Is my book out of date?

Hi Guys. When I signed up to ACCA a few months ago I bought the F2 & F3 books. (F1 exemption). I have just finished studying the F3 module and sat the exam. Was a great experience so far.

Now I am about to start the F2 process. I noticed though that my Kaplan book is dated until the 31st of December. Since discovering this website I plan to use the videos and online notes but I feel I should use the book too as I paid for it. Will it be missing sections as its just out of date?

I also bought a F2 study kit back then. Will the new one be very different as the exam format is changing?

Thanks for any help!!
