Dev team at Killerfish games considers us GOG users too much of a bother to keep updating the game in a timely manner. The latest update was released for the Steam version of the game 3 weeks ago from the day of writing this, and the patch has still not been released on GOG. This is the devteam's official response for GOG patch ETA: "We still have a final beta going on for this latest version over on Steam. Once that is released we'll push it out to GOG. Sorry for the inconvenience, but the upload process to GOG is manual and takes a lot of time, hence we're unable to keep it as frequently updated as the Steam version." So there you have it - they're skipping GOG patches with significant content updates (latest patch added more player submarines and USN ships, quick mission editor, etc.). They'll get around to us when they find the time.
