Forum:SH:When is it ok to add content from "A New Dawn"?

So this recently-past Comic-Con, Del Rey was handing out an Advanced Reader Edition of Star Wars: A New Dawn and I was one of the lucky individuals to receive a copy. Having recently finished the book, I was wondering if it would be ok to create articles relevant/expand those existing on topics found in A New Dawn. I ask this because being the Advanced Reader Edtion, it is out several months before official release and it does have the disclaimer of being an "uncorrected proof," though I'm under the impression any changed made would be story agnostic and likely be about fixing typos.
