Current state of game vs. V1.0

I haven't played the game for almost a year now and wanted to start a new save over my Christmas vacation next month. However, I just saw that V 1.0 will be released in mid-January, and I was wondering whether it makes sense to wait for it. What would those who know the current state of the game say - is it worth waiting a few more weeks at the end of December or are there only minimal improvements to come? I've read the roadmap post, but I'm not quite sure if I understand it correctly, which features are already implemented and which will be implemented in mid-January.
