AWS AWSCloudFormation documentation change

Service: AWSCloudFormation · 2026-05-16 · Documentation low

File: AWSCloudFormation/latest/TemplateReference/aws-properties-ecs-service-deploymentlifecyclehook.md

Summary

Added TimeoutConfiguration property, made RoleArn optional, and expanded allowed values for Type property

Security assessment

The changes introduce a new timeout configuration and modify property requirements but contain no evidence of addressing security vulnerabilities. The RoleArn change reduces configuration rigidity without security implications.
