Death Korps of Kreig and new IA: Siege of Vraks

[Cadian122]

So I've just come back into the hobby after about 6 months break and I have noticed that there is a new IA book for the Siege of Vraks with a new list for my Death Korps army.
I am currently saving up for the new book, but until I can afford it I am using my old ruleset (the most recent online update).
How does the new list differ from the latest update?
I assume it's streamlining it into the new Guard codex, have there been any drastic changes to the list?

I own the new Vraks book, but I have never used D.K.o.K. until this new book, so I am not acquainted with the old lists. I can take a look online for the info though and give you a comparison when I get the time.
