1.1.1 feedback?

I'm not able to update at the moment, but I was curious to hear about a few changes from people who've been playing with the update. I know the framerate has been smoothed out, but I've also heard claims of less fog, more frequent sunny days, and tweaked pop-in distance.

Mostly I'm curious if the fog claims are substantial, and if the decreased pop-in distance is noticeably detrimental. Are there any good comparisons on this? Any first-hand experience to share? Thanks.
