Does the Chrome team think they need to reach version number parity with the other browsers? At least from a UI standpoint, the current version of Chrome that I'm using (5.0.375.99 Beta) is not enough different from the first Beta to warrant 4 full version numbers. About the only features that I can think of that are visibly new are the themes and the extension system. Did themes come with v4?<p>Also, if there are good reasons to warrant full version number change, then why are those versions installing automatically? A full version change is not an "update". It should be much more explicit to the user that a new full version is available.
