AWS controltower documentation change
Summary
Added documentation for AWS Control Tower's new IPv6 support through dual-stack endpoints and updated release notes structure
Security assessment
The change introduces IPv6 support documentation, which enhances network security by enabling modern IP standards. However, there is no explicit mention of addressing a specific security vulnerability or incident. The reference to PrivateLink and dual-stack endpoints relates to network security best practices but does not indicate a security fix.
