Quick heads-up to Vassal players:
I'm halting development of the module. Could be I resume work at a later date, but I can't guarantee it. Depends on how involved I'll be in Armada in the future I guess.
Unfortunately that means there will be no Armada 4.0.0. I've spent quite a few hours working on it, but it's not in a releasable state.
On the other hand 3.8.2 is a stable platform, with only a few known bugs and omissions.
I'm sure you will also figure out how to add new cards and such. It's not difficult. Some of the other stuff (like adding new ships) is more involved, but it's not impossible to figure out. You'll manage.
Good luck!
