*   distribute.experimental.rpc package:

    *   distribute.experimental.rpc package introduces APIs to create a GRPC
        based server to register tf.function methods and a GRPC client to invoke
        remote registered methods. RPC APIs are intended for multi-client setups
        i.e. server and clients are started in separate binaries independently.

* You now have the ability to quota resources by priority. ([#57963](https://github.com/kubernetes/kubernetes/pull/57963), [@vikaschoudhary16](https://github.com/vikaschoudhary16))
* The gRPC max message size in the remote container runtime has been increased to 16MB. ([#64672](https://github.com/kubernetes/kubernetes/pull/64672), [@mcluseau](https://github.com/mcluseau))

* support imagePullSecrets and imagePullPolicy in kubefed init ([#50740](https://github.com/kubernetes/kubernetes/pull/50740), [@dixudx](https://github.com/dixudx))
* update gRPC to v1.6.0 to pick up data race fix grpc/grpc-go#1316  ([#53128](https://github.com/kubernetes/kubernetes/pull/53128), [@dixudx](https://github.com/dixudx))

* Re-issue Allocate grpc calls before starting a container that requests device-plugin resources if the cached state is missing. ([#73824](https://github.com/kubernetes/kubernetes/pull/73824), [@jiayingz](https://github.com/jiayingz))

* In anticipation of CSI 1.0 in the next release, Kubernetes 1.12 calls the CSI `NodeGetInfo` RPC instead of `NodeGetId` RPC. Ensure your CSI Driver implements `NodeGetInfo(...)` before upgrading to 1.12. [@saad-ali](https://github.com/kubernetes/kubernetes/issues/68688)
