Breaking Changes

• Browse Paths have been upgraded to a new format to align more closely with the intention of the feature. Learn more about the changes, including steps on upgrading, here: https://datahubproject.io/docs/advanced/browse-paths-upgrade
• The dbt ingestion source's disable_dbt_node_creation and load_schema options have been removed. They were no longer necessary due to the recently added sibling entities functionality.
• The snowflake source now uses newer faster implementation (earlier snowflake-beta). Config properties provision_role and check_role_grants are not supported. Older snowflake and snowflake-usage are available as snowflake-legacy and snowflake-usage-legacy sources respectively.
