This one is just a small release, overall, with some key bugfixes to the last version. That said, however, there is a new implementation of the context menu, which we know a lot of people have been waiting for -- so yay! There's also a couple of smaller balance tweaks in there.
This is a standard update that you can download through the
in-game updater itself, if you already have 3.701 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
3.701 or later, you can download that here.
