Changelog since v1.14.0

Action Required

• client-go: The rest.AnonymousClientConfig(*rest.Config) *rest.Config helper method no longer copies custom Transport and WrapTransport fields, because those can be used to inject user credentials. (#75771, @liggitt)
• ACTION REQUIRED: The Node.Status.Volumes.Attached.DevicePath field is now unset for CSI volumes. Update any external controllers that depend on this field. (#75799, @msau42)

Other notable changes

• Remove the function Parallelize, please convert to use the function ParallelizeUntil. (#76595, @danielqsj)
• StorageObjectInUseProtection admission plugin is additionally enabled by default. (#74610, @oomichi)
  • So default enabled admission plugins are now NamespaceLifecycle,LimitRanger,ServiceAccount,PersistentVolumeLabel,DefaultStorageClass,DefaultTolerationSeconds,MutatingAdmissionWebhook,ValidatingAdmissionWebhook,ResourceQuota,StorageObjectInUseProtection. Please note that if you previously had not set the --admission-control flag, your cluster behavior may change (to be more standard).

• kube-proxy no longer automatically cleans up network rules created by running kube-proxy in other modes.
