### SIG OpenStack

SIG-OpenStack continued to build out testing, with eleven acceptance tests covering a wide-range of scenarios and use-cases. During the 1.11 cycle our reporting back to test-grid has qualified the OpenStack cloud provider as a gating job for the Kubernetes release.

- The Pod API field `.spec.schedulingGates[*].name` now requires qualified names (like `example.com/mygate`), matching validation for names of `.spec.readinessGates[*].name`. Any uses of the alpha scheduling gate feature prior to 1.27 that do not match that validation must be renamed or deleted before upgrading to 1.27....

.io;v=v1beta1` or `application/json;as=PartialObjectMetadata;g=meta.k8s.io;v1=v1beta1`.  Older servers will ignore this representation or return an error if it is not available.  Clients may request fallback to the normal object by adding a non-qualified mime-type to their `Accept` header like `application/json` - the server will then respond with either the alternate representation if it is supported or the fallback mime-type which is the normal object response. ([#59059](https://github.com/kub...

- When specifying `--(kube|system)-reserved-cgroup`, with `--cgroup-driver=systemd`, it is now possible to use the fully qualified cgroupfs name (i.e. `/test-cgroup.slice`). ([#78793](https://github.com/kubernetes/kubernetes/pull/78793), [@mattjmcnaughton](https://github.com/mattjmcnaughton))

- `kubeadm`: will now throw warnings instead of errors for deprecated feature gates. ([#118270](https://github.com/kubernetes/kubernetes/pull/118270), [@pacoxu](https://github.com/pacoxu))
- `kubectl events --for` will also support fully qualified names such as replicasets.apps,
  etc. ([#117034](https://github.com/kubernetes/kubernetes/pull/117034), [@ardaguclu](https://github.com/ardaguclu))

- Added support for CEL(Common Expression Language) expressions and `additionalProperties` to be used under nested quantifiers in CRD schemas. ([#124381](https://github.com/kubernetes/kubernetes/pull/124381), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery]
- Added support for building Windows kube-proxy container image.

 the apps/v1beta1 API in this release, but you should start planning for code
 that does not depend on mutable selectors.

 - Extended Resources are fully-qualified resource names outside the
 `kubernetes.io` domain. Extended Resource quantities must be integers.
 You can specify any resource name of the form `[aaa.]my-domain.bbb/ccc`

  <!-- First Quattro Pro for Windows had major version number 1, which
  was followed by 5. This is confusing, perhaps adding "win" qualifier to version
  field could clear this up (but it's quite ugly as well)   -->
