 - [21163](https://github.com/apache/superset/pull/21163): The time grain will be decoupled from the time filter column and the time grain control will move below the X-Axis control when `GENERIC_CHART_AXES` feature flags set to `True`. The time grain will be applied on the time column in the column-like controls(x axis, dimensions) instead of the time column in the time section.
 - [21284](https://github.com/apache/superset/pull/21284): The non-functional `MAX_TABLE_NAMES` config key has been removed.
 - [21794](https://github.com/apache/superset/pull/21794): Deprecates the undocumented `PRESTO_SPLIT_VIEWS_FROM_TABLES` feature flag. Now for Presto, like other engines, only physical tables are treated as tables.
+- [23890](https://github.com/apache/superset/pull/23890): Removes Python 3.8 support.
