### Introducing Graceful Node Shutdown (Alpha)

### Kubernetes release cadence change

### Serverside Apply - Beta 2

Server-side Apply was promoted to Beta in 1.16, but is now introducing a second Beta in 1.18. This new version will track and manage changes to fields of all new Kubernetes objects, allowing you to know what changed your resources and when.

### Extending Ingress with and replacing a deprecated annotation with IngressClass

### Auth

- Added `kubectl auth can-i --list` option, which allows users to  know what actions they can do in specific namespaces. ([#64820](https://github.com/kubernetes/kubernetes/pull/64820), [@WanLinghao](https://github.com/WanLinghao))

- The PR adds functionality to generate events when a PV or PVC processing encounters certain failures. The events help users to know the reason for the failure so they can take necessary recovery actions. ([#89845](https://github.com/kubernetes/kubernetes/pull/89845), [@yuga711](https://github.com/yuga711)) [SIG Apps]

* Kubernetes version command line parameter in kubeadm has been updated to drop an unnecessary redirection from ci/latest.txt to ci-cross/latest.txt. Users should know exactly where the builds are stored on Google Cloud storage buckets from now on. For example for 1.9 and 1.10, users can specify ci/latest-1.9 and ci/latest-1.10 as the CI build jobs what build images correctly updates those. The CI jobs for master...

- Scheduler throughput has been improved by ~50% in large clusters (>2000 nodes).

### SIG-service-catalog
- The Originating Identity feature, which lets the broker know which user that performed an action, is now GA.
- [Namespaced Brokers](https://svc-cat.io/docs/namespaced-broker-resources/), which enable operators to install a broker into a namespace instead of the cluster level, reached GA.
