I just installed 10.9.1 and so far so good. I had lots of problems and all didn't manifest right away, but no new issues yet.
The status bar is now correct on all monitors. I have one DVI and one HDMI connected to a dynadock u3.0.
The latest "beta" from Apple is 13B35. Apparently lots of devs have had problems downloading using the apple tools, so one of the devs posted a direct link - it is on an apple server and downloads fine in Chrome.
Check out the apple developer forums (login required) and search for 13B35.
