Nobody died, thankfully.
I finished bug testing and I could've made the update tonight, but it was getting late, and since these things never go as planned, I probably would've been up until 4 in the morning troubleshooting :)
Tomorrow night should be the night. Don't expect major changes, though. This update is more about the admin functionality that will let us update the categories and reorganize things. While you will see some layout, navigation, and functionality changes, it won't be anything earth-shattering.
