I purchased the 2nd edition a while back. I am only now getting back into Rails development, and would like to use a resource to guide me through the depot section of the book, with the changes of 2.1.
So my question is how far is the beta done? How many chapters have been covered? Half the book, less then half, more then half? Is it worth getting now and working through it?
Or is he just doing updates all over the book instead of chronically from beginning to end?
