Admittedly this was a bit rushed because GW is pumping codexes out so fast but here it is. When in doubt, it's probably like the index. The "changes" summary in particular is woefully incomplete, and I would like to add a few more stratagems too but here she is:

I probably tried to do too much with this, adding 3 new units (a "Painseer" option for out-of-Commorragh pirates and 2 variants on Mandrakes one with their own psychic discipline - so that's 2 psychic disciplines in the dex), and trying to put summaries of all the weapon options after each unit entry, etc.
The structure of the deck is basically the same as the Chaos Demons codex. If you do Drukhari soup you get access only to the Drukhari relics, stratagems, warlord traits, and the "Alliance Attributes". If you dedicate to either Kabal, Cult, or Coven you gain access to each subfaction's relics, stratagems, and warlord traits in addition to the Kabal signatures, Cult obsessions, and Coven creeds which are more powerful than the alliance of death attributes.
Admittedly, the power-level is sloppy but I tried to get the points right at least. To calculate Power level all one has to do is add up all possible options in points for a squad of a particular size bracket (including the base models) and divide by 20 rounding to the nearest 20. I didn't want to crunch out the math for each unit (especially units like the Archon, who easily has the most options of any unit in the game).
I hope you'll find that generally you have more options in terms of wargear, said wargear is deadlier, there are new options like access to psychic powers and psychic defense, and character options, there are the standard perks of traits and points adjustments, poison is both more logical and more playable now, stratagems reward successful generalship, and speedy things are generally speedier. This is in my opinion my finest work to date. Enjoy, and I'm happy to look over other fandexes as well. Happy hobbying!
