* Fix kubelet to correctly umounts mount points for glusterfs when transport endpoint is not connected and nfs when there is a stale file handle ([#58660](https://github.com/kubernetes/kubernetes/pull/58660), [@humblec](https://github.com/humblec))

- Fixes a bug where images pinned by the container runtime can be garbage collected by kubelet. ([#120053](https://github.com/kubernetes/kubernetes/pull/120053), [@ruiwen-zhao](https://github.com/ruiwen-zhao)) [SIG Node]

- Existing PVs are converted to use volume topology if migration is enabled. ([#83394](https://github.com/kubernetes/kubernetes/pull/83394), [@bertinatto](https://github.com/bertinatto))

* Update kube-dns to Version 1.14.8 that includes only small changes to how Prometheus metrics are collected. ([#57918](https://github.com/kubernetes/kubernetes/pull/57918), [@rramkumar1](https://github.com/rramkumar1))

- The `EndpointSlice` API is now GA. The `EndpointSlice` topology field has been removed from the GA API and will be replaced by a new per Endpoint Zone field. If the topology field was previously used, it will be converted into an annotation in the v1 Resource. The `discovery.k8s.io/v1alpha1` API is removed.

* kube-apiserver: the OpenID Connect authenticator can now verify ID Tokens signed with JOSE algorithms other than RS256 through the --oidc-signing-algs flag. ([#58544](https://github.com/kubernetes/kubernetes/pull/58544), [@ericchiang](https://github.com/ericchiang))

- APIService availability related to networking glitches are corrected faster ([#68678](https://github.com/kubernetes/kubernetes/pull/68678), [@deads2k](https://github.com/deads2k))
