- Added Custom Resource support to `kubectl autoscale` ([#72678](https://github.com/kubernetes/kubernetes/pull/72678), [@rmohr](https://github.com/rmohr))
- Cinder volume limit can now be configured from node too ([#74542](https://github.com/kubernetes/kubernetes/pull/74542), [@gnufied](https://github.com/gnufied))

  * Dynamic Provisioning of PersistentVolumes: Kubernetes previously required all
volumes to be manually provisioned by a cluster administrator before use. With
this feature, volume plugins that support it (GCE PD, AWS EBS, and Cinder) can
automatically provision a PersistentVolume to bind to an unfulfilled
PersistentVolumeClaim.
  * Run multiple schedulers in parallel, e.g. one or more custom schedulers

conjunction with SIG Cloud Provider, is focusing on moving internal APIs that the OpenStack (and other providers) depends upon to staging to guarantee API stability. This work also included abstracting the in-tree Cinder API and refactoring code to the external Cinder provider to remove additional Cinder volume provider code.

Additional work was also done to implement an OpenStack driver for the Cluster API effort lead by SIG Cluster Lifecycle. For the external Cloud-Provider-OpenStack code, the...

    Connections opened to fulfill this policy are subject to the connection pool's
    `keepAliveDuration` but do not count against the pool-wide `maxIdleConnections` limit.

    This feature increases the client's traffic and the load on the server. Talking to your server's
    operators before adopting it.

- OpenStack Cinder CSI migration is now GA and switched on by default, Cinder CSI driver must be installed on clusters on OpenStack for Cinder volumes to work (has been since v1.21). ([#107462](https://github.com/kubernetes/kubernetes/pull/107462), [@dims](https://github.com/dims))

* Scheduling conformance tests related to daemonsets should set the annotation that relaxes node selection restrictions, if any are set. This ensures conformance tests can run on a wider array of clusters. ([#68793](https://github.com/kubernetes/kubernetes/pull/68793), [@aveshagarwal](https://github.com/aveshagarwal))

 *  Fix: Recover gracefully if the TLS session returns an unexpected version (`NONE`) or cipher
    suite (`SSL_NULL_WITH_NULL_NULL`).
 *  Fix: Don't change Conscrypt configuration globally. We migrated from a process-wide setting to
    configuring only OkHttp's TLS sockets.
 *  Fix: Prefer TLSv1.2 where it is available. On certain older platforms it is necessary to opt-in
    to TLSv1.2.

- Added categories column to the `kubectl api-resources` command's wide output (`-o wide`).

* GCI/Trusty: Support ABAC authorization ([#24950](https://github.com/kubernetes/kubernetes/pull/24950), [@andyzheng0831](https://github.com/andyzheng0831))
* fix cinder volume dir umount issue [#24717](https://github.com/kubernetes/kubernetes/pull/24717) ([#24718](https://github.com/kubernetes/kubernetes/pull/24718), [@chengyli](https://github.com/chengyli))
