### SIG Storage

- The AllowedTopologies field inside StorageClass is now validated against set and map semantics. Specifically, there cannot be duplicate TopologySelectorTerms, MatchLabelExpressions keys, or TopologySelectorLabelRequirement Values. ([#66843](https://github.com/kubernetes/kubernetes/pull/66843), [@verult](https://github.com/verult))

	c.Assert(err, nil)
	// execute the HTTP request.
	response3, err := s.client.Do(request)
	c.Assert(err, nil)
	c.Assert(response3.StatusCode, http.StatusOK)

	// The reason to duplicate this structure here is to verify if the
	// unmarshalling works from a client perspective, specifically
	// while unmarshalling time.Time type for 'Initiated' field.

        )
        self.middleware_stack: Union[ASGIApp, None] = None
        self.setup()

    def build_middleware_stack(self) -> ASGIApp:
        # Duplicate/override from Starlette to add AsyncExitStackMiddleware
        # inside of ExceptionMiddleware, inside of custom user middlewares

equations for the respective type parameters.

For example, given

<pre>
// dedup returns a copy of the argument slice with any duplicate entries removed.
func dedup[S ~[]E, E comparable](S) S { … }

type Slice []int
var s Slice
s = dedup(s)   // same as s = dedup[Slice, int](s)
</pre>

- EndpointSlice controllers are less likely to create duplicate EndpointSlices. ([#100103](https://github.com/kubernetes/kubernetes/pull/100103), [@robscott](https://github.com/robscott)) [SIG Apps and Network]

- Improvements were made to `kubeadm reset` related to cleaning  etcd and notifying the user about the state of iptables.
- kubeadm commands now print warnings if input YAML documents contain unknown or duplicate fields.
- kubeadm now properly recognizes Docker 18.09.0 and newer, but still treats 18.06 as the default supported version.
- kubeadm now automatically sets the `--pod-infra-container-image` flag when starting the kubelet.

- Fixed a regression in default 1.26 configurations, which enabled PodDisruptionConditions by default, 
  that prevented the control plane's pod garbage collector from deleting pods that contained duplicated field keys (env. variables with repeated keys or container ports).

* Bumps metrics-server version to v0.3.6 with following bugfix: ([#83907](https://github.com/kubernetes/kubernetes/pull/83907), [@olagacek](https://github.com/olagacek))
        *  Don't break metric storage when duplicate pod metrics encountered causing hpa to fail
* kube-apiserver: Fixed a regression accepting patch requests > 1MB ([#84963](https://github.com/kubernetes/kubernetes/pull/84963), [@liggitt](https://github.com/liggitt))

- Remove the deprecated flag `--generator` from `kubectl create deployment` command. ([#99915](https://github.com/kubernetes/kubernetes/pull/99915), [@BLasan](https://github.com/BLasan))
- Remove the duplicate packet import. ([#101187](https://github.com/kubernetes/kubernetes/pull/101187), [@chuntaochen](https://github.com/chuntaochen))
