Google has started rolling out an update of its Chrome browser for Android devices. The update brings Chrome to version 40, with the major change coming in the form of an updated page info and content settings UI.
Aside from that, Chrome 40 for Android (40.0.2214.89, to be more precise) has some bug fixes and improvements. In other words, this is not a huge update for the browser. As usual, your specific smartphone or tablet might not be able to download the update right away, but it should roll out for every user over the next few days.
You can grab Chrome 40 from the Google Play Store.
