+# Attention!
+
+Notable changes in this release:
+- The `chrony` daemon on a Linux node may fail to restart with error message: `"Could not open /dev/ptp_hyperv: No such file or directory"`.
+The workaround for this issue is to manually reboot the affected Linux nodes.
+This operation will regenerate the `/dev/ptp_hyperv` symlink and allow the chrony daemon to restart successfully.
+
+- The control-plane nodes' taint has been changed from node-role.kubernetes.io/master to node-role.kubernetes.io/control-plane, requiring users to update tolerations in their applications to schedule pods on these nodes. Example:
+
+
+```
+tolerations:
+- key: node-role.kubernetes.io/control-plane
+  operator: "Exists"
+  effect: NoSchedule
+
+```
+- Use the new AzureDisk CSI Driver v1.29.1 for k8s v1.28+. Use AzureDisk CSI Driver v1.28.3 for k8s v1.27. Use AzureDisk CSI Driver v1.26.5 for k8s v1.26.
+  - See [Azure Disk CSI Driver: Version Mapping](../docs/topics/azure-stack.md#azure-disk-csi-driver-version-mapping) for more details.
