* Fixes issue where you could not mount NFS or glusterFS volumes using hostnames on GCI/GKE with COS images. ([#42376](https://github.com/kubernetes/kubernetes/pull/42376), [@jingxu97](https://github.com/jingxu97))

  - Health check (liveness & readiness) probes using an HTTPGetAction will no longer follow redirects to different hostnames from the original probe request. Instead, these non-local redirects will be treated as a Success (the documented behavior). In this case an event with reason "ProbeWarning" will be generated, indicating that the redirect was ignored. If you were...

### SIG Cloud Provider

- The cloudstack cloud provider now reports a `Hostname` address type for nodes based on the `local-hostname` metadata key. ([#67719](https://github.com/kubernetes/kubernetes/pull/67719), [@liggitt](https://github.com/liggitt))

### Service
* The 'endpoints.beta.kubernetes.io/hostnames-map' annotation is no longer supported.  Users can use the 'Endpoints.subsets[].addresses[].hostname' field instead. ([#39284](https://github.com/kubernetes/kubernetes/pull/39284), [@bowei](https://github.com/bowei))

### StatefulSet

* GZip openapi schema if accepted by client ([#48151](https://github.com/kubernetes/kubernetes/pull/48151), [@apelisse](https://github.com/apelisse))
* Fixes issue where you could not mount NFS or glusterFS volumes using hostnames on GCI/GKE with COS images. ([#42376](https://github.com/kubernetes/kubernetes/pull/42376), [@jingxu97](https://github.com/jingxu97))

* Webhook client credentials configured with `--admission-control-config-file` must include non-default ports in the configured hostnames. For example, a webhook configured to speak to port 8443 on service `mysvc` in namespace `myns` would specify client credentials in a stanza with `name: mysvc.myns.svc:8443`. See https://kubernetes.io/docs/reference/access-authn-authz/extensible...

* kube-apiserver: The external hostname no longer longer use the cloud provider API to select a default. It can be set explicitly using --external-hostname, if needed. If there is no default, AdvertiseAddress or os.Hostname() will be used, in that order. ([#56812](https://github.com/kubernetes/kubernetes/pull/56812), [@dims](https://github.com/dims))

- Corrected family type (inet6) for ipsets in ipv6-only clusters ([#68436](https://github.com/kubernetes/kubernetes/pull/68436), [@uablrek](https://github.com/uablrek))
- kube-proxy argument `hostname-override` can be used to override hostname defined in the configuration file ([#69340](https://github.com/kubernetes/kubernetes/pull/69340), [@stevesloka](https://github.com/stevesloka))
