The Django Book is getting updated 
It is good to see the book is still alive.Django is one of the best documented projects I have ever seen. But I know people who have problems with the way the documentation is structured. For some parts you have to understand a completely different part of the framework to follow the documentation. This is to some degree a price you have to pay for a complex framework and is IMHO fine.But especially for those people is a book, which gives a structured way through the whole framework, a great thing.
