there is a 1.99c Beta out currently on Impulse. It includes: the updated manual, all the campaigns, the new espionage engine, and map settings for extreme worlds and random events.
There was one item in particular I found interesting in the manual- the Courage ability description. Before it has always been listed as an under-the-hood advantage given to soldiers in a close land battle. The new TA manual lists it as a weapons bonus given to a ship in battle when facing a superior foe, with the bonus being determined by the strength of the enemy ship. Interesting to know, wonder if that's what it really is, cuz that's kinda cool if so.
