+- [24982](https://github.com/apache/superset/pull/24982): By default, physical datasets on Oracle-like dialects like Snowflake will now use denormalized column names. However, existing datasets won't be affected. To change this behavior, the "Advanced" section on the dataset modal has a "Normalize column names" flag which can be changed to change this behavior.

 ## 2.1.0
 
 - [22809](https://github.com/apache/superset/pull/22809): Migrated endpoint `/superset/sql_json` and `/superset/results/` to `/api/v1/sqllab/execute/` and `/api/v1/sqllab/results/` respectively. Corresponding permissions are `can sql_json on Superset` to `can execute on SQLLab`, `can results on Superset` to `can results on SQLLab`. Make sure you add/replace the necessary permissions on any custom roles you may have.
