thanks!

Thanks for letting me know.

I just updated the manifests to use 1.23.5.

The change is in https://github.com/vfarcic/devops-toolkit-crossplane/blob/master/packages/k8s/aks.yaml#L38. Alternatively, you can specify any version through XR definition which, in that demo, is https://github.com/vfarcic/devops-toolkit-crossplane/blob/master/examples/azure-aks.yaml. You can do that by adding spec.parameters.version entry.
