This latest upgrade of Chrome uses a lot more memory on my Win7. I run 5 tabs and I see 10 chrome.exe running processes. WTF and why?

EDIT: I take the above comment back. The chrome.exe processes match with the process running in the Chrome's Task Manager. I stand corrected.

However, I think there's something new about the latest upgrade. The interface looks heavy and different. This is the same upgrade which has removed the green colored SSL identifier in the URL bar.
