I warn you now, asking about the errata is a sure fire way to open a can of nuclear worms around here.
Basically, Major, the answer to your question is, simply, Both.
See, the SR4 faq was written over four years ago and posted to the main website. And it lingered there for quite a while.
Then along came anniversary edition, our new shiny savior of updated rules. And nobody changed the faq.
Then about a year ago, someone got the bright idea to answer some MORE faqs, and actually do some good customer service, and post it on the website for everyone to see. The thing is they didn't datestamp the new questions, or remove outdated answers to questions in which the rules had changed between editions. (mystic adept power splitting is a PERFECT example of this).
So the answer is both. A majority of the rules and clarifications are actually for 4th edition, but are still relevant because the rules haven't changed, or they handle general 'how does blank work' situations.
And then wormed in between the cracks are a handful of legacy/grandfathered in rulings which directly contradict the (new) main rulebook.
I also noticed that there was a bit of a stealth edit at one point, possibly during the update:
Q)Can complex forms be crashed, just like any other program?
A)No. Complex Forms cannot be targeted by effects that only affect programs (p.239, SR4A). This is a change from what is presented on p.136 of Unwired.
^ the faq originally supported the unwired ruling.
If you have a question about a SPECIFIC faq, then we can probably help you out a bit more directly.
By the by, I'm fairly sure I saved a copy of the original FAQ, if anyone wants to compare and contrast to the current one, and which were added.
