- kubeadm will now print required flags when running `kubeadm upgrade plan`.([#65802](https://github.com/kubernetes/kubernetes/pull/65802), [@xlgao-zju](https://github.com/xlgao-zju))
- Unix support for ZFS as a valid graph driver has been added for Docker, enabling users to use Kubeadm with ZFS. ([#65635](https://github.com/kubernetes/kubernetes/pull/65635), [@neolit123](https://github.com/neolit123))

* Fix TestServiceAlloc flakes ([#37487](https://github.com/kubernetes/kubernetes/pull/37487), [@wojtek-t](https://github.com/wojtek-t))
* Change ScheduledJob POD name suffix from hash to Unix Epoch ([#36883](https://github.com/kubernetes/kubernetes/pull/36883), [@jakub-d](https://github.com/jakub-d))

- Profiling can now be served on a unix-domain socket by using the `--profiling-path` option (when profiling is enabled) for security purposes. ([#114191](https://github.com/kubernetes/kubernetes/pull/114191), [@apelisse](https://github.com/apelisse)) [SIG API Machinery]

   2. CacheSize type was changed from int32 to *int32. This allows defaulting logic to differentiate between cases where users explicitly supplied 0 vs. not supplied any value.
   3. KMS Provider's endpoint (path to Unix socket) is now validated when the EncryptionConfiguration files is loaded. This used to be handled by the GRPCService.

### Other notable changes

- Enabled the `node-local` kubelet podresources API endpoint on windows, alongside unix. ([#115133](https://github.com/kubernetes/kubernetes/pull/115133), [@ffromani](https://github.com/ffromani))

- Kube-apiserver, kube-scheduler and kube-controller manager now use SO_REUSEPORT socket option when listening on address defined by --bind-address and --secure-port flags, when running on Unix systems (Windows is NOT supported). This allows to run multiple instances of those processes on a single host with the same configuration, which allows to update/restart them in a graceful way, without causing downtime.
