The new release of Kubernetes 1.5.0 brings several key improvements, including beta support for StatefulSets, enhanced Federation Support, and the introduction of a new command, kubefed. The release also includes significant updates to DaemonSets, Deployments, ConfigMaps, and the kubelet API. Additionally, the installation process has been updated to download smaller binaries, which was causing issues with older versions of Kubernetes. This change requires users to accept a default value when prompted during the cluster creation process. The new release provides improved support for Windows Server Container runtime and CRI for pluggable container runtimes. Furthermore, the kubeadm tool has been updated with improvements to HA setup for master nodes, node robustness, and extensibility. Users can now create a Kubernetes cluster on AWS more seamlessly, but may need to hit enter a few times to accept the default value during the cluster creation process. The release also marks the deprecation of the kube-up.sh script in favor of using Kubernetes Cluster on Amazon using Kops.
