Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

Add support for Ubuntu 24.04. Example Terraform configs for all providers are now using Ubuntu 24.04 by default. If you're using the latest Terraform configs with an existing cluster, make sure to bind the operating system/image to the image that you're currently using, otherwise your instances/cluster might get recreated by Terraform. On some providers, machine-controller will use Ubuntu 24.04 if the image is not explicitly specified. (#3302, @SimonTheLeg)
Example Terraform configs for Hetzner are now using cx22 instead of cx21 instance type by default. If you use the latest Terraform configs with an existing cluster, make sure to override the instance type as needed, otherwise your instances/cluster might get recreated by Terraform. (#3370, @kron4eg)
KubeOne is now validating that IP addresses and hostnames provided for control plane nodes and static worker nodes are different. In other words, it's not possible to use the same machine both as a control plane node and a static worker node. This behavior has never been supported by KubeOne; if you want a control plane node that can schedule any pod, you can provision it as a control plane node and remove the control plane taint (node-role.kubernetes.io/control-plane:NoSchedule). (#3334, @kron4eg)
Update Cilium to v1.16.3. This change might affect users that have nodes that are low on capacity (pods or resources wise). The Cilium architecture has been changed so that the Envoy Proxy is not integrated into Cilium, but is a dedicated component/DaemonSet. If you have nodes that are low on capacity, you might encounter issues when trying to start Envoy Proxy pods on those nodes. In this case, you'll need to override the Cilium addon to use the old architecture with Envoy Proxy integrated into Cilium. (#3415, @xmudrii)
kubeone install and kubeone upgrade subcommands are removed. We have deprecated these commands in KubeOne 1.4, and made them hidden in KubeOne 1.5. With this change, we're permanently removing these two commands. kubeone apply should be used instead. (#3349, @mohamed-rafraf)
