AWS cli documentation change

Service: cli · 2025-08-10 · Documentation low

File: cli/latest/reference/gameliftstreams/start-stream-session.md

Summary

Updated AWS CLI version reference, reordered parameters, added new parameters (client-token, description, identifier, protocol), modified parameter descriptions, and reorganized output fields

Security assessment

The changes primarily reorganize parameters and update descriptions without addressing specific security vulnerabilities. The added client-token parameter documentation describes idempotency which is a reliability feature rather than a security fix. No evidence of patching vulnerabilities or addressing security incidents exists in the diff.
