### Instrumentation

- Kibana has been slightly revamped/improved in the latest version ([#80421](https://github.com/kubernetes/kubernetes/pull/80421), [@lostick](https://github.com/lostick))

### Network

- DRA: scheduling pods is up to 16x faster, depending on the scenario. Scheduling throughput depends a lot on cluster utilization. It is higher for lightly loaded clusters with free resources and gets lower when the cluster utilization increases.

- **Cluster Ops**
  - [alpha] Added ability to create/remove clusters w/highly available (replicated) masters on GCE using kube-up/kube-down scripts. ([docs](http://kubernetes.io/docs/admin/ha-master-gce/)) ([kubernetes/features#48](https://github.com/kubernetes/enhancements/issues/48))
- **Federation**

- When the `StrictIPCIDRValidation` feature gate is enabled, Kubernetes will be
  slightly stricter about what values will be accepted as IP addresses and network
  address ranges (“CIDR blocks”).
  
  In particular, octets within IPv4 addresses are not allowed to have any leading

* **[stable]** Volume plugin for Portworx added capability to use [Portworx](http://www.portworx.com) as a storage provider for Kubernetes clusters. Portworx pools server capacity and turns servers or cloud instances into converged, highly available compute and storage nodes.
* **[stable]** Add support to use NFSv3, NFSv4, and GlusterFS on GCE/GKE GCI image based clusters.
* **[beta]** Added support for mount options in persistent volumes.

- Fixed bug in `TopologyManager` for ensuring aligned allocations...
