 # dbt-utils v0.6.0 (unreleased)
 
+## Breaking changes
+- :rotating_light: dbt v0.18.0 or greater is required for this release. If you are not ready to upgrade, consider using a previous release of this package
+- :rotating_light: The `get_tables_by_prefix`, `union_tables` and `get_tables_by_pattern` macros have been removed
+
+## Migration instructions
+- Upgrade your dbt project to v0.18.0 using [these instructions](https://discourse.getdbt.com/t/prerelease-v0-18-0-marian-anderson/1545).
+- Upgrade your `dbt_project.yml` file to use version `0.7.0`. Run `dbt clean` and `dbt deps`.
+- If your project uses the `get_tables_by_prefix` macro, replace it with `get_relations_by_prefix`. All arguments have retained the same name.
+- If your project uses the `union_tables` macro, replace it with `union_relations`. While the order of arguments has stayed consistent, the `tables` argument has been renamed to `relations`. Further, the default value for the `source_column_name` argument has changed from `'_dbt_source_table'` to `'_dbt_source_relation'` — you may want to explicitly define this argument to avoid breaking changes.

+- If your project uses the `get_tables_by_pattern` macro, replace it with `get_tables_by_pattern_sql` — all arguments are consistent.
