* kubectl: This client version requires the `apps/v1` APIs, so it will not work against a cluster version older than v1.9.0. Note that kubectl only guarantees compatibility with clusters that are +/-1 minor version away. ([#61419](https://github.com/kubernetes/kubernetes/pull/61419), [@enisoc](https://github.com/enisoc))

// An EphemeralContainer is a temporary container that you may add to an existing Pod for
// user-initiated activities such as debugging. Ephemeral containers have no resource or
// scheduling guarantees, and they will not be restarted when they exit or when a Pod is
// removed or restarted. The kubelet may evict a Pod if an ephemeral container causes the
// Pod to exceed its resource allocation.

- The pod phase lifecycle guarantees that terminal Pods, those whose states are `Unready` or `Succeeded`, can not regress and will have all container stopped. Hence, terminal Pods will never be reachable and should not publish their IP addresses on the `Endpoints` or `EndpointSlices`,...

- `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))

- Wait.PollUntilContextTimeout function, if immediate is true, the condition will be invoked before waiting and guarantees that the condition is invoked at least once and then wait a interval before executing again.

SIG OpenStack release is the work-in-progress for removing the in-tree provider. This work, being done in conjunction with SIG Cloud Provider, is focusing on moving internal APIs that the OpenStack (and other providers) depends upon to staging to guarantee API stability. This work also included abstracting the in-tree Cinder API and refactoring code to the external Cinder provider to remove additional Cinder volume provider code.

Additional work was also done to implement an OpenStack...
