  • kubeadm: add optional ECDSA support. (#76390, @rojkov)
    • kubeadm still generates RSA keys when deploying a node, but also accepts ECDSA

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)

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).

  • improve kubectl auth can-i command by warning users when they try access resource out of scope (#76014, @WanLinghao)
  • Introduce API for watch bookmark events. (#74074, @wojtek-t)
    • Introduce Alpha field AllowWatchBookmarks in ListOptions for requesting watch bookmarks from apiserver. The implementation in apiserver is hidden behind feature gate WatchBookmark (currently in Alpha stage).

  • Fix issue in Portworx volume driver causing controller manager to crash (#76341, @harsh-px)
  • kubeadm: Fix a bug where if couple of CRIs are installed a user override of the CRI during join (via kubeadm join --cri-socket ...) is ignored and kubeadm bails out with an error (#76505, @rosti)

  • Fix empty array expansion error in cluster/gce/util.sh (#76111, @kewu1992)
  • kube-proxy no longer automatically cleans up network rules created by running kube-proxy in other modes.

Please convert to use *_admission_duration_seconds and *_admission_duration_seconds_summary, these now report the unit as described, and follow the instrumentation best practices. (#75279, @danielqsj)
