I have released a new version (revision 121), grab it here. I dub this the "AI release" as it mostly contains enhacements for the AI. Prior to this release it was still mostly at the same state as for the "Phase 1" release, so I added a lot of functionality to the enemy AI and also made it a bit smarter. The AI will now do most of the stuff that players can do in "Phase 2", including upgrading buildings, researching infinite technologies, doing espionage and sabotage and so on.

I also changed the construction AI (see this blog posting for more information), so the AI will now be much more competitive than before, populating regions in a better way than before that'll get upgraded over time. It also demolishes buildings that aren't needed aynmore, making space for better once. Also the AI is now less prone to loosing reagions due to high pollution or low loyalty.

Here is the complete changelog for this revision :
