File: m2/latest/userguide/m2sftp.md

Summary

Updated service availability notice to announce closure of new customer access to AWS Mainframe Modernization self-managed experience effective July 30, 2026, and added that AWS will continue security and availability improvements for self-managed experience without new features.

Security assessment

General mention of security improvements doesn't indicate resolution of a specific security issue. The change focuses on service lifecycle updates rather than security documentation.
