AWS cli documentation change

Service: cli · 2026-03-28 · Documentation low

File: cli/latest/reference/emr/create-cluster.md

Summary

Updated AWS CLI version reference from 2.34.16 to 2.34.19 and added documentation for new parameter --step-execution-role-arn

Security assessment

The change adds documentation for a new IAM role parameter (--step-execution-role-arn) that allows specifying a role for step execution, which is a security feature for granular permissions. However, there is no evidence of a security issue being fixed.
