Google has released a new version, 9.0.597.107, of its Chrome Web browser, for all platforms (Mac OS X, Windows, and Linux). This update fixes 19 identified security vulnerabilities. More details are in the Release Announcement on the Chrome Releases blog. WIndows users can obtain the new version via the built-in update mechanism (Help / About Google Chrome). Linux users should be able to get the new version using standard package update tools (e.g., apt-get, synaptic).
Because of the security content of this update, I recommend that you install it as soon as you conveniently can.
