* kubeadm has removed `.Etcd.SelfHosting` from its configuration API. It was never used in practice ([#63871](https://github.com/kubernetes/kubernetes/pull/63871), [@luxas](https://github.com/luxas))

  - increases the weight of user specifiable priorities.
  The weights of following priority plugins are increased
    - `TaintTolerations` to 3 - as leveraging node tainting to group nodes in the cluster is becoming a widely-adopted practice
    - `NodeAffinity` to 2
    - `InterPodAffinity` to 2
  

- Recording timing traces had a race condition. Impact in practice was probably low. ([#117139](https://github.com/kubernetes/kubernetes/pull/117139), [@pohly](https://github.com/pohly)) [SIG API Machinery, Architecture, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node and Storage]

  - The deprecated `--etcd-quorum-read` flag has been removed. Quorum reads are now always enabled when fetching data from etcd. Remove...

    *   You can manually set `--cloud-provider=auto-detect`, but be aware that this behavior will be removed completely in a future version.
    *   Best practice for version 1.9 and future versions is to explicitly set a cloud-provider. See [the documentation](https://kubernetes.io/docs/getting-started-guides/scratch/#cloud-providers)

// In practice, the maximum scratch buffer size should not exceed 512 KB due to
