Looks like Google is rebranding the logo for Google Chrome to look a little bit different in the latest development build. As you can see from the screenshot below which is from the latest development version, Chrome sports a new logo as compare to earlier versions.
The screenshot below is from an earlier version of Google Chrome
The newer logo is more flatter than the earlier one and does not have any spaces between the different colors and the ball in the middle. The grey delimiter has been replaced except for a circle around the blue ball.
I am not sure when this design change came through, but I would definitely prefer to see the older logo. What do you think? Which Chrome logo do you like among these two?
