AWS AmazonECS documentation change
Summary
Added entry for new IAM permission (ec2:DescribeInstanceEventWindows) to AmazonECSServiceRolePolicy and standardized terminology (changed 'Auto Scaling group' to 'Amazon EC2 Auto Scaling group', 'Elastic Load Balancing' to 'ELB') in multiple entries
Security assessment
The IAM policy update adds a permission required for operational functionality (fetching EC2 Event Windows) but does not indicate a security vulnerability fix. Terminology changes improve consistency but don't address security issues.
