## Breaking Changes & Deprecations
- Breaking Changes - Version 1 schema.yml specs are no longer implemented. Please use the version 2 spec instead ([migration guide](https://docs.getdbt.com/docs/upgrading-from-0-10-to-0-11#section-schema-yml-v2-syntax)) - `{{this}}` is no longer implemented for `on-run-start` and `on-run-end` hooks. Use `{{ target }}` or an [`on-run-end` context variable](https://docs.getdbt.com/reference#schemas) instead ([#1176](https://github.com/fishtown-analytics/dbt/pull/1176), implementing [#878](https://github.com/fishtown-analytics/dbt/issues/878))
- - A number of materialization-specific adapter methods have changed in breaking ways. If you use these adapter methods in your macros or materializations, you may need to update your code accordingly.
