-_Maintenance window_ – There is no maintenance window with Amazon Redshift Serverless. Software version updates are automatically applied. There's no interruption for existing connection or query execution when Amazon Redshift switches versions. New connections will always connect and work with Amazon Redshift Serverless instantly.
+_Maintenance Window_ – Amazon Redshift Serverless offers automatic software updates without requiring traditional maintenance windows. When a new update is available, the system applies it within 14 days of release during idle periods. The update process typically takes up to 15 minutes. If no 15-minute idle period occurs within 14 days, your Serverless endpoint may experience brief unavailability. During this time, application connections to endpoints may fail. You can monitor Redshift patch releases in the "Cluster versions for Amazon Redshift" documentation. For information about Amazon Redshift Serverless SLAs, see [Amazon Redshift Service Level Agreement](https://aws.amazon.com/redshift/sla/).
