* kube-apiserver: the default `--endpoint-reconciler-type` is now `lease`. The `master-count` endpoint reconciler type is deprecated and will be removed in 1.13. ([#63383](https://github.com/kubernetes/kubernetes/pull/63383), [@liggitt](https://github.com/liggitt))

### Bug or Regression

- Fix endpoint reconciler not being able to delete the apiserver lease on shutdown ([#114138](https://github.com/kubernetes/kubernetes/pull/114138), [@aojea](https://github.com/aojea)) [SIG API Machinery]

    * --alpha-endpoint-reconciler-type=(master-count, lease, none) (default
    * "master-count"). The original reconciler is 'master-count'. The 'lease'
    * reconciler uses the storageapi and a TTL to keep alive an endpoint within the
    * `kube-apiserver-endpoint` storage namespace. The 'none' reconciler is a noop

### Bug or Regression

- Fixed a bug where a high churn of events was causing master instability by reducing the maximum number of objects (events) attached to a single etcd lease.

- LeaseLocks could now have custom labels that different holders would overwrite when they became the holder of the underlying lease. ([#131632](https://github.com/kubernetes/kubernetes/pull/131632), [@DerekFrank](https://github.com/DerekFrank))
