AWS AmazonS3 documentation change

Service: AmazonS3 · 2025-11-13 · Documentation low

File: AmazonS3/latest/userguide/s3-express-tutorial-endpoints.md

Summary

Updated VPC endpoint creation steps with Local Zone route table specification, added IP address type options (IPv4/IPv6/Dualstack), and optional tagging

Security assessment

Changes focus on network configuration options and documentation clarity. While IP address types relate to network architecture, there is no explicit mention of security vulnerabilities or security feature enhancements.
