- 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.

  - 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

- Fixed file permission issues that happened during update of Secret/ConfigMap/projected volume when fsGroup is used. The problem caused a race condition where application gets intermittent permission denied error when reading files that were just updated, before the correct permissions were applied. ([#114728](https://github.com/kubernetes/kubernetes/pull/114728), [@furkatgofurov7](https://github.com/furkatgofurov7)) [SIG...

- 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]

### 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]
