* Fixed an issue with informers missing an `Added` event if a recently deleted object was immediately recreated at the same time the informer dropped a watch and relisted. ([#83911](https://github.com/kubernetes/kubernetes/pull/83911), [@matte21](https://github.com/matte21))

### Controller Manager

- `apiserver_dropped_requests` is dropped from this release since `apiserver_request_total` can now be used to track dropped requests. `etcd_object_counts` is also removed in favor of `apiserver_storage_objects`. `apiserver_registered_watchers` is also removed in favor of `apiserver_longrunning_requests`. ([#110337](https://git...

- Fixes a bug where a partial EndpointSlice update could cause node name information to be dropped from endpoints that were not updated. ([#108201](https://github.com/kubernetes/kubernetes/pull/108201), [@robscott](https://github.com/robscott)) [SIG Network]

- Added support for kube-proxy iptables mode to track packets that were wrongfully marked invalid by conntrack and subsequently dropped by introducing `kubeproxy_iptables_ct_state_invalid_dropped_packets_total` metric.

### Other notable changes

* kubeadm: run kube-proxy on non-master tainted nodes ([#65931](https://github.com/kubernetes/kubernetes/pull/65931), [@neolit123](https://github.com/neolit123))
* Fix an issue with dropped audit logs, when truncating and batch backends enabled at the same time. ([#65823](https://github.com/kubernetes/kubernetes/pull/65823), [@loburm](https://github.com/loburm))

* Add apiserver metric for number of requests dropped because of inflight limit. ([#58340](https://github.com/kubernetes/kubernetes/pull/58340), [@gmarek](https://github.com/gmarek))

* The Certificates API has graduated from alpha to beta. This is a backwards-incompatible change since the alpha support is dropped, and therefore kubeadm v1.5 and v1.6 don't work together (for example kubeadm v1.5 can't join a kubeadm v1.6 cluster).
* Supporting only etcd3, with 3.0.14 as the minimum version.
