Change in AWS CloudTrail Event Formats

On July 5, 2021, CloudTrail will update its formatting of numbers contained within the unstructured fields of data events to make it consistent with management events. This change affects four unstructured fields: requestParameter, responseElement, additionalEventData, and serviceEventDetail. 

Sumo Logic is in the process of checking if these changes affect existing Sumo Logic applications and CSE rules and will be completing validation and providing updated artifacts that will support both old and new formats if needed before the deprecation date.
