* Some field names in the Kubelet's now v1beta1 config API differ from the v1alpha1 API: for example, PodManifestPath is renamed to StaticPodPath, ManifestURL is renamed to StaticPodURL, and ManifestURLHeader is renamed to StaticPodURLHeader. Users should focus on switching to the v1beta1 API. ([#60314](https://github.com/kubernetes/kubernetes/pull/60314), [@mtaufen](https://github.com/mtaufen))

* fixes a memory leak in the kube-controller-manager observed when large numbers of pods with tolerations are created/deleted ([#65339](https://github.com/kubernetes/kubernetes/pull/65339), [@liggitt](https://github.com/liggitt))

`0.24.0`, a new instance of each middleware class would be created when a new middleware was added. That normally was not a problem, unless the middleware class expected to be created only once, with only one instance, that happened in some cases.

- The `TerminationGracePeriodSeconds` on pod specs and container probes should not be negative. Negative values of `TerminationGracePeriodSeconds` will be treated as the value `1s` on the delete path. Immutable field validation will be relaxed in order to update negative values. In a future release, negative values will not be permitted. ([#98866](https://github.com/kubernetes/kubernetes/pull/98866), [@wzshiming](https://github.com/wzshiming))
