Google has released a new stable-branch version, 23.0.1271.95, of its Chrome browser, for Linux, Windows, Mac OS X, and Chrome Frame. Thixs release fixes two security vulnerabilities, both of which Goggle classifies as High risk. Further details are available in the Release Announcement.
Because of its security content, I recommend that you update your systems as soon as you conveniently can. Windows and Mac users can get the new version via the built-in update mechanism; Linux users should check their distribution’s repositories for the new version.
