We're promoting 2.0.172 from Beta to the Stable channel today. 

We've made a lot of changes to stuff you never see, such as a newer version of WebKit for rendering web pages, a new network stack, and improvements to speed up the V8 Javascript engine.

There are some new features like removing Most Visited sites from the New Tab page, form autofill, and full screen mode. 

We're also proud to announce that Google Chrome is now available in 50 languages. We added Bengali, Gujarati, Kannada, Malayalam, Marathi, Oriya (on Windows Vista only), Tamil, and Telugu in this release.
