The book has been at 4th edition for a while and I'm sure there have been updates since then. The edition numbers may tick over at major updates,but is it possible to put a last update date on it to tell when it has changed.
One thing we talked about before version 2 was getting the doco up to date ASAP, we even talked about delaying the release, or at least it's announcement till that was done. I'm not sure if that has actually happened yet (completely) Eg. Waiting to see updates around replacing plugin_wiki with auth.wiki (I think that's the strategy). I would like to deploy an app soon using it but its not quite there yet. Happy to help too. Thanks --
