AWS AWSCloudFormation documentation change
Summary
Updated change set limitations description to include pre-deployment validation coverage and added note about express mode support.
Security assessment
The clarification about validation checks improves accuracy but doesn't reference any security fixes. Express mode documentation doesn't introduce security features or address vulnerabilities.
