The update is now available in the Google Play Store, just waiting for you to download it. Those who already have installed the updated browser are reporting that it seems faster, even when rendering image-heavy sites. If you already use the Chrome browser, you should see the update notification on your screen. If you don't use the browser yet, you can install it from the aforementioned Google Play Store. Note, though, that you need to be running Android 4.0 or higher to use the browser.
