- The bug which caused the status of Indexed Jobs to only update when new indexes were completed was fixed. Now, completed indexes are updated even if the `.status.completedIndexes` values are outside the `[0, .spec.completions> range`.

  Also `metricsBindAddress` and `healthzBindAddress` fields from `kubescheduler.config.k8s.io/v1beta1` are no-op and expected to be empty. Removed in `kubescheduler.config.k8s.io/v1beta2` completely.

  In addition, please be careful that:

- Improved air-gapped and offline support
  - kubeadm now handles air-gapped environments by using the local client version as a fallback.
  - Some kubeadm commands are now allowed to work in a completely offline mode.
- Certificate handling improvements:
  - Renew certs as part of upgrade.
  - New `kubeadm alpha phase certs renew` command for renewing certificates.
