* Action required: validation rule on metadata.initializers.pending[x].name is tightened. The initializer name needs to contain at least three segments separated by dots. If you create objects with pending initializers, (i.e., not relying on apiserver adding pending initializers according to initializerconfiguration), you need to update the initializer name in existing objects and in configuration files to comply...

* Add the support to the scheduler for spreading pods of StatefulSets. ([#41708](https://github.com/kubernetes/kubernetes/pull/41708), [@bsalamat](https://github.com/bsalamat))
* Added support to minimize sending verbose node information to scheduler extender by sending only node names and expecting extenders to cache the rest of the node information ([#41119](https://github.com/kubernetes/kubernetes/pull/41119), [@sarat-k](https://github.com/sarat-k))

- Updates that remove remaining `metadata.finalizers` from  an object that is pending deletion (non-nil metadata.deletionTimestamp) and has no graceful deletion pending (nil or 0 metadata.deletionGracePeriodSeconds) now results in immediate deletion of the object. ([#77952](https://github.com/kubernetes/kubernetes/pull/77952), [@liggitt](https://github.com/liggitt))

- Added new functionality to the Go client code (`client-go`) library. The `List()` method for the metadata client allows enabling API streaming when fetching collections; this improves performance when listing many objects.

- Fix route conflicted operations when updating multiple routes together ([#88209](https://github.com/kubernetes/kubernetes/pull/88209), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]

* Fix public IP not found issues for VMSS nodes ([#80703](https://github.com/kubernetes/kubernetes/pull/80703), [@feiskyer](https://github.com/feiskyer))
* Resolves a bug that prevented sending a multi-version custom resource to an admission webhook. ([#79495](https://github.com/kubernetes/kubernetes/pull/79495), [@liggitt](https://github.com/liggitt))

  - Clone `kubernetes/kubernetes` in `update-vendor.sh` shallowly, instead of fetching all revisions
  - Speed up binpacking by reducing the number of PreFilter calls (call once per pod instead of #pods*#nodes times)
  - Speed up finding unneeded nodes by 5x+ in very large clusters by reducing the number of PreFilter calls
  - Expose `--max-nodes-total` as a metric

    * try to only update vm if detach a non-existing disk when got <200, error> after detach disk operation
* This adds some useful metrics around pending changes and last successful ([#78602](https://github.com/kubernetes/kubernetes/pull/78602), [@paulgmiller](https://github.com/paulgmiller))
    * sync time.
