I commented on the state of the doc updating previously. Though the raw text of a version of WI that’s been updated in places is in the repo, I feel certain that it’s well-understood that it needs further revision. I don’t think that it’s a coincidence that the intools docs have been publicized while only perusers of the repo know WI is there. (I’ve submitted some tiny pull requests for WI changes and reported some missing things as bugs.)
I think it’s a safe bet that when it’s up-to-date, there will be shiny new automatically generated HTML and an epub at inform7.com and we’ll all know about it.
