@copilot You weren't supposed to remove all the other info, you were just supposed to integrate the v2 features, add/update/remove info as needed, but do not remove everything entirely.

Fixed in acda332. I've restored all the original banner content ("What You Need to Know", "Need Help?", etc.) and added the "Version 2 Features" section at the top of the expanded content.
