* The Container Runtime Interface (CRI) version has increased from v1alpha1 to v1alpha2. Runtimes implementing the CRI will need to update to the new version, which configures container namespaces using an enumeration rather than booleans. This change to the alpha API is not backwards compatible; implementations of the CRI such as containerd, will need to update to the new API version.

  applied when username.claim is set to 'email' is 'claims.?email_verified.orValue(true) == true'. 
  By explicitly comparing the value to true, we let type-checking see the result will be a boolean, 
  and to make sure a non-boolean `email_verified` claim will be caught at runtime. ([#130875](https://github.com/kubernetes/kubernetes/pull/130875), [@aramase](https://github.com/aramase)) [SIG Auth and Release]

* Added the `writable` boolean option to kubeadm config. This option works on a per-volume basis for `ExtraVolumes` config keys. ([#60428](https://github.com/kubernetes/kubernetes/pull/60428), [@rosti](https://github.com/rosti))
