- Passing an invalid policy name in the `--cpu-manager-policy` flag will now cause the kubelet to fail instead of simply ignoring the flag and running the `cpumanager`’s default policy instead. ([#80294](https://github.com/kubernetes/kubernetes/pull/80294), [@klueska](https://github.com/klueska))

- Added kubelet metrics to track the cpumanager cpu allocation and pinning ([#112855](https://github.com/kubernetes/kubernetes/pull/112855), [@fromanirh](https://github.com/fromanirh))
- Added new Golang runtime-related metrics to Kubernetes components:

* Bugfix allowing use of IP-aliases with custom-mode network in GCE setup scripts. ([#62172](https://github.com/kubernetes/kubernetes/pull/62172), [@shyamjvs](https://github.com/shyamjvs))
