@@ -130,6 +130,12 @@ With this configuration the provisioner creates:
 * One PV with StorageClass `local-ssd` for every subdirectory in *_/mnt/local-storage/ssd_*.
 * One PV with StorageClass `local-hdd` for every subdirectory in *_/mnt/local-storage/hdd_*.
 
+The `LocalPersistentVolumes` alpha feature now also requires the `VolumeScheduling` alpha feature. This is a breaking change, and the following changes are required:
+
+* The `VolumeScheduling` feature gate must also be enabled on kube-scheduler and kube-controller-manager components.
+* The `NoVolumeNodeConflict` predicate has been removed. For non-default schedulers, update your scheduler policy.
+* The `CheckVolumeBinding` predicate must be enabled in non-default schedulers.
