Google has changed the top navigation where you manage your settings. Here is a picture of the new way it is handled:
As you can see, the "Settings" link drops down when you click on it and gives you the option to click on "search settings" or "Google account settings." This is a small change and you will only see the drop down when you are logged into Google, but it is a change indeed.
The first person I know who spotted this was Darrin Ward. Outside of that, I have not seen much discussion on it. In fact, this is the first time I am seeing this new navigation, myself. Maybe it has to do with the top navigation going missing recently?
