- Fixed an issue where kubelet does not set case-insensitive headers for http probes. (#117182, @dddddai) ([#117324](https://github.com/kubernetes/kubernetes/pull/117324), [@dddddai](https://github.com/dddddai)) [SIG API Machinery, Apps and Node]

* azure: update disk lock logic per vm during attach/detach to allow concurrent updates for different nodes. ([#85115](https://github.com/kubernetes/kubernetes/pull/85115), [@aramase](https://github.com/aramase))
* Ensure health probes are created for local traffic policy UDP services on Azure ([#85327](https://github.com/kubernetes/kubernetes/pull/85327), [@nilo19](https://github.com/nilo19))

* allow group impersonation ([#30803](https://github.com/kubernetes/kubernetes/pull/30803), [@deads2k](https://github.com/deads2k))
* Always return command output for exec probes and kubelet RunInContainer ([#30731](https://github.com/kubernetes/kubernetes/pull/30731), [@ncdc](https://github.com/ncdc))

- We have added a new Priority & Fairness rule that exempts all probes (/readyz, /healthz, /livez) to prevent 
  restarting of "healthy" kube-apiserver instance(s) by kubelet. ([#101111](https://github.com/kubernetes/kubernetes/pull/101111), [@tkashem](https://github.com/tkashem)) [SIG API Machinery]
