.

A release group should not consist of:

Musicbrainz automatically considers every release in the database to be part of a release group, even if this group only contains this one release. You don't have to worry about creating release groups, you only ever need to merge them.
