Expanded Tau Codex
 

So the expanded Tau codex has been up on GW for awhile now with some new units and such, is this currently being coded for AB? The website for the pdf (it is 1.4MB and thus cannot be uploaded here) is located: http://www.games-workshop.com/MEDIA_..._6th_Ed_V1.pdf

That PDF is the FAQ for the current codex - there are no new units, just amendments to make the codex with the 6th edition. What version files do you have loaded? The current version is 1.9 which was released on the 28th October.

Negative, many of the units have different abilities and some are completely new.

XV-33 Sniper team is new, two types of Fire Warriors now, Crisis weapons are different costs, stealth teams have new options, and several other changes. To answer your question, I have the 28 October one.

Where are you seeing these new units? There are none listed in the FAQ you linked to.

EDIT: A quick Google search of XV33 found a FANDEX which indeed had this unit, two types of Fire Warriors, and the other 'changes' you mention. I really hope you realise why this won't be included!

Pages 6-19, although if it is a fan things and not an official GW thing like I thought (since it was on their website) then I apologize profusely. Quite confusing since it was on their website and did not say unofficial anywhere.

Edit: Rechecked the link and it took me to a different place than what I had downloaded, this is the source of my confusion. I will search again for what I have, not sure of how I got it if it was not from the GW website.
