 - [20799](https://github.com/apache/superset/pull/20799): Presto and Trino engine will now display tracking URL for running queries in SQL Lab. If for some reason you don't want to show the tracking URL (for example, when your data warehouse hasn't enable access for to Presto or Trino UI), update `TRACKING_URL_TRANSFORMER` in `config.py` to return `None`.
 - [21002](https://github.com/apache/superset/pull/21002): Support Python 3.10 and bump pandas 1.4 and pyarrow 6.
 - [21163](https://github.com/apache/superset/pull/21163): When `GENERIC_CHART_AXES` feature flags set to `True`, the Time Grain control will move below the X-Axis control.
