Just updated to 10.9.1 on my Mac. All seems as before for me but please note that I have finally disabled "Displays have separate Spaces" in Mission Control.
I just can't work with the new multiple screen behaviour. I think Ars Technica have just scratched the surface of why it's so inconvenient!

We're testing the released 10.9.1 formally as well, so far found corruption on the menubar and new use cases for the known Window Server crashes.
Can you please post here any new issues? We don't always need the full logs, the important details are usually the model of Mac, kind of connection (HDMI/DP/DVI/VGA) and if changing layout makes a difference, for example mirror/main screen or rotation.
Thank you
Carlo
