I saw the upgrade and clicked the button around 0730 MDT - around 1130 MDT the files finished downloading and installed.
The only issue I had is with my wireless networking. I use WPA with an RT 2500 chipset, and had used RUtilT to configure it. After the upgrade, RUtilT didn't work. After some talking with the developers, they suggested installing network-manager and using wpasupplicant. That worked - I'm connected through that wireless connection as I type this!
I really like the new version. The fonts seem cleaner - it's easier for me to read.
