We got a good build and the package is going through some final validation steps and will then go to NuGet.

@dasetser will update and close this issue once it gets to NuGet.

@pmiddleton We are proceeding with the final packaging changes, we can’t wait on #4154. Assuming no complications we are shooting for a release to NuGet next week.
