Announcements

  • Support upgrade version skew policy between core node and control plane components from n-2 to n-3 to match related upstream policy change starting Kubernetes version 1.28. AKS docs available here.
  • Starting 1.30 Kubernetes version and 1.27 LTS versions, beta apis will be disabled by default, when you upgrade to them. There will be an option provided to explicitly enable beta apis closer to the 1.30 release.
  • On 15 March 2027, Windows Server 2022 will be retired when Kubernetes 1.34 reaches the end of platform support. You won't be able to create new Windows Server 2022 node pools on Kubernetes 1.35 and above. We encourage you to make the switch before 15 March 2027 to gain the richer benefits of Windows Server 2025 or Windows Server Annual Channel. These new Windows OS versions will be supported on AKS before Windows Server 2022 is retired. For more updates, see our AKS public roadmap.
  • Kubernetes version 1.26 is now removed. Refer to for platform support timeline.
  • In 2020 Docker enacted a Rate Limiting policy for all users. In-order to assist customers with the change, Microsoft worked directly with Docker to prevent users of Microsoft Azure from being impacted. However, beginning on June 30th, 2024, Azure customers will begin to be impacted by this limit. In-order for customers to mitigate the potential effects of this limit. We recommend customers begin to use the Artifact Cache feature within Azure Container Registry or sign up for a Docker Subscription. More information is available here
