Chrome 12 Accelerates 3D on Hardware, Boosts Security: "Hardware-accelerated 3D graphics and improved security are among the improvements as Google automatically updated Chrome on many PCs. Chrome 12 displays warnings about malicious web sites and controls tracking files."
Google Chrome 12 is now stable release : "Chrome now checks downloaded files for malware, and Google claims it has designed the feature in such a way that it doesn't have to know which URLs you visited or which files you downloaded to be able to detect malicious files. ... You can now also fine tune the data that websites store on your computer, including Flash Player's Local Shared Objects (also known as Flash cookies), directly from Chrome."
