Starting from 2011 to 2014 there are different Chrome versions from 19 to the current 34.
One of the astonishing features about Chrome is the speed with which it updates its versions.
Chrome Beta now features a simpler, streamlined design; the menu bar is flatter, and the overall interface just feels more futuristic than Chrome does currently.
Chrome for Beta also features a dark theme for Incognito Mode—as if to imply that incognito browsing is a "secret" thing—as well as a new icon and a more simplified sign-in process.
Now you need to create a new user profile using this thread. Also as a major note, never access the About Google Chrome which you used to find the version number.
Otherwise it will again update to the newer version.
