AWS greengrass documentation change

Service: greengrass · 2025-11-07 · Documentation medium

Summary

Added version 2.3.0 with TPM 2.0 support for MQTT authorization, expanded OS support, and bug fixes (e.g., local deployments without internet).

Security assessment

The TPM 2.0 support directly adds security documentation for hardware-backed key storage. The 'local deployments no longer need internet access' reduces attack surface but isn't explicitly tied to a security issue.
