Book on Zentyal 4?

[Gary Schiltz]

I know you guys are working hard to get 4.0 released in a couple of weeks, but I was wondering when/if there will be a new version of the book "Zentyal for Network Administrators"?

Also wondering on this. Now you have just recently release Zentyal 4.1 and the book is still on 3.2 sp2...   I am interested in studying for the exam ZeCA exam. I have deployed only Zentyal 4.0 servers so will the exam be based on the book @ 3.2 sp2 or is there at least an updated 4.0 book coming? updated exam coming?

Please let me know as I do not want to purchase an outdated book to find in a month or two the new book and exam based on it will be 4.0.

any info appreciated.
