Google has released a new stable version, 17·0·963·83, of its Chrome browser for all platforms: Windows, Linux, Mac OS X, and Chrome Frame. This release fixes eight identified security vulnerabilities, six of which Google rates as High severity. It also fixes some bugs with Flash-based games. More details on these changes are available in the Release Announcement.
Because of its security content, I do recommend that you check that your system is updated. Windows and Mac users should get the new version via the built-in update mechanism. Linux users should get the updated package from their distributions’ repositories, using their standard package maintenance tools. You can verify that your system has been updated by clicking on the tools menu (the little wrench), and then on “About Google Chrome”.
