Google has released a security fix to Chrome 23. The update will bring your Google Chrome browser's version to 23.0.1271.95. This update is minor, apparently, but it's a security fix so it's still important. Get the newest stable version of Chrome 23 by updating your browsers by clicking through Options > About Google Chrome > and wait for it to download and install the update. You can also download this update manually via the Google Chrome download page.
