  // The way the `table`, `entries`, `keys`, and `values` arrays work together is as follows.
  //
  // The `table` array always has a size that is a power of 2. The hashcode of a key in the map
  // is masked in order to correspond to the current table size. For example, if the table size
  // is 128 then the mask is 127 == 0x7f, keeping the bottom 7 bits of the hash value.

- Improved CRI handling
  - crictl is no longer required in docker-only setups.
  - Better detection of installed CRI.
  - Better output for image pull errors.
- 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:

- etcd version monitor metrics are now marked as with the ALPHA stability level. ([#83283](https://github.com/kubernetes/kubernetes/pull/83283), [@RainbowMango](https://github.com/RainbowMango))
- Change `pod_preemption_victims` metric from Gauge to Histogram. ([#83603](https://github.com/kubernetes/kubernetes/pull/83603), [@Tabrizian](https://github.com/Tabrizian))
- Following metrics from kubelet are now marked as with the ALPHA stability level:

 * conformance of concrete {@link Map} subclasses to that contract.
 *
 * @param <K> the type of keys used by the maps under test
 * @param <V> the type of mapped values used the maps under test
