Didn't we JUST have WP 3.6? WordPress is pushing 3.7 to land this month, and 3.8 in December. That means that the new version is 'feature light' in that there's really only ONE super major ZOMG burn down the house feature.
Don't panic. If you're on our OCI, this is really old-hat for you. For everyone else, it's only minor updates. That means 3.7 to 3.7.1, and NOT 3.7 to 3.8. This was done to make things more like Chrome, or Firefox, where you don't have to think about security updates.
We've been testing the heck out of this, and I'm really confident in the code right now.
As soon as there's more info, I'll be sharing it with you, including an OMGWTFBBQ post
