In earlier versions, to create pods in a new zone, you must first add new pod vSwitches in the zone. You can add pod vSwitches in Terway ConfigMaps. When you change the specifications of a node, the maximum number of pods that are supported by Terway on the node also changes. After this release, the K8s max-pod parameter is automatically adjusted to fit the new node specifications.	All regions	Use the Terway plug-in
Node pool management	Node pool management is supported. A node pool contains a group of nodes with the same configurations. For example, nodes in a node pool are configured with the same container runtime, OS, and security group. You can create multiple node pools for a cluster. This allows you to deploy a variety of services to different node pools in a cluster. Node pools also support auto scaling. Nodes can be automatically added when a node pool is short of required resources.	All regions	Manage node pools

New region	Managed Kubernetes clusters are available in the China South 1 Finance region on Alibaba Finance Cloud.	China South 1 Finance	Create a managed Kubernetes cluster
ephemeral-storage	The ephemeral-storage parameter is added for container configurations when you create an application. Ephemeral storage is a new storage resource similar to CPU and memory. Kubernetes uses this parameter to manage and schedule the transient storage of applications that run in Kubernetes clusters. The root directory and log directories (/var/log) of kubelet are stored on the primary partition of a node. In addition, emptyDir volumes, container log, image layers, and the writable layers of containers are also stored on the primary partition. Therefore, ephemeral-storage is used to manage the primary partition of a node. You can set requests and limits when you create an application. This allows you to schedule and manage the storage resources that are allocated from the primary partition to the application.	All regions	Create a stateless application by using a Deployment

Node maintenance	Node maintenance is supported. To maintain nodes in a cluster, you must make sure that workloads are not deployed on the nodes that you want to maintain. ACK supports node maintenance. You can select one or more nodes that you want to maintain and set them to unschedulable on the Nodes page. You can also drain these nodes. After you set a node to unschedulable, pods cannot be scheduled to the node. If you drain a node, no new pods are scheduled to the nodes and existing pods on the node are migrated to other nodes. However, pods that are managed by DaemonSets are not migrated from the node. If you have a LoadBalancer Service, you can specify whether to remove nodes that run the pods that are associated with the Service from the backend of the related SLB instance when these nodes are set to unschedulable. This allows you to flexibly manage your workloads during node maintenance.	All regions	Set node schedulability
Custom node name	Custom node names are supported. To manage a cluster that includes a large number of nodes, you must identify nodes by name. The default node names provided by ACK are not easy to identify. ACK allows you to customize node names when you create a cluster. When you create a cluster in the ACK console, you can select Custom Node Name in the advanced settings of the cluster. You can define a prefix, an IP substring length, and a suffix for a custom node name. The IP substring length specifies the number of digits to be truncated from the end of a node IP address and can be used to uniquely identify a node.	All regions	Create a dedicated Kubernetes cluster

Cloud controller manager	The cloud controller manager is upgraded. The cloud controller manager is the core component in an ACK cluster and is responsible for managing various cloud resources, such as SLB instances and VPCs. The following features are added to the cloud controller manager: SLB instances can be created with access control settings. You can specify an IP whitelist for an SLB instance that is created by ACK. This enhances the security of the ACK cluster. You can specify whether to remove unschedulable nodes when you run the kubectl cordon or kubectl drain command. Cordoning and draining nodes are important features in cluster maintenance. However, the community has not reached an agreement on whether to remove a node from the backend of an SLB instance when the node is set to unschedulable for maintenance. The cloud controller manager provides an interface that allows you to specify whether to remove such nodes from the backend of the SLB instance. This ensures the flexibility of maintenance. Pods can be mounted to the backend of an SLB instance by using Terway. Terway ENI is the latest network plug-in that is provided by ACK. The core feature of Terway ENI is to mount the ENI IP address of a node to a pod. The cloud controller manager allows you to mount pods instead of nodes to the backend of an SLB instance. This prevents traffic forwarding through nodes and improves network performance. Node weights can be set based on the number of pods on each node for Services in Local mode. The cloud controller manager can adjust the percentage of traffic that is sent to each node based on the number of pods on each node. This balances workloads among nodes. This feature applies to only Services in Local mode.	All regions	Cloud Controller Manager
