no issue
- drops the `var Foo = Ember.Thing.extend({}); export default Foo;` syntax in favour of exporting directly, eg: `export default Ember.Thing.extend({})`
- discussion on this change [here](https://github.com/TryGhost/Ghost/pull/5340#issuecomment-105828423) and [here](https://github.com/TryGhost/Ghost/pull/5694#discussion-diff-37511606)

// roles: DS.hasMany('role', { embedded: 'always' }) => ?include=roles
