 ## 1.37.0 (Unreleased)
 
+NOTES
+
+The `azurerm_kubernetes_cluster` resource has undergone substantial changes in this release to work around breaking behavioural changes in the Azure API. As such the `agent_pool_profile` block has been superseded by the `default_node_pool` block. Multiple Node Pools can instead be configured using the (upcoming) `azurerm_kubernetes_cluster_node_pool` resource.
