Unless something changes, I don't see the manual being updated anytime soon. Gerry left our group of three for personal reasons, and like Gil alluded to, he provided the vast majority of the updates.
Steve was going through personal stuff around that time too and I just don't have enough time myself any longer with 4 young kids running around and a wife.
I'm a Mac user, so if I started doing more of the updates I'm sure I'd drive Keith nuts with all of the Mac screen shots.

There have been efforts to revive the manual a couple times in the last two years, but none of those have resulted in anything.
Anyone interested in helping out should contact Steve Giron and he can give you access to the master documents that are found on a Google Drive.
