AWS AWSCloudFormation documentation change
Summary
Updated documentation links to point to TemplateReference instead of UserGuide, fixed intrinsic function references (e.g., 'Rev' to 'Ref'), added intrinsic function reference links, and added PDF anchor link. General documentation improvements for accuracy and clarity.
Security assessment
Changes involve documentation corrections, URL updates, and typo fixes. No evidence of addressing a specific security vulnerability or introducing security-related content. The 'DependsOn' clarification helps prevent deployment misconfigurations but does not directly mitigate a security issue.
