Google has released a new version, 8.0.552.237, of its Chrome Web browser for all platforms (Windows, Mac OS X, and Linux). The new release fixes 16 distinct security vulnerabilities. Further details are in the release announcement on the Google Chrome Releases blog. The Chrome OS release has also been updated, to version 8.0.552.334.
Because of the security content of this release, I recommend that you update your systems to the new version as soon as you conveniently can, You can use the built-in update mechanism (Help / About Google Chrome) on Windows machines; Linux users should be able to get the new version using standard package update tools (e.g., apt-get, synaptic). Alternatively, you can download installation packages here.
