1.03 is "current". It's hard to say that it's out of date because there is so little specific in it. Rather than "manual", the title should be "quick start guide". Six pages on ships and no mention of combat? or how to move them?!
And a few statements that are just wrong:
With enough constructors, you can eventually develop a starbase with full mining, researching, cultural and military capabilities.
Sorry, no. It don't work that way.
Still, the production of a manual is a lot bigger project than most people realize. Maybe the manual isn't the best place for this. A wiki would be much easier all around, but really should have official Stardock participation.
