 - Now uses `print` instead of `log` to output the generated text into the console. This enables you to invoke dbt with the `--quiet` flag and directly pipe the codegen output into a new file, ending up with valid yaml

 # dbt-codegen v0.7.0
 
 ## 🚨 Breaking change
+
 - Add support for including description placeholders for the source and table, which changes the behavior of `generate_source` when `include_descriptions` is set to `True`. Previous logic only created description placeholders for the columns ([#64](https://github.com/dbt-labs/dbt-codegen/issues/64), [#66](https://github.com/dbt-labs/dbt-codegen/pull/66))
 
 ## New features

 - Add optional `table_names` arg to `generate_source` ([#50](https://github.com/dbt-labs/dbt-codegen/issues/50), [#51](https://github.com/dbt-labs/dbt-codegen/pull/51))
 - Add support for importing descriptions from columns with the same names in upstream models. It is available by setting the parameter `upstream_descriptions` to `True` in `generate_model_yaml` ([#61](https://github.com/dbt-labs/dbt-codegen/pull/61))
 - Added `case_sensitive_cols` argument to `generate_base_model` macro ([#63](https://github.com/dbt-labs/dbt-codegen/pull/63))
