Google has released a new stable-branch version, 23.0.1271.91, of its Chrome browser, for Linux, Windows, Mac OS X, and Chrome Frame. This version fixes a rendering bug on Windows Server 2003, and a problem with Flash audio. It also fixes six identified security vulnerabilities, two of which Google rates as High severity. 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.
