when's the release of the windows client ?
After enough meaningful improvements have been made to make it worthwhile for people to upgrade from the official client. At this point the changes made so far are mostly cosmetic, renaming lingering NovaCoin / NVC references that pocopoco should've cleaned up originally.
Once we get a release I'll update the YaCoin information thread with the updated client info, if it looks like the reception in this thread is good. I'll keep the link to the old one around as well for reference.
