consistently deployed across those clusters, and dynamically managed
to ensure that autoscaling can occur optimially in all clusters,
within a set of global constraints on the total number of replicas
permitted across all clusters.  If replicas are not
required in some clusters due to low system load or insufficient quota
or capacity in those clusters, additional replicas are made available

  relevant Job, taking this now-terminated Pod into consideration.
  
  This behavior is limited to Jobs with `.spec.podFailurePolicy` set, and only when those two feature
  gates are both enabled.
  If either of these requirements is not satisfied, the Job controller counts a terminating Pod as an immediate

- 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](https://github.com/kubernetes/kubernetes/pull/75771), [@liggitt](https://github.com/liggitt))

- The `horizontalpodautoscaling` and `clusterrole-aggregation` controllers now assume the `autoscaling/v1` and `rbac.authorization.k8s.io/v1` APIs are available. If you disable those APIs and do not want to run those controllers, exclude them by passing `--controllers=-horizontalpodautoscaling` or `--controllers=-clusterrole-aggregation` to `kube-controller-manager`. ([#117977](https://github.com/kubernetes/kubernetes/pull/117977), [@liggitt](...

- Introduce scheduling.k8s.io/v1alpha1 Workload API to allow for expressing workload-level scheduling requirements and let kube-scheduler act on those.

- Fixes a 1.30.0 regression in openapi descriptions of imagePullSecrets and hostAliases fields to mark the fields used as keys in those lists as either defaulted or required. ([#124694](https://github.com/kubernetes/kubernetes/pull/124694),...

## Major themes

Kubernetes is developed by community members whose work is organized into
[Special Interest Groups](https://github.com/kubernetes/community/blob/master/sig-list.md), which provide the themes that guide their work. For the 1.9 release, these themes included:

### API Machinery

```

- Kubernetes components no longer handle panics, and instead actively crash.  All Kubernetes components should be run by something that actively restarts them. This is true of the default setups, but those with custom environments may need to double-check (#28800, @lavalamp)
- kubelet now defaults to `--cloud-provider=auto-detect`, use `--cloud-provider=''` to preserve previous default of no cloud provider (#28258, @vishh)

 * equality for both keys and values. This may not be the desired behavior for map implementations
 * that use non-standard notions of key equality, such as the entry of a {@code SortedMap} whose
 * comparator is not consistent with {@code equals}.
 *
 * <p>The {@code standard} methods are not guaranteed to be thread-safe, even when all of the
 * methods that they depend on are thread-safe.
