  -  Remove already deprecated options `resyncperiod` and `upstream` in the Kubernetes plugin.
  -  Includes Prometheus metrics name changes (to bring them in line with standard Prometheus metrics naming convention). They will be backward incompatible with existing reporting formulas that use the old metrics' names.
  -  The federation plugin (allows for v1 Kubernetes federation) has been removed.

* Update debian-iptables and hyperkube-base images to include CVE fixes. ([#67365](https://github.com/kubernetes/kubernetes/pull/67365), [@ixdy](https://github.com/ixdy))
* Immediately close the other side of the connection when proxying. ([#67288](https://github.com/kubernetes/kubernetes/pull/67288), [@MHBauer](https://github.com/MHBauer))

### SIG Node

- Packets considered INVALID by conntrack are now dropped. In particular, this fixes
a problem where spurious retransmits in a long-running TCP connection to a service
IP could result in the connection being closed with the error "Connection reset by
peer" ([#74840](https://github.com/kubernetes/kubernetes/pull/74840), [@anfernee](https://github.com/anfernee))

* After a kubelet rotates its client cert, it now closes its connections to the API server to force a handshake using the new cert. Previously, the kubelet could keep its existing connection open, even if the cert used for that connection was expired and rejected by the API server. ([#49899](https://github.com/kubernetes/kubernetes/pull/49899), [@ericchiang](https://github.com/ericchiang))
