A few hours ago, I posted a note about the release of version 28.0.1500.45 of Google’s Chrome for the Linux platform. Now the rest of the conventional PC world has been updated, too, with the Release Announcement for version 27.0.1453.116, for Windows, Mac OS X, and Chrome Frame.
This release incorporates fixes for a “click-jacking” vulnerability with the Flash plugin, and some other unspecified security issues. It also fixes some other user interface bugs; more detail is available in the Release Announcement. Although the identified security issue is not too serious (Google rates it as Medium severity), it’s probably a good idea to get the update, which you can do using the built-in update mechanism.
I confess that I am no more enlightened than before about why this update is different from the Linux update; I have no further information on what is actually in the Linux update.
