I too am wondering that. I checked out the HG repository but it says version 0.9.5 and hasn't been updated since January. So I don't know if thats safe to use or what since this thread says v0.9.9. An the version on the teamspeak site is 0.9b.
EDIT: Nvm, re-read the above posts an saw the post about 0.9.9 coming soon an real life issues. So no worries,

I can totally relate to that as a lot of my projects keep getting delayed for RL issues, heh.
