- 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]

- Kube-controller-manager and kube-scheduler expose profiling by default to match the kube-apiserver.  Use `--profiling=false` to disable. ([#88663](https://github.com/kubernetes/kubernetes/pull/88663), [@deads2k](https://github.com/deads2k)) [SIG API Machinery, Cloud Provider and Scheduling]

- Profiling is enabled by default in the scheduler ([#84835](https://github.com/kubernetes/kubernetes/pull/84835), [@denkensk](https://github.com/denkensk))

* Fix comment and optimize code ([#38084](https://github.com/kubernetes/kubernetes/pull/38084), [@tanshanshan](https://github.com/tanshanshan))
* Add flag to enable contention profiling in scheduler. ([#37357](https://github.com/kubernetes/kubernetes/pull/37357), [@gmarek](https://github.com/gmarek))

* Refactor calling each a path operation's handler function in an isolated function, to simplify profiling. PR [#1027](https://github.com/tiangolo/fastapi/pull/1027) by [@sm-Fifteen](https://github.com/sm-Fifteen).

[SIG Storage][] is responsible for storage and volume plugin components.

For the 1.8 release, SIG Storage extended the Kubernetes storage API. In addition to providing simple
volume availability, the API now enables volume resizing and snapshotting. These features are in alpha.
The SIG also focused on providing more control over storage: the ability to set requests and

- 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.
