- Scheduler doesn't run plugin's Filter method when its PreFilter method returned a Skip status.
  In other words, your PreFilter/Filter plugin can return a Skip status in PreFilter if the plugin does nothing in Filter for that Pod.
  Scheduler skips NodeAffinity Filter plugin when NodeAffinity Filter plugin has nothing to do with a Pod.

- Pod status updates faster when reacting on probe results. The first readiness probe will be called faster when startup probes succeeded, which will make Pod status as ready faster. ([#98376](https://github.com/kubernetes/kubernetes/pull/98376), [@matthyx](https://github.com/matthyx))

* A new predicates, named 'CheckNodeCondition', was added to replace node condition filter. 'NetworkUnavailable', 'OutOfDisk' and 'NotReady' maybe reported as a reason when failed to schedule pods. ([#51117](https://github.com/kubernetes/kubernetes/pull/51117), [@k82cn](https://github.com/k82cn))

### CLI

This release includes a change to [kubectl get and describe to work better with extensions](https://github.com/kubernetes/enhancements/issues/515), as the server, rather than the client, returns this information for a smoother user experience.

- The scheduler skips the `PodTopologySpread` Filter plugin if no spread constraints.
  It will affect some metrics values related to the `PodTopologySpread` Filter plugin. ([#117683](https://github.com/kubernetes/kubernetes/pull/117683), [@utam0k](https://github.com/utam0k))

  - Different configuration types can be supplied all in the same file separated by `---`.
- 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.

behavior of some watch calls to the server when filtering on fields was incorrect.  If watching objects with a filter, when an update was made that no longer matched the filter a DELETE event was correctly sent.  However, the object that was returned by that delete was not the (correct) version before the update, but instead, the newer version.  That meant the new object was not matched by the filter.  This was a regression from behavior between cached watches on the server side and uncached watches, and...
