+# What's new in AKS Edge Essentials
+
+AKS Edge Essentials is a lightweight on-premises Kubernetes implementation of Azure Kubernetes Service (AKS) that automates running containerized applications at scale. This article describes the latest features, enhancements, and updates in AKS Edge Essentials releases.
+
+## Release 1.10.868.0 (March 2025)
+
+The following features and improvements were added in this release:
+
+- **Enable secret encryption on AKS Edge Essentials clusters with the Key Management Service (KMS) plugin (preview)**. Following Kubernetes best practices, it's recommended that you encrypt the Kubernetes secret store on clusters. You can enable the KMS plugin in the **aks-edge** config file during deployment. The KMS plugin is set to **disabled** by default during the preview period. For more information about this feature, see the [Key Management Service (KMS) plugin (preview)](aks-edge-howto-secret-encryption.md) documentation.
+- **Key Manager for Kubernetes on AKS Edge Essentials (preview)**. [Key manager for Kubernetes](aks-edge-howto-key-manager.md) is an Azure Arc extension that automates the rotation of the signing key used to issue service account tokens. For more information about the Key Manager extension, see [Key manager for Kubernetes](aks-edge-howto-key-manager.md).
+- **AKS Edge Essentials now connects to Azure Arc during deployment to decrease the number of required deployment steps.** Arc parameters are now required in the **aks-edge** configuration file during deployment. Starting with the next release, the AKS Edge Essentials deployment will be blocked if Arc parameters are missing or invalid.
+- **The Calico CNI + K3s preview has been discontinued**. You must now use Flannel with K3s and Calico with K8s. For more information, see [Single machine deployment](aks-edge-howto-single-node-deployment.md#step-1-single-machine-configuration-parameters).
