### Schema Change Detection 🤗

Schema changes catching you by surprise? While the dbt Impact Report helps you prevent unexpected breaking changes, [Schema Change Detection](https://docs.selectstar.com/features/schema-change-detection) gives you visibility when things do change.

Now users can see schema change events, such as table created, columns created or deleted, and column data type changes in your table history.
