- Resolves spurious `Failed to list *v1.Secret` or `Failed to list *v1.ConfigMap` messages in kubelet logs. ([#99538](https://github.com/kubernetes/kubernetes/pull/99538), [@liggitt](https://github.com/liggitt)) [SIG Auth and Node]

* Fix image file system stats for windows nodes. ([#59743](https://github.com/kubernetes/kubernetes/pull/59743), [@feiskyer](https://github.com/feiskyer))

* Kubernetes will now return an error if New-SmbGlobalMapping failed when mounting an azure file on Windows. ([#59540](https://github.com/kubernetes/kubernetes/pull/59540), [@andyzhangx](https://github.com/andyzhangx))

- kubeadm: Improved `kubeadm init` and `kubeadm join` to provide consistent error messages when the kubelet failed or when failed to wait for control plane components. ([#130040](https://github.com/kubernetes/kubernetes/pull/130040), [@HirazawaUi](https://github.com/HirazawaUi))

- We will no longer automatically delete all data when a failure is detected during creation of the volume data file on a CSI volume. Now we will only remove the data file and volume path. ([#96021](https://github.com/kubernetes/kubernetes/pull/96021), [@huffman...

provisioned PVs, if its volume source is CSI type or it has migrated annotation, when it's deleted, the PersisentVolume controller won't changes its phase to the Failed state. 
  
  With this patch, the external provisioner can remove the finalizer in next reconcile loop. Unfortunately if the provious existing pv has the Failed state, this patch won't take effort. It requires users to remove finalizer. ([#126045](https://github.com/kubernetes/kubernetes/pull/126045), [@carlory](https://...

- kube-proxy: a configuration file specified via `--config` is now loaded with strict deserialization, which fails if the config file contains duplicate or unknown fields. This protects against accidentally running with config files that are malformed, mis-indented, or have typos in field names, and getting unexpected behavior. ([...

* Fixed a regression in kube-scheduler to properly load client connection information from a `--config` file that references a kubeconfig file. ([#65507](https://github.com/kubernetes/kubernetes/pull/65507), [@liggitt](https://github.com/liggitt))
* Fix regression in `v1.JobSpec.backoffLimit` that caused failed Jobs to be restarted indefinitely. ([#63650](https://github.com/kubernetes/kubernetes/pull/63650), [@soltysh](https://github.com/soltysh))

- Remove `NodeLease` feature gate that was graduated and locked to stable in 1.17 release. ([#1052...

  - kubectl create secret docker-registry <NAME> --from-file=.dockerconfigjson=<path/to/.docker/config.json> ([#119589](https://github.com/kubernetes/kubernetes/pull/119589), [@carlory](https://github.com/carlory)) [SIG CLI]

- Give terminal phase correctly to all pods that will not be restarted. 

  In particular, assign Failed phase to pods which are deleted while pending. Also, assign a terminal 
  phase (Succeeded or Failed, depending on the exit statuses of the pod containers) to pods which
  are deleted while running.
