 ### Potential Downtime
 
+- [26416](https://github.com/apache/superset/pull/26416): adds 2 database indexes to report_execution_log and 1 to report_recipient to improve performance, this may cause downtime on large deployments.
+
 ### Other
 
 - [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.
