Thanks for the feedback. To address some points:

“I like the older header better. I was slimmer and less intrusive.”
The idea was to make a bolder statement with a new header. Notice that now it contains page title too so in total the height is almost identical as before. Plus it collapses to a thin navigation bar when you start scrolling.

Wrench icon is only for site admins :)

The banner in the middle of the header was there before the change too. It is only displayed to guests though and disappears when you sign in.
