- Fix bug where loadbalancer deletion gets stuck because of missing resource group [#75198](https://github.com/kubernetes/kubernetes/issues/75198) ([#93962](https://github.com/kubernetes/kubernetes/pull/93962), [@phiphi282](https://github.com/phiphi282)) [SIG Cloud Provider]

### Bug or Regression

- Fixes a race condition in the iptables mode of kube-proxy in 1.27 and later
  that could result in some updates getting lost (e.g., when a service gets a
  new endpoint, the rules for the new endpoint might not be added until
  much later). ([#122815](https://github.com/kubernetes/kubernetes/pull/122815), [@wedaly](https://github.com/wedaly)) [SIG Network]

`kubeadm init --config /etc/kubeadm/kubeadm.yaml`

([#55479](https://github.com/kubernetes/kubernetes/pull/55479), [@ijc](https://github.com/ijc))

  - This issue can be resolved by restarting docker daemon
- CORS works only in insecure mode ([#24086](https://github.com/kubernetes/kubernetes/issues/24086))
- Persistent volume claims gets added incorrectly after being deleted under stress. Happens very infrequently. ([#26082](https://github.com/kubernetes/kubernetes/issues/26082))

#### Docker runtime Known Issues

## Changelog since v1.12.0

### Other notable changes

* kubeadm now allows mixing of init/cluster and join configuration in a single YAML file (although a warning gets printed in this case).  ([#69426](https://github.com/kubernetes/kubernetes/pull/69426), [@rosti](https://github.com/rosti))

- Fix a bug on the endpoints controller that does not reconcile the Endpoint object after this is truncated (it gets more than 1000 endpoints addresses) ([#127417](https://github.com/kubernetes/kubernetes/pull/127417), [@aojea](https://github.com/aojea)) [SIG Apps, Network and Testing]

    assertThat(readAscii(response.body.byteStream(), Int.MAX_VALUE))
      .isEqualTo("This page has moved!")
    val page1 = server.takeRequest()

*   Added a new --etcd-upgrade keyword to kubeadm upgrade apply. When this keyword is specified, etcd's static pod gets upgraded to the etcd version officially recommended for a target kubernetes release.
