The Flux language proposed in the paper makes it easier to _manually_ decompose a large program into smaller "concurrent servers."

Flow (and note that this is not the only new language being called Flow) seems to go for automatic parallelization; if successful, that's a fundamentally different approach versus Flux.

Yes, I have come across now fewer than five programming languages called Flow since posting the Flow Manifesto. It already has a new name, but the new name and info about the new directions of the project haven't been posted publicly yet.
