Its type must be a <a href="#Type_definitions">defined</a> type <code>T</code> or a
pointer to a defined type <code>T</code>, possibly followed by a list of type parameter
names <code>[P1, P2, …]</code> enclosed in square brackets.
<code>T</code> is called the receiver <i>base type</i>. A receiver base type cannot be
a pointer or interface type and it must be defined in the same package as the method.

* CRI now defines mounting behavior. If the host path doesn't exist, the runtime should return an error. If the host path is a symlink, the runtime should follow the symlink and mount the real destination to the container. ([#61460](https://github.com/kubernetes/k...

    Potential impacts:

- When scaling down a ReplicaSet, delete doubled up replicas first, where a "doubled up replica" is defined as one that is on the same node as an active replica belonging to a related ReplicaSet.  ReplicaSets are considered "related" if they have a common controller (typically a Deployment). ([#80004](https://github.com/kubernetes/kubernetes/pull/80004),...

In-tree bug fixes and improvements included:
- Fix load balancer status without VIP.
- Fix filtering of server status.
- Fix resizing PVC of Cinder volume.
- Disable load balancer configuration if it is not defined in cloud config.
- Add support for node shutdown taint.

The external provider includes all of the above with the additional fixes and features:
- Fix bug to prevent allocation of existing floating IP.

- Added support for in-place vertical scaling of Pods with sidecars (containers defined within `initContainers` where the `restartPolicy` is set to `Always`).

controller manager binary. Additionally we added [aws-k8s-tester](https://github.com/kubernetes/test-infra/issues/9814), deployer interface for kubetest, to the test-infra repository. This plugin allowed us to integrate Prow to the 3 subprojects defined above in order to provide CI signal for all 3 features. The CI signal is visible [here](https://testgrid.k8s.io/) under SIG-AWS.

For detailed release notes on the three alpha features from SIG AWS, please refer to the following Changelogs:...

- Improved scheduler performance when no scoring plugins were defined.

- Improved scheduler performance when no scoring plugins were defined.

- The go version defined in `.go-version` is now fetched when invoking test, build, and code generation targets if the current go version does not match it. Set $FORCE_HOST_GO=y while testing or building to skip this behavior, or set $GO_VERSION to override the selected go...

* Kubernetes now supports up to 5,000 nodes via etcd v3, which is enabled by default.
* [Role-based access control (RBAC)](https://kubernetes.io//docs/admin/authorization/rbac) has graduated to beta, and defines secure default roles for control plane, node, and controller components.
* The [`kubeadm` cluster bootstrap tool](https://kubernetes.io/docs/getting-started-guides/kubeadm/) has graduated to beta. Some highlights:
