Today Google announced their progress and mission plan for taking care of the current and future security issues with their new Chrome browser. In particular, they revealed some details about the two biggest known flaws. Those have been fixed, along with some other minor issues.
Google also has opened a Chrome Releases blog, which they are using to openly document their progress on the browser. Unlike the often easily-readable release notes you normally expect from a browser like Firefox, Google wasn't all that revealing on what exactly it was they are doing with updates. With this, that seems to have changed.
The browser is facing criticism due to lack of site compatibility and other issues, but I think it is far too early after release to really judge what sort of browser it will be.
