Which version of Votv do you recommend?

I played Voices of the Void a lot back in the older versions (0.6.3, if I remember correctly), but then I stopped and came back during the transition between 0.8 and 0.9. Now I’d like to play again, but 0.9 isn't for me (it feels like too much work). Which of the recent versions adds the most compared to 0.6 without turning into a part-time job like 0.9?
