The 48th edition of the IFRA guidelines are now up on their website, and will be applicable to any new projects briefed after the 10th of September.
I am not sure how strictly IFRA intend to police this particular date. But in these days of Edward Snowden and Ashley Maddison I suppose it is quite possible they would be able to read your emails if they put their mind to it. But seriously, you should at least be bearing them in mind from now on and preferably aiming to work to them. I haven't yet plunged in, but will be doing so as soon as the need arises.
You can find the details here.
