Just 11 days after releasing a fairly substantial update of its Chrome browser, Google has posted an update that brings a new PDF views, security patches, bug fixes, and a few not so welcome interface tweaks. I really like Chrome, but I’m just a bit annoyed at losing the navigation buttons, and the Mac version innovation still tends to lag behind the Windows version a bit.

This week, Google announced an official version of Google Chrome, a result of the Chromium project, at the Web 2.0 Summit in California. What that means is that outside of nightly developer builds, this version—build 4.0.223.8—is the first official release build of the software. While the Windows version has been official and crushing it for quite some time now, Google certainly took their time on the Mac side.
