Sorry for not announcing this sooner, we released the newest Twilight beta and then I had to leave on a business trip.  Beta 6A is the first GalCiv II: Twilight of the Arnor beta to have a significant update to the computer AI along with some new balancing in it.  We're in the home stretch.

Here is the official plan for the rest of the beta:

April 10: Beta 6B

April 23: Release

We're pretty much feature complete. The rest of the time will be spent integrating player feedback into balancing (which means more techs, planetary improvements, etc), more AI updates, and integrating a lot of the new content we've been holding back on.

You'll want to keep an eye on the journals area as that will be where we'll be talking about things we're adding as we add them.

The full change log can be found here.
