I noticed that the new binary for the 0.3.21 build Mac client was released the other day. So far it's running great for me, much faster than the previous release, but one question:
Does the 0.3.21 Mac client support the new automatic UPnP port mapping feature? I see the option in 'Preferences' but it is greyed out.
This is one new feature I was looking forward to, as I am behind a NAT and use Bitcoin on several different machines.
Many thanks to all the developers who didn't forget about us Apple-heads.
