What's different between this mod and what the previous mod was? [Other than the fact that this mod isn't dead obviously]

What did you add? What did you remove? Please put that and a link to the original mod in the Information tab, because otherwise, people will hesitate on downloading this mod because they don't know what it does.

Apparently it uses a new 'liquid matter' resource for one, I'm uninstalling since the only way to get it is with pumps, and fluid transport, defeating the point of using the replicators mod for me in most ways.

It's strange, seems to be same mod as this:

The Dark Matter Replicators are still being maintained. Authors are different, i don't know what's going on.
