Given the list of all packages, sorted by import path, in each step the first
uninitialized package in the list for which all imported packages (if any) are
already initialized is <a href="#Package_initialization">initialized</a>.
This step is repeated until all packages are initialized.

- Added flag `--include-uninitialized` to `kubectl annotate`, `apply`, `edit-last-applied`,
  `delete`, `describe`, `edit`, `get`, `label,` and `set`. `--include-uninitialized=true` makes
  kubectl commands apply to uninitialized objects, which by default are ignored
  if the names of the objects are not provided. `--all` also makes kubectl
  commands apply to uninitialized objects. See the

* Add flag "--include-uninitialized" to kubectl annotate, apply, edit-last-applied, delete, describe, edit, get, label, set. "--include-uninitialized=true" makes kubectl commands apply to uninitialized objects, which by default are ignored if the names of the objects are not provided. "--all" also makes kubectl commands apply to uninitialized objects. Please see the [initializer](https://kubernetes.io/docs/admin/extensible-admission-controllers/)...

  optional Probe readinessProbe = 11;

  // StartupProbe indicates that the Pod has successfully initialized.
  // If specified, no other probes are executed until this completes successfully.
  // If this probe fails, the Pod will be restarted, just as if the livenessProbe failed.

- Remove deprecated "include-uninitialized" flag. ([#80337](https://github.com/kubernetes/kubernetes/pull/80337), [@draveness](https://github.com/draveness))

- The cloud config for Azure cloud provider can now be initialized from Kubernetes secret azure-cloud-provider in kube-system namespace
    - the secret is a serialized version of `azure.json` file with key cloud-config. And the secret name is azure-cloud-provider.

- Fixed a bug that init containers with `Always` restartPolicy may not terminate gracefully if the pod hasn't initialized yet. ([#125935](https://github.com/kubernetes/kubernetes/pull/125935), [@gjkim42](https://github.com/gjkim42)) [SIG Node and Testing]
- Fixed a bug where `kubectl describe` incorrectly displayed NetworkPolicy port ranges

- Fixed incorrect watch events when a watch is initialized simultanously with a reinitializing watchcache. ([#116436](https://github.com/kubernetes/kubernetes/pull/116436), [@wojtek-t](https://github.com/wojtek-t))

- If Openstack LoadBalancer is not defined in cloud config, the loadbalancer will no longer beis not initialized. any more in openstack. All setups must have some setting under that section for the OpenStack provider. ([#65781](https://github.com/kubernetes/kubernetes/pull/65781), [@zetaab](https://github.com/zetaab))

* If CSINodeInfo and CSIMigration feature flags are active in the cluster, Kubelet will post NotReady until CSINode is initialized with basic volume plugin mechanism information for well-known drivers ([#74835](https://github.com/kubernetes/kubernetes/pull/74835), [@davidz627](https://github.com/davidz627))
