    This impacts Conscrypt when the server's presented certificates form both a trusted-but-unpinned

## Version 5.0.0-alpha.3

_2021-11-22_

release.  A new alpha feature is introduced to improve the mechanism that nodes heartbeat back to the control plane.  The `NodeLease` feature results in the node using a `Lease` resource in the `kube-node-lease` namespace that is renewed periodically.  The `NodeStatus` that was used previously to heartbeat back to the control plane is only updated when it changes.  This reduces load on the control plane for large clusters. The Kubelet plugin registration mechanism, which enables automatic discovery of external...

It could be used to tell kubeadm to wait for all control plane components to be ready when running "kubeadm init" or "kubeadm join --control-plane". Previously, kubeadm only waited for the kube-apiserver. The "kubeadm join" workflow now includes a new experimental phase called "wait-control-plane". This phase was marked as non-experimental when WaitForAllControlPlaneComponents became GA. Accordingly, a "kubeadm init" phase "wait-control-plane" was also available once WaitForAllControlPlaneComponents...

- Kubeadm: only taint control plane nodes when the legacy "master" taint is present. This avoids the bug where "kubeadm upgrade" will re-taint a control plane  node with the new "control plane" taint even if the user explicitly untainted the node. ([#109840](https://github.com/kubernetes/kubernetes/pull/109840), [@neolit123](https://github.com/neolit123))

- Show a warning message to inform users that the `legacy` profile is planned to be deprecated. ([#127230](https://github.com/kubernetes/kubernetes/pull/127230), [@mochizuki875](https://github.com/mochizuki875)) [SIG CLI]

  - The `kubeadm upgrade node config` and `kubeadm upgrade node experimental-control-plane` commands are deprecated in favor of `kubeadm upgrade node`, and will be removed in a future release. ([#78408](https://github.com/kubernetes/kubernetes/pull/78408), [@fabriziopandini](https://github.com/fabriziopandini))

Additionally, since the information returned from the discovery APIs may change dynamically, a cache of the results should not be considered authoritative.
ETag support is planned in a future version to facilitate client caching.

  * Verification against Kubernetes 1.8 is planned soon after the release.

* [stable] [frakti](https://github.com/kubernetes/frakti): CRI implementation for hypervisor-based runtimes is now v1.1. [[@feiskyer](https://github.com/feiskyer)]

  * Enhance CNI plugin compatibility, supports flannel, calico, weave and so on.
