Yup, works perfectly for me and I'm unofficial. Whoooo! Now time to see if these problems have been fixed up! Also that was surprisingly quick. It was literally a 1 minute download on a crappy connection. Wonder what it did.
Edit: One thing I can tell right off the bat is that there are a hell of a lot more ranked servers.
# Improved Stability: We made several changes to core systems to help our stability problems. While some of you may still experience some crashing, this build is *much* improved.
# Fixed Server/Client Release: Gamer servers now correctly release clients if they quit the game, unexpectedly disconnect, crash, etc. No more servers filling up with "ghost" clients.
# Push-to-Talk: Now players can activate the VOIP by pressing the L3 button. Press L3 to activate a voice chat channel, release L3 to deactivate voice channel. The graphics/HUD updates that I mentioned in a post the other day are not in this patch, just the PTT functionality.
