* Build hyperkube in hack/local-up-cluster instead of separate binaries ([#25627](https://github.com/kubernetes/kubernetes/pull/25627), [@luxas](https://github.com/luxas))
* enable recursive processing in kubectl rollout ([#25110](https://github.com/kubernetes/kubernetes/pull/25110), [@metral](https://github.com/metral))

* let patch use --local flag like `kubectl set image` ([#26722](https://github.com/kubernetes/kubernetes/pull/26722), [@deads2k](https://github.com/deads2k))
* enable recursive processing in kubectl edit ([#25085](https://github.com/kubernetes/kubernetes/pull/25085), [@metral](https://github.com/metral))

- Fixed null `lastTransitionTime` in Pod condition when setting the scheduling gate. ([#122636](https://github.com/kubernetes/kubernetes/pull/122636), [@lianghao208](https://github.com/lianghao208)) [SIG Node and Scheduling]
- Fixed recursive LIST from watch cache returning object matching key. ([#125584](https://github.com/kubernetes/kubernetes/pull/125584), [@serathius](https://github.com/serathius)) [SIG API Machinery and Testing]

- KEP-3857: Recursive Read-only (RRO) mounts: promote to GA ([#130116](https://github.com/kubernetes/kubernetes/pull/130116), [@AkihiroSuda](https://github.com/AkihiroSuda)) [SIG Apps, Node and Testing]

SIG Storage is also introducing the following new storage features as alpha in Kubernetes 1.18:
- Windows CSI Support: Enabling containerized CSI node plugins in Windows via new [CSIProxy](https://github.com/kubernetes-csi/csi-proxy)
- Recursive Volume Ownership OnRootMismatch Option: Add a new “OnRootMismatch” policy that can help shorten the mount time for volumes that require ownership change and have many directories and files.

### Other notable announcements

- Deprecated the following kubectl run flags, which are ignored if set: `--cascade`, `--filename`, `--force`, `--grace-period`, `--kustomize`, `--recursive`, `--timeout`, `--wait`. ([#112261](https://github.com/kubernetes/kubernetes/pull/112261), [@brianpursley](https://github.com/brianpursley))
