Google is releasing a major update to Chrome today that will make browsing the web seem faster and also add security protections. Chrome 17 pre-renders pages in the background when you type in the URL in the omnibox address bar, so the site will appear to come up almost instantaneously.Chrome also now scans download executables (e.g., ".exe" and ".msi" files) and warns you if it thinks the file is malicious.
For more information on the new release, you can check out the Google Chrome blog. Otherwise, just update to the latest version from within your Chrome browser and enjoy a speedier web experience.
