AWS opensearch-service documentation change

Service: opensearch-service · 2025-07-16 · Documentation low

File: opensearch-service/latest/developerguide/createupdatedomains.md

Summary

Added steps for IAM Identity Center authentication, Natural Language Query/Amazon Q features, and S3 Vectors engine option. Renumbered subsequent steps.

Security assessment

The change introduces IAM Identity Center authentication as an optional security feature, which enhances access control but does not indicate a security vulnerability fix. Encryption and HTTPS settings remain unchanged (renumbered steps only).
