This one is another really long set of release notes, partly because it's been several working days since we've done an AI War release -- just due to timing, other obligations, the Tidalis updates, etc. But we've been working on AI War all throughout that time, too, which makes the list longer-ish, though not as huge as some of the recent ones.
This is a standard update that you can download through the
in-game updater itself, if you already have 4.000 or later. When you
launch the game, you'll see the notice of the update having been found
if you're connected to the Internet at the time. If you don't have 4.000 or later, you can download that here.
