Until the squad builders catch up with the newly revealed information, you'll need to use a JSON text string to load the new upgrades. I don't really know how that stuff works, but I was able to figure out the syntax (turns out it's logical - go figure).

Now that I've done that, you can load a squad of 5 rookies with the new goodies into Vassal right now! just click Spawn Squad and paste in the following text, Happy Hunting!

This thread is now about bleeding edge content of all types!

Here's the autoupdater at work for a list with the (still unplayable because the dial is empty, since its moves are still unknown) TIE Reaper. It still spawns with the correct graphic on the ship, well assembled ship base, etc.
