I've released pacman 2.0 beta to a select few Arch Linux users. I'm running it on all my workstations and it's smooth so far. A week or two of testing and it will be ready for release, though the new dependency logic isn't much use without a good dependency tree in the package set. *sigh* in time. The other AL developers are all busy with their real lives, so it's just me again, for now.
I'm hoping to get a 0.3 release out in the next 2-3 weeks. Then the plan is to release a pacman 2.1 which will have all the nifty features I didn't have time to get in 2.0.
