 # Azure Kubernetes Service Changelog
 
+## Release 2021-12-9
+
+This release is rolling out to all regions - estimated time for completed roll out is 2021-12-20 for public cloud and 2021-12-23 for sovereign clouds.
+
+### Announcement
+
+* From Kubernetes 1.23, containerD will be the default container runtime for Windows node pools. Docker support will be deprecated in Kubernetes 1.24. You are advised to test your workloads before Docker deprecation happens by following the documentation here https://docs.microsoft.com/en-us/azure/aks/windows-container-cli#add-a-windows-server-node-pool-with-containerd-preview.
+* Konnectivity rollout has been halted for the rest of the year. We will continue the rollout in the new calendar year.
+* AKS is implementing auto-cert rotation slowly over the next few months. We have already enabled the following regions westcentralus, uksouth, eastus, australiacentral, and australiaest. If you have clusters in those regions please run a cluster upgrade in order to have that cluster configured for auto-cert rotation. The following regions brazilsouth, canadacentral, centralindia, and eastasia will be released in January after the holidays as the next group of regions. We will update the release notes will the upcoming schedule going forward until all regions are deployed.
+* Kubernetes 1.19 will be removed on 2021-01-31.
+* Starting with 1.23 AKS will follow upstream kubernetes and deprecate in-tree azure authentication which is marked for deprecation to be replaced with 'exec'. If you are using Azure CLI or Azure clients, AKS will download kubelogin for users automatically. If outside of Azure CLI, users need to download and install kubelogin in order to continue to use kubectl with AAD authentication. <https://github.com/Azure/kubelogin>
