### Bug or Regression

- Added jitter factor to lease controller that better smears load on kube-apiserver over time. ([#101652](https://github.com/kubernetes/kubernetes/pull/101652), [@marseel](https://github.com/marseel)) [SIG API Machinery and Scalability]

- The `metadata.clusterName` field is completely removed. This should not have any user-visible impact. ([#109602](https://github.com/kubernetes/kubernetes/pull/109602), [@lavalamp](https://github.com/lavalamp))

- Updated CNI plugins to v1.7.1 ([#131602](https://github.com/kubernetes/kubernetes/pull/131602), [@adrianmoisey](https://github.com/adrianmoisey)) [SIG Cloud Provider, Node and Testing]
