It isn't really an update. I'm still using it; it's doing surprisingly well. After 5.4's possible changes I may need to tweak the number of Arcane Shots in it, but until then, it's still:
/castsequence Chimera Shot, Steady Shot, Steady Shot, Arcane Shot, Arcane Shot, Arcane Shot, Steady Shot, Steady Shot
I still do Murder of Crows, Glaives, That Wolf Icon That Regens Focus, Rapid Fire, Readiness, and Army of Sporebats manually when they come off cooldown. As a Marksman hunter, I'm still average on AOE packs, but I'm generally competitive against similarly geared folks for single target DPS.
Other things recently... I've been trying to get my shaman up to the point she can be an alternate healer for our raids on nights we can't find one, and I'm liking shaman healing better than I did back when I last tried it: a.k.a., the Burning Crusade. I still prefer my priest, but we have plenty of priests available usually. I also like my baby druid healing more right now than I do shaman healing, but she's in her 40s, so that's going to take longer to do.
We're into Throne of Thunder! Currently on Tortos. My husband has done an amazing job both at finding us recruits, as well as finding us some casually allied guilds and friends who fill in when we're short two healers. Perhaps somewhat ironically, the only thing we're missing post-exodus is a full complement of healers, and that's exactly who left us for a bigger server environment. 5.4 and Connected Realms can't come soon enough.
