- Scrub secrets coming from `CommandError`s so they don't get exposed in logs. ([#4138](https://github.com/dbt-labs/dbt-core/pull/4138))
- Syntax fix in `alter_relation_add_remove_columns` if only removing columns in `on_schema_change: sync_all_columns` ([#4147](https://github.com/dbt-labs/dbt-core/issues/4147))
