Google has announced the release of version 13·0·782·107 of its Chrome browser for all platforms (Mac OS X, Windows, Linux, and Chrome Frame). The new release incorporates a number of security fixes, listed in the release announcement, as well as some new features, including Instant Page rendering; this and other new features are described in a post at the Official Chrome Blog.
Because of the security content, I recommend that you upgrade to the new release as soon as you conveniently can. Windows users should get the new version via the built-in automatic update mechanism; you can verify that your system has been updated by clicking on the tools menu (the little wrench), and then on “About Google Chrome”. Linux users can get the updated package using their distros’ usual update tools.
