- Fixed bug where health check could pass while APIServices are missing from aggregated discovery. ([#122883](https://github.com/kubernetes/kubernetes/pull/122883), [@Jefftree](https://github.com/Jefftree))

- Added new k8s.io/component-helpers repository providing shared helper code for (core) components. ([#92507](https://github.com/kubernetes/kubernetes/pull/92507), [@ingvagabund](https://github.com/ingvagabund)) [SIG Apps, Node, Release and Scheduling]

- Finished initial generic controlplane refactor of kube-apiserver, providing a sample binary building a Kubernetes-like control plane, but without container orchestration resources. ([#124530](https://github.com/kubernetes/kubernetes/pull/124530), [@sttts](https://github.com/sttts)) [SIG API Machinery, Apps, Cloud Provider,...

Advanced Profiling
------------------

Android Studio’s Advanced Profiling feature rewrites OkHttp bytecode for instrumentation.
Unfortunately it crashes on OkHttp 4.x’s bytecode. Until [Google’s bug][advanced_profiling_bug] is
fixed you must disable advanced profiling in Android Studio.

- Profiling can now be served on a unix-domain socket by using the `--profiling-path` option (when profiling is enabled) for security purposes. ([#114191](https://github.com/kubernetes/kubernetes/pull/114191), [@apelisse](https://github.com/apelisse)) [SIG API Machinery]
