# 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 to support
having a Document Set intermediary. [See here](../migration/document-sets.md) for an example build task to help with
this process.

## Template changes

The default template entry point is now `DocumentSets.ss` (previously `Documents.ss`). As well as this change,
`Documents.ss` has been renamed to `DocumentSet.ss`.

## Frontend assets

We've removed the configuration for using Compass to build SCSS. You can now use Webpack instead.
[See here](building-frontend-assets.md) for more information on this.
