AWS AWSCloudFormation documentation change

Service: AWSCloudFormation · 2026-04-01 · Documentation low

File: AWSCloudFormation/latest/TemplateReference/aws-properties-emr-cluster-cloudwatchlogconfiguration.md

Summary

Updated property descriptions and added detailed documentation including constraints (pattern, min, max) for CloudWatch logging configuration properties in EMR clusters.

Security assessment

The change adds documentation for security-relevant features like log encryption key ARN and specifies input validation patterns. This improves clarity on security configurations but does not indicate a fix for a specific security issue. The addition of the 'EncryptionKeyArn' property description directly documents a security feature for encrypting logs.
