New! IBM Cloud Kubernetes Service version 1.30.: You can now create or update clusters to Kubernetes version 1.30. With Kubernetes 1.30, you get the latest stable enhancements from the Kubernetes community as well as enhancements to the IBM Cloud product.
IBM Cloud Kubernetes Service version 1.30 Kubernetes certification: IBM Cloud Kubernetes Service version 1.30 is now Kubernetes certified.
Important networking changes for IBM Cloud Kubernetes Service VPC clusters created at version 1.30.: For more information, see the 130 version information and Understanding Secure by Default Cluster VPC Networking.
Important changes to the default cluster provisioning behavior for new VPC clusters beginning with version 1.30.: Beginning with version 1.30, there is a new option available at cluster creation time via the UI, CLI, API, and Terraform. This new option manages outbound traffic protection for the cluster. The default behavior is to have outbound traffic protection enabled, which means new version 1.30 VPC clusters won't have access the public internet by default. If your cluster needs access to the public internet, you must specifically include the option (from the UI, CLI, API, and Terraform) to disable outbound traffic protection. Note that you can also disable outbound traffic protection after your cluster is created. You can also selectively allow outbound traffic as needed after your cluster is created. If you provision clusters via automation, make sure to adjust your automation accordingly.; For more information, see the 1.30 version information, Understanding Secure by Default Cluster VPC Networking, and Managing outbound traffic protection in VPC clusters.
Managing outbound traffic protection in new version 1.30 VPC clusters.: With the introduction of Secure by Default Cluster VPC networking in version 1.30 and later clusters, there are several scenarios where you might need to adjust the security group settings for your clusters to allow outbound traffic to certain resources. For more information, see Managing outbound traffic protection in VPC clusters.

Networking changes for VPC clusters 1.28 and later: In version 1.27 and earlier, VPC clusters pull container images from the IBM Cloud Container Registry through a private cloud service endpoint for the Container Registry. For version 1.28 and later, this network path is updated so that images are pulled through a VPE gateway instead of a private service endpoint. For more information, see the 1.28 change log.
Trusted profile updates for Kubernetes clusters version 1.28 and later.: You can now give trusted profiles service level access to your clusters, then use a federated ID, like App ID, to access the cluster at the level assigned in the trusted profile since trusted profile identities are now synced into the cluster RBAC.

New! Updated GPU drivers with version 1.28 clusters.: With the release of IBM Cloud Kubernetes Version 1.28, GPU drivers moved to the 500 series version for all GPU worker node flavors.
