See the full kOps 1.36 release notes for details, including breaking changes and deprecations.

Highlights

• Kubernetes 1.36 support and completion of the move away from the in-tree cloud providers
• Reworked addon management: kops-channels now runs as a static pod on control-plane nodes; the standalone channels binary is no longer distributed
• Hybrid bootstrap for gossip clusters: workers bootstrap directly against the API load balancer, easing migration off gossip DNS, which is deprecated
• Karpenter refresh: Karpenter v1.13.0 with kOps-managed EC2NodeClass and NodePool objects per instance group
• etcd-manager improvements: recovery of members with replaced data disks, membership changes resilient to unreachable members, a distroless image, and faster single-member cluster startup
• Expanded Azure support: cloud-controller-manager, Azure Disk CSI driver, and experimental Terraform target
• Hetzner Cluster Autoscaler support and groundwork for Linode (Akamai) as a new cloud provider
• Component updates: containerd v2.2.4, etcd-manager v3.0.20260707 with etcd 3.5.31/3.6.12, AWS Load Balancer Controller v3.3.0, Cilium tunables, CoreDNS v1.14.2, cluster-autoscaler v1.36.0
• Removed: support for Kubernetes 1.30, etcd 3.4, Amazon Linux 2, Ubuntu 20.04, and Debian 10
