AKS defines a generally available version as a version enabled in all SLO or SLA measurements and available in all regions. AKS supports three GA minor versions of Kubernetes:

  • The latest GA minor version released in AKS.
  • Two previous minor versions.

AKS also offers a limited Platform Support to the N-3 release, where N is the latest GA release. In Platform Support, the AKS Platform remains supported, but scenarios related to Kubernetes functionality and components (including security fixes) aren’t supported

Long Term Support releases receive support and security updates for two years (instead of the usual one year). Due to reliance on the upstream Kubernetes Community for component updates, several addons and features aren’t supported in LTS Support beyond one year. This currently includes: Istio, Calico, Keda, KMS, Dapr, Application Gateway Ingress Controller, Open Service Mesh, and AAD Pod Identity.

More information is available on the Azure Kubernetes Service website.

You can check the version that you are currently using by running:
az aks show --resource-group myResourceGroup --name myAKSCluster
