* Set kernel.softlockup_panic =1 based on the flag. ([#38001](https://github.com/kubernetes/kubernetes/pull/38001), [@dchen1107](https://github.com/dchen1107))
* Configure local-up-cluster.sh to handle auth proxies ([#36838](https://github.com/kubernetes/kubernetes/pull/36838), [@deads2k](https://github.com/deads2k))

    * sync time.
 
    * The goal is for administrators to be able to alert on proxies that, for
    * whatever reason, are quite stale.

* Adds feature gate for plugin watcher ([#64605](https://github.com/kubernetes/kubernetes/pull/64605), [@vikaschoudhary16](https://github.com/vikaschoudhary16))

- Fixed issue with Winkernel Proxier - IPV6 load balancer policies were missing when service was configured with `ipFamilyPolicy`: `RequireDualStack` ([#115503](https://github.com/kubernetes/kubernetes/pull/115503), [@princepereira](https://github.com/princepereira))

* Dual stack services (Phase II of IPv6DualStack feature) are enabled via the IPVS proxier. iptables proxier does not support dualstack yet. Dualstack iptables proxier is WIP and should catchup soon. ([#82091](https://github.com/kubernetes/kubernetes/pull/82091), [@khenidak](https://github.com/khenidak))
    * to enable, kube-proxy must be have the following flags:

  The API Server will no longer proxy non-101 responses for upgrade requests. This could break proxied backends (such as an extension API server) that respond to upgrade requests with a non-101 response code. ([#92941](https://github.com/kubernetes/kubernetes/pull/92941), [@tallclair](https://github.com/tallclair)) [SIG API Machinery]
 

- IPVS proxier now set net/ipv4/vs/conn_reuse_mode to 0 by default, which will highly improve IPVS proxier performance. ([#71114](https://github.com/kubernetes/kubernetes/pull/71114), [@Lion-Wei](https://github.com/Lion-Wei))

- Fixing issue with Winkernel Proxier - ClusterIP Loadbalancers are missing if the ExternalTrafficPolicy is set to Local and the available endpoints are all remoteEndpoints.
