- If `ComponentSLIs` feature gate is enabled, then `/metrics/slis` becomes available on kubelet, allowing you to scrape health check metrics. ([#113030](https://github.com/kubernetes/kubernetes/pull/113030), [@Richabanker](https://github.com/Richabanker)) [SIG Node]

* Demoted controlplane passthrough flags apiserver-extra-args, controller-manager-extra-args, scheduler-extra-args to alpha flags ([#59882](https://github.com/kubernetes/kubernetes/pull/59882), [@kris-nova](https://github.com/kris-nova))

## Changelog since v1.29.1

## Changes by Kind

### Feature

- Add process_start_time_seconds to /metrics/slis endpoint of all components ([#122750](https://github.com/kubernetes/kubernetes/pull/122750), [@richabanker](https://github.com/richabanker)) [SIG Architecture, Instrumentation and Testing]
- Kubernetes is now built with go 1.21.7

- Limit the body length of exec readiness/liveness probes. remote CRIs and Docker shim read a max of 16MB output of which the exec probe itself inspects 10kb. ([#82514](https://github.com/kubernetes/kubernetes/pull/82514), [@dims](https://github.com/dims))
