With growing evidence that Google will launch the Chromecast Ultra in Australia sometime in the next week or two, we’re seeing an update today to Google’s Cast API which enables the key feature of the Chromecast Ultra: 4K casting.

There’s another cool feature too, which means — put simply — that whenever a user is casting, other devices on the same network will get a notification which will allow them to control playback, too.

Like most people they will try and clear the notification – the x seeming like the logical thing to click (even though they swipe… Read more »
