Just a quick heads up that, as promised, the factory images for the Nexus 4, and Nexus 7 have been updated, should you need to get back to stock. Nice and easy. If you notice that there's no updated image for the Nexus 10, you've got a good eye. Google's JBQ in the Android Building Group notes that there was a problem with the JOP40C image (which has since been fixed). So hang tight. More on that here.
Otherwise, get your download on should you need to.
