Required nuget-package Microsoft.Tpl.Dataflow doesn't exist anymore.

The current latest version of EPiServer.CMS.Core (11.9.4) has a dependency on a Nuget package that doesn't exist anymore.

https://www.nuget.org/packages/Microsoft.Tpl.Dataflow/4.5.24

I can only assume it's been recently delisted and hopefully the next release of EPi won't reference it? From what I can see:

https://www.nuget.org/packages/System.Threading.Tasks.Dataflow/

...may be what should be used from now on?

Am I correct, and there will be an update soon? If not. How am I to solve this issue? I can't install my packages at the moment.

I am targeting .NET 4.6.1
