* Upgrade to etcd client 3.3.17 to fix bug where etcd client does not parse IPv6 addresses correctly when members are joining, and to fix bug where failover on multi-member etcd cluster fails certificate check on DNS mismatch ([#83968](https://github.com/kubernetes/kubernetes/pull/83968), [@jpbetz](https://github.com/jpbetz))

- If `kubeadm reset` finds no etcd member ID for the peer it removes during the `remove-etcd-member` phase, it continues immediately to other phases, instead of retrying the phase for up to 3 minutes before continuing. ([#118192](https://github.com/kubernetes/kubernetes/pull/118192), [@dlipovetsky](https://github.com/dlipovetsky))...

- Kubeadm: fixed issue where etcd member promotion fails with an error saying the member was already promoted ([#132280](https://github.com/kubernetes/kubernetes/pull/132280), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

### Other (Cleanup or Flake)

- Kubeadm: during "join", don't re-add an etcd member if it already exists in the cluster. ([#92118](https://github.com/kubernetes/kubernetes/pull/92118), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

* Remove pids cgroup controller requirement when related feature gates are disabled ([#79073](https://github.com/kubernetes/kubernetes/pull/79073), [@rafatio](https://github.com/rafatio))
* Fix remove the etcd member from the cluster during a kubeadm reset. ([#79326](https://github.com/kubernetes/kubernetes/pull/79326), [@bradbeam](https://github.com/bradbeam))



# v1.15.0

[Documentation](https://docs.k8s.io)

- The `apiserver` exposes 4 new metrics that allow to track the status of the Service CIDRs allocations:
      - current number of available IPs per Service CIDR
      - current number of used IPs per Service CIDR
      - total number of allocation per Service CIDR
      - total number of allocation errors per ServiceCIDR ([#104119](https://github.com/kubernetes/kubernetes/pull/104119), [@aojea](https://github.com/aojea))

 *  Fix: Don't drop repeated headers when validating cached responses. In our Kotlin upgrade we
    introduced a regression where we iterated the number of unique header names rather than then
    number of unique headers. If you're using OkHttp's response cache this may impact you.
