The confusion seems to be a result of this comment by Adoriele:
There's an addon named SquawkHard which pretty much does exactly what I'd envisioned for SAA2.0. What this means is that I've pretty much stopped development on SAA at this point. It does most of what I'd envisioned pre-2.0, and I'm more than willing to let someone else take care of the 2.0 features I'd planned on. I may still add some trinket proc checking, but that'd be about it.However, Adoriele clarified his comment yesterday.
I do intend to keep maintaining SAA. Heck, I still use it myself and any time it doesn't work properly I fumble pretty horribly. I just meant that SH does what I'd been planning to do with a future version, and unfortunately now that it exists I can't justify the time expenditure to reproduce it natively. I use both, though SH is really just a double-check in some of the timing-critical areas (less than 4s left on the cooldown, but is there enough time for another SF?).
So the basic translation is that if you like Squawk and Awe in its current form then it shouldn't be going anywhere anytime soon. If your looking for some added functionality to suggest spells or to see if you have time for one more Starfire you may want to give SquawkHard a try. I have not used it but Adoriele seems to think that it works well with his addon.
