* Pods that are marked for deletion and have exceeded their grace period, but are not yet deleted, no longer count toward the resource quota.([#46542](https://github.com/kubernetes/kubernetes/pull/46542))


#### Dynamic Admission Control

- Fixed a bug where startupProbe stopped working after a container's first restart ([#101093](https://github.com/kubernetes/kubernetes/pull/101093), [@wzshiming](https://github.com/wzshiming)) [SIG Node]
- Fixed port-forward memory leak for long-running and heavily used connections. ([#99839](https://github.com/kubernetes/kubernetes/pull/99839), [@saschagrunert](https://github.com/saschagrunert)) [SIG API Machinery and Node]

- `KMSv1` is deprecated and will only receive security updates going forward. Use `KMSv2` instead. In a future release, Set `--feature-gates=KMSv1=true` to use the deprecated KMSv1 feature. ([#119007](https://github.com/kubernetes/kubernetes/pull/119007), [@aramase](https://github.com/aramase))

// PodPortForwardOptions is the query options to a Pod's port forward call
// when using WebSockets.
// The `port` query parameter must specify the port or
// ports (comma separated) to forward over.
// Port forwarding over SPDY does not use these options. It requires the port
// to be passed in the `port` header as part of request.
message PodPortForwardOptions {
  // List of ports to forward
  // Required when using WebSockets

### SIG-windows

SIG Windows focused on stability and reliability of our existing feature set. We primarily fixed bugs as we march towards a near future stable release.

## Action Required

- etcd2 as a backend is deprecated and support will be removed in Kubernetes 1.13.

- Use online nodes instead of possible nodes when discovering available NUMA nodes ([#83196](https://github.com/kubernetes/kubernetes/pull/83196), [@zouyee](https://github.com/zouyee))
- Use IPv4 in wincat port forward. ([#83036](https://github.com/kubernetes/kubernetes/pull/83036), [@liyanhui1228](https://github.com/liyanhui1228))
