The next-version branch should be pretty playable with A26, as long as you avoid having the han civ in your games. Actually, i'll just temporarily disable them until my next release so you can still choose random civs without han in the mix. They still need a grapejuice overhaul and they throw errors as is because of that- which is also the major reason why i haven't released it yet. I'm planning to make a release for A27 though.
The next version also has new features (and probably more by the time it will be released) like:
Enemy player info is hidden in the diplomacy panel.
Players will get a clickable notification (location) if they meet an undiscovered player (building), this will fill in some info at the diplomacy panel. Notification can be disabled at settings > game settings.
