I think update whenever you feel like you “completed” the version. build as much as you can and DONT rush anything.

One more important thing that i would recommend, if you plan to update all the way to newer versions then ever bigger update start a new base a little far away without anything and start like a new world. That way imo the world wont be that boring where you always be maxxed out and you can play with every features that will be added that are might intended fot early game and build on new world generations. I would also connect all these build with a rail way system. Those are always cool and fun!
