## Breaking Changes & Deprecations
- Breaking changes - Added a new dbt_project.yml version format. This emits a deprecation warning currently, but support for the existing version will be removed in a future dbt version ([#2300](https://github.com/fishtown-analytics/dbt/issues/2300), [#2312](https://github.com/fishtown-analytics/dbt/pull/2312)) - The `graph` object available in some dbt contexts now has an additional member `sources` (along side the existing `nodes`). Sources have been removed from `nodes` and added to `sources` instead ([#2312](https://github.com/fishtown-analytics/dbt/pull/2312))
