Pull request overview
Updates the AKS changelog to document new Node Auto Provisioning (NAP) capabilities and behavioral changes related to Machine API integration, so customers can understand new supported scenarios and upcoming cluster behavior changes.
Changes:
- Added NAP feature notes for custom Linux OS settings and AMD GPU SKU support via
AKSNodeClass. - Added NAP behavioral changes covering label restrictions, Machine API representation, subnet/identity constraints, and upcoming node naming changes.

| * [Azure Linux 3.0 confidential VM (CVM)](https://learn.microsoft.com/azure/aks/use-azure-linux) is now available in preview in Fairfax (US Gov) regions. Register the `AzureLinuxCVMPreview` feature to enable it. | ||
| * [In-place node pool resize](https://learn.microsoft.com/azure/aks/resize-node-pool) is now available in preview. Resize the VM size of an existing VMSS-based node pool in place via `az aks nodepool update --node-vm-size`, without manually creating and migrating to a new node pool. | ||
| * [Mixed SKU autoscaling in virtual machine node pools](https://learn.microsoft.com/azure/aks/virtual-machines-node-pools#cluster-autoscaler-with-virtual-machines-node-pools-preview) is now available in preview. This allows users to select multiple VM sizes in the same node pool using cluster autoscaler with virtual machine node pools. |
| * AKS now allows migration from the `managedNATGatewayV2` outbound type to the `block` and `none` outbound types, supporting [network-isolated cluster](https://learn.microsoft.com/azure/aks/concepts-network-isolated) scenarios. Migration to other outbound types remains blocked. | ||
| * AKS now validates pod CIDR ranges during cluster create and update for kubenet and [Azure CNI Overlay](https://learn.microsoft.com/azure/aks/azure-cni-overlay) clusters. Clusters can no longer be created or updated with a pod CIDR that overlaps with reserved IP ranges (`172.30.0.0/16`, `172.31.0.0/16`), preventing potential in-cluster networking failures. Existing clusters with an overlapping pod CIDR are unaffected. See [CNI prerequisites](https://learn.microsoft.com/azure/aks/concepts-network-cni-overview#prerequisites). | ||
| * AKS now rejects [Calico NPM and Azure NPM](https://learn.microsoft.com/azure/aks/use-network-policies) install and uninstall operations on clusters running Kubernetes versions earlier than 1.30. Requests are rejected at the API level with a descriptive error directing customers to upgrade to a newer supported Kubernetes version before retrying. Existing clusters already using Calico NPM or Azure NPM are unaffected. | ||
| * Use of specific labels for AKS nodes is restricted from being set by users, including `agentpool`, `storageprofile`, `storagetier`, `accelerator`, and labels with a prefix of `kubernetes.azure.com/`. New subscriptions using NAP can no longer set these labels, and existing subscriptions will be restricted on September 30, 2026. For more information, see [Azure Karpenter Provider Issue #1707](https://github.com/Azure/karpenter-provider-azure/issues/1707). |

| * Node Auto Provisioning (NAP) managed clusters will now include a managed machines-mode node pool named `aksmanagedap`. This machine node pool is used to represent each NAP managed virtual machine instance. This node pool can't be deleted by you and will be deleted when you disable NAP. |
Updated Node Auto Provisioning (NAP) features for Linux nodes and GPU support with additional documentation links.
