AWS VPC Container Networking Interface (CNI) Plugin version 1.5 is now the default CNI for new Kubernetes clusters launched by Amazon EKS.
Version 1.5 of the AW VPC CNI plugin improves the behavior of the WARM_IP_TARGET parameter so that any IPs not assigned to pods will be returned back to the subnet. This lowers overall IP address utilization across the cluster. Additionally, a number of bug fixes improve the overall reliability and performance of the CNI for Amazon EKS clusters.
