An update Thursday to the Google Chrome developer's build for Mac introduces more than just stability-fixes. Included in version 4.0.295.0 are the basic beginnings of a bookmark manager and a trackpad gesture that allows users to open the previous and next pages in a new tab using the CMD-three finger swipe. The cookie manager has also been included in this minor update, so those three combined equal some actual feature improvements in this update.
Two other fixes, in addition to the spate of stability improvements, include making the devtools window dockable and fixing stuck hover states on tab close buttons. The Windows and Linux versions of Chrome dev also updated to version 4.0.295.0, although with different changes. The full changelog can be read here.
