Google has added some useful new features in the beta version of the upcoming Chrome 48. One of the features exclusive to the Android version is Present to Cast, which takes advantage of the Presentation API and Cast SDK to allow mobile sites to present to Google Cast devices, which can then be controlled through the browser on the phone. So if the mobile site has some sort of presentation facility, you can cast it to a screen and use the phone as a remote to go through the presentation. The other addition is custom buttons in notifications. Chrome added custom notifications from websites since version 42 but now sites can also add custom buttons within those notifications for added functionality. The other main feature is that websites can now detect your maximum bandwidth using NetworkInformation.downlinkMax and NetworkInformation.onChange APIs to detect and change the download speed, respectively. They can then serve content accordingly. For other changes, check out the link...
