Thanks man. It was becoming increasingly difficult to keep track of the compiler changes and writing a book is hard enough without the target moving. Since I started it as a community project I decided to release it to the community as a token of goodwill. (Although on the FB forums I seems to be a bit reviled because of my association with certain ex-members.

)
I am not sure what has become of the book though. What you see in the preview is the writing I managed to complete on the book, with the exception of the license stuff. I don't visit the FB forums much anymore so I haven't been keeping track.
The other reason I released the project to the community was to free up some time for my fiction writing. I am working on an anthology and novel at the moment.
I like tech writing though, so I am currently working on a new tech book that will cover game design and game mechanics. The first half of the book covers game design, action plans, project management, that sort of thing. The second half will cover game mechanics such as path finding, AI techniques and stuff like that. This will be a generalized book (ie., not targeted to a particular language) which should appeal to a wider audience.
Anyway, thanks for the kind words. You might want to check the FB forums on the status of the book.
