Seems to be another great patch as far as I can see.
By the way, was the "paint select" feature only added recently? I've never stumbled across this before.
As for the tutorial, while it contains a lot of information, even I as a Star Ruler veteran find it far too much text too read. New players will be overwhelmed by the amount of information it contains; especially since it is presented in a rather minimalistic and passive manner ("Here, go read this 500-page book. You can play the game later."
I know this would take a lot of time and work, so I don't expect this to be realized anytime soon (if ever), but for a game of Star Ruler's complexity, the best way to get players to actually play through and understand the tutorial as a whole would probably be to divide the tutorial into several interactive chapters that are started separately. Despite the wealth of information, I doubt that I would've learned much from the tutorial if I was new to Star Ruler. Despite having read through it, I would have simply forgot about most of it after finishing it.
That said, it is still obvious you put quite a lot of work and effort into the new tutorial; so I'm not trying to bash you for it, merely suggesting what I think would be the optimal solution under ideal circumstances.
Regarding the new corona effect: Very nice! IMHO it could even be a littler larger by default - it should make stars look even more active
