Announcements

• AKS version 1.30 is now available as a Long term support version and AKS version 1.28 End of Life is Jan, 15 2025.
• Upgrade from LTS 1.27 to LTS 1.30 is now supported.
• AKS will be upgrading the KEDA addon to more recent KEDA versions. The AKS team has added KEDA 2.15 on AKS clusters with K8s versions >=1.31, KEDA 2.14 for Kubernetes v1.30. KEDA 2.15 and KEDA 2.14 will introduce multiple breaking changes. View the troubleshooting guide to learn how to mitigate these breaking changes.
• AKS will no longer support the GPU image (preview) to provision GPU-enabled AKS nodes. Starting on Jan 10, 2025 you will no longer be able to create new GPU-enabled node pools with the GPU image. Alternative options that are supported today and recommended by AKS include the default experience with manual NVIDIA device plugin installation or the NVIDIA GPU Operator, detailed in AKS GPU node pool documentation.
• Starting on January 1, 2025, invalid values sent to the Azure AKS API for the properties.mode field of AKS AgentPools will be rejected. Prior to this change, unknown modes were assumed to be User. The only valid values for this field are the (case-sensitive) strings:"User", "System", or "Gateway".
