 #### Features
 
+- [Cluster profile variables](../profiles/cluster-profiles/create-cluster-profiles/define-profile-variables/create-cluster-profile-variables.md)
+  now support the drop-down input type. This improvement allows users to enforce the configuration of cluster profile
+  variables using predefined values only, reducing input errors and enhancing cluster profile validation.
+
 #### Improvements
 
 - When viewing project platform settings in Palette, the
   [Cluster Auto Remediation](../clusters/cluster-management/platform-settings/cluster-auto-remediation.md) settings are
   now correctly labeled as an override to the tenant-level settings.
-- [Cluster profile variables](../profiles/cluster-profiles/create-cluster-profiles/define-profile-variables/create-cluster-profile-variables.md)
-  now support the dropdown input type. This improvement allows users to enforce the configuration of cluster profile
-  variables using predefined values only, reducing input errors and enhancing cluster profile validation.

+- Palette supports encryption at host of your Azure Kubernetes cluster using
+  [End-to-End encryption with platform-managed keys](https://learn.microsoft.com/en-us/azure/virtual-machines/disk-encryption#encryption-at-host---end-to-end-encryption-for-your-vm-data).
+  This ensures that encryption starts on the VM host itself, including temporary disks, operating system (OS), and data
+  disk caches. Refer to the Azure Encryption At Host for Azure IaaS guide for further information.
+
+- Velero has been upgraded to version 1.16, which is used internally by Palette for backing up and restoring clusters.
+  Existing clusters with backups configured will be automatically updated to Velero version 1.16, ensuring continuous
+  access to backup and restore functionality. Refer to the
+  [Backup and Restore](../clusters/cluster-management/backup-restore/backup-restore.md) page to learn more about backup
+  and restore tools in Palette.
+
 - When creating Azure IaaS clusters, you can disable automatic creation of route table entries for pod-to-pod
   communication using the `cloud.cloudControllerManager.configureCloudRoutes` parameter. This improvement is useful when
   using Calico or Cilium Container Network Interfaces (CNIs), which support pod networking across nodes by default
   without requiring these route tables and entries. Refer to the
   [Create and Manage Azure IaaS Cluster](../clusters/public-cloud/azure/create-azure-cluster.md#deploy-an-azure-cluster)
   guide for more information.

+- [Palette Management Appliance](../enterprise-version/install-palette/palette-management-appliance.md) and
+  [VerteX Management Appliance](../vertex/install-palette-vertex/vertex-management-appliance.md) now automatically
+  delete the `provider_extract` directory after deployment, removing unused files. Additionally, Palette and VerteX
+  management appliance now use <VersionedLink text="Palette eXtended Kubernetes Edge (PXK-E)" url="/integrations/packs/?pack=edge-k8s" /> 1.32.8 and <VersionedLink text="Piraeus Operator" url="/integrations/packs/?pack=piraeus-operator" /> 2.9.0 internally.

+#### Bug Fixes
+
+- Fixed an issue that prevented the
+  [Virtual Machine Migration Assistant](../vm-management/vm-migration-assistant/vm-migration-assistant.md) from
+  successfully upgrading several resources in the `konveyor-forklift` namespace.
+
+- Fixed an issue that caused a public NAT gateway to be incorrectly provisioned for
+  [Azure IaaS clusters](../clusters/public-cloud/azure/create-azure-cluster.md) configured to use private networks.
+
+- Fixed an issue that prevented the [Azure Service Operator (ASO)](https://azure.github.io/azure-service-operator/) from
+  attaching the worker pool subnet to the NAT Gateway for
+  [Azure IaaS clusters](../clusters/public-cloud/azure/create-azure-cluster.md) using static placement.
