with to go1.18, which introduced significant changes to its garbage collection algorithm. As a result, we observed an increase in memory usage for kube-apiserver in larger an heavily loaded clusters up to ~25% (with the benefit of API call latencies drop by up to 10x on 99th percentiles). If the memory increase is not acceptable for you you can mitigate by setting GOGC env variable (for our tests using GOGC=63 brings memory usage back to original value, although the exact value may depend on usage...

- Deprecate kubectl top flags related to heapster
  Drop support of heapster in kubectl top ([#87498](https://github.com/kubernetes/kubernetes/pull/87498), [@serathius](https://github.com/serathius)) [SIG CLI]
- Deprecate the `--target-ram-md` flags that is no longer used for anything. ([#91818](https://github.com/kubernetes/kubernetes/pull/91818), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery]

- Fixed graceful apiserver shutdown to not drop outgoing bytes before the process terminates. ([#72970](https://github.com/kubernetes/kubernetes/pull/72970), [@sttts](https://github.com/sttts))

### Apps

* Fix bug where EndpointSlice controller would attempt to modify shared objects. ([#85368](https://github.com/kubernetes/kubernetes/pull/85368), [@robscott](https://github.com/robscott))
* Revert ensure the KUBE-MARK-DROP chain in kube-proxy mode=iptables. Fix a bug in which kube-proxy deletes the rules associated with the chain in iptables mode. ([#85527](https://github.com/kubernetes/kubernetes/pull/85527), [@aojea](https://github.com/aojea))

* Kubernetes version command line parameter in kubeadm has been updated to drop an unnecessary redirection from ci/latest.txt to ci-cross/latest.txt. Users should know exactly where the builds are stored on Google Cloud storage buckets from now on. For example for 1.9 and 1.10, users can specify ci/latest-1.9 and ci/latest-1.10...
