The new design just launched for both the parent site and Meta. Congratulations!
If you see any styling or css bugs, please start a new post, and tag it with "design" and "bug" please. This way it'd be easier for me to track and fix.
Congrats again, and thank you for your design input and support!
edit: since this question gets asked quite often: here's how you manually refresh the new favicons if your browser caches the old one.
load these two in browser address bar, and do a hard refresh.
