[v0.75.3] - 2023-02-03

Attention!

AKS Engine release v0.75.3, and all future AKS Engine releases on Azure Stack Hub, will be from the new Azure/aks-engine-azurestack repository. As such, all aks-engine commands should be replaced with aks-engine-azurestack. Please create an issue in the new repository if you find any. 

AKS Engine release v0.75.3 on Azure Stack Hub includes a new Ubuntu 20.04-LTS VHD distro to use in either your control plane and/or worker node pools. Starting from this release, Ubuntu 18.04 will no longer be supported. Please refer to the section Upgrading Kubernetes clusters created with the Ubuntu 18.04 Distro for more details. 

Starting from Kubernetes v1.24, only the containerd runtime is supported. Please refer to the section Upgrading Kubernetes clusters created with docker runtime for more details. For AKS Engine release v0.75.3, clusters with Windows nodes on Kubernetes v1.23 can use the Windows base image with Docker runtime. Clusters with Windows nodes on Kubernetes v1.24 can use the Windows base image with Containerd runtime.
