As a Zig adopter I was rooting for this because even though there is the official documentation and some great community content, it's nice to just kick back and read a well written book. I'm also very happy with other Manning titles; they have built a high level of trust with me.

To answer your question is it too early. My expectation is that the core language, being quite small by design, will not change that much before 1.0. Some things will, especially async support.

What I think we will see is something like a comprehensive book on C++14 . The language is not much changed between now and then, but there will be new sections to add and some sections to rework with changes to the interface. The book would still be useful today.

Not a perfect analogy because C++ maintains backwards compatibility but I think it is close.
