# 2.0.0 (unreleased)

## Document sets

Documents now belong to "sets", which are attached to Pages. A Page can have many Document Sets, and a Set has a
many_many relationship with Documents.

When upgrading from 1.x to 2.x you will need to migrate the relationships from your Pages to Documents so support
having a Document Set intermediary (@todo Add a build task for this).
