@gyuho meanwhile we wait on Joe's review, I also looked at it considering we had some discussion around this while moving to Go 1.12.x. It looks good to me with a probably nit as mentioned inline. Thanks!!

@gyuho just a nit - useDeprecating (or Deprecated) instead of Deprecate to be consistent with the rest of the changelog and other places like upgrade_3_4.md?

Since this is due to the grpc upgrade, put the exact grpc upgrade version as a high level release change note and put this item as note beneath it?
