Quoting jacklv, reply 1It is TA 2.03. No other changes.
This wasn't Impulse updating itself. It did that, and then updated ToA 2.03. It must have changed something. I'd like to know what.
Correct. Perhaps I wasn't specific enough.
It was a minor update to fix the GalCiv installer for better Windows 7 compatibility.
So, it won't do anything to change your game, other than perhaps making the installation process a tad smoother the next time you need to install it.
