- `k8s.io/dynamic-resource-allocation/controller:` `UnsuitableNodes` can now handle a mix of allocated and unallocated claims correctly. ([#120338](https://github.com/kubernetes/kubernetes/pull/120338), [@pohly](https://github.com/pohly))

- Dynamic resource allocation: when a claim uses "wait for first consumer" allocation (the default), then it will now get deallocated after it was used by a pod. That ensures that the next pod isn't affected by previous scheduling decision and that resources are not kept allocated unless really needed. If keeping a claim allocated is desired, use "immediate allocation." ([#118936](https://github.com/kubernetes/kubernetes/pull/118936), [@pohl...

*   Fix to ignore extended resources that are not registered with kubelet during container resource allocation. ([#53547](https://github.com/kubernetes/kubernetes/pull/53547),[ @jiayingz](https://github.com/jiayingz))


#### **Container Runtime**

      - current number of available IPs per Service CIDR
      - current number of used IPs per Service CIDR
      - total number of allocation per Service CIDR
      - total number of allocation errors per ServiceCIDR ([#104119](https://github.com/kubernetes/kubernetes/pull/104119), [@aojea](https://github.com/aojea))

- `kubectl delete --all-namespaces` is now a recognized flag. ([#73716](https://github.com/kubernetes/kubernetes/pull/73716), [@deads2k](https://github.com/deads2k))

### Cloud Provider

- Fixed a bug that caused PV allocation on non-English vSphere installations to fail  ([#73115](https://github.com/kubernetes/kubernetes/pull/73115), [@alvaroaleman](https://github.com/alvaroaleman))

### Cluster Lifecycle

// 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.
//
// To add an ephemeral container, use the ephemeralcontainers subresource of an existing
// Pod. Ephemeral containers may not be removed or restarted.
