 ### Announcements
 * Ubuntu version updates
   * Ubuntu 24.04 is now generally available and will be the default for OS SKU `Ubuntu` starting in Kubernetes v1.35. This means that if you upgrade to Kubernetes v1.35 with `Ubuntu` OS SKU, you'll automatically update your OS version from Ubuntu 22.04 to Ubuntu 24.04. If you'd like to continue to use Ubuntu 22.04, you can use it until Kubernetes v1.36 end of life. You can also create or update your existing node pools using CLI version 2.82.0+. For more information, see [documentation](https://aka.ms/aks/upgrade-os-version).
-  * Ubuntu 18.04 support has been removed from AKS, meaning you'll no longer be able to scale your node pools. If you are currently using Ubuntu 18.04 on AKS, please follow our instructions to [upgrade](https://learn.microsoft.com/en-us/azure/aks/upgrade-aks-cluster) your Kubernetes version to 1.25+ where Ubuntu 22.04 will be the default Ubuntu version. For more information on this retirement and removal, see [AKS Github Issues](https://github.com/Azure/AKS/issues/4873)

 * Since November 30, 2025, Azure Kubernetes Service (AKS) no longer supports or provides security updates for Azure Linux 2.0. The Azure Linux 2.0 node image is frozen at the [202512.06.0 release](vhd-notes/AzureLinux/202512.06.0.txt). Beginning March 31, 2026, node images will be removed, and you'll be unable to scale your node pools.  Migrate to a supported Azure Linux version by [upgrading your node pools](https://learn.microsoft.com/azure/aks/upgrade-cluster?tabs=azure-cli) to a supported Kubernetes version or migrating to [osSku AzureLinux3](https://learn.microsoft.com/azure/aks/upgrade-os-version).
