- `wait.PollUntilContextTimeout` function, if immediate is true, the condition
  will be invoked before waiting and guarantees that the condition is invoked at
  least once, regardless of whether the context has been cancelled. ([#118686](https://github.com/kubernetes/kubernetes/pull/118686), [@aojea](https://github.com/aojea))

- In the `wait.PollUntilContextTimeout` function, if `immediate` is true, the condition will now be invoked before waiting, guaranteeing that the condition is invoked at least once and then wait a interval before executing again. ([#119762](https://github.com/kubernetes/kubernetes/pull/119762), [@AxeZhan](https://github.com/AxeZhan))

- `DelayingQueue.ShutDown()` can now be invoked multiple times without causing a closed channel panic. ([#77170](https://github.com/kubernetes/kubernetes/pull/77170), [@smarterclayton](https://github.com/smarterclayton))

- Feature gate `ProbeTerminationGracePeriod` is enabled by default. ([#108541](https://github.com/kubernetes/kubernetes/pull/108541), [@kerthcet](https://github.com/kerthcet))

- When invoked with `-list-images`, the `e2e.test` binary now also lists the images that might be needed for storage tests. ([#108458](https://github.com/kubernetes/kubernetes/pull/108458), [@pohly](https://github.com/pohly))

* kubeadm: Make self-hosting work by using DaemonSets and split it out to a phase that can be invoked via the CLI ([#47435](https://github.com/kubernetes/kubernetes/pull/47435), [@luxas](https://github.com/luxas))

Please consult the installation procedure you are using (kargo, kops, kube-up,
kube-aws, kubeadm etc) for specific advice.

1.6 encourages etcd3, and switching from etcd2 to etcd3 involves a full
migration of data between different storage engines.  You must stop the API
from writing to etcd during an etcd2 -> etcd3 migration.  HA installations cannot

[Pod Priority and Preemption](https://kubernetes.io/docs/concepts/configuration/pod-priority-preemption/) has graduated to Beta, so it is enabled by default. Note that this involves [significant and important changes for operators](https://github.com/kubernetes/sig-release/pull/201/files).
