using study material from 2009: outdated?

in Network+
I have a book from 2009
Amazon.com: CompTIA Network+ 2009 In Depth (9781598638783): Tamara Dean: Books
I'm concerned about its relevance to 2012 Network+ exam.
Does the exam content change rapidly? Or should I be fine with a 2009 textbook?
Thanks!!!!

charlesc09 is making a good point. When you register for the exam, ensure you register for the N10-004 exam. If you use this book and plan to take the N10-005 exam, you'll find that there are differences between the two exams.
