Google has the release notes released for the Chromecast with Google TV. The update comes with improved 4k support for televisions and AV receivers, improvements for Dolby Atmos and Dolby Digital Plus, overall improvements around the recovery screen issue (which was sometimes shown as a bug), the December security patch and general improvements on in terms of safety, stability and performance. What it exactly means is not yet clear at this time. Users complained about the lack of, for example, Dolby Atmos at Disney + and there were also some problems with other streaming services. Hopefully that has been resolved with this update.
Last year we have the new Chromecast with Google TV tested. Positive points were the full smart TV platform and good support for 4k, HDR and audio standards. So, further improvements for video and audio are now being applied with this update. Many streaming apps are available, but not all of them yet. Thus the Apple TV app still on the schedule. Unfortunately it will not be added with this update.
Update available immediately
The update has been rolled out immediately and will be applied automatically. So you don’t have to do anything and you can expect the update of 78 MB in the coming days. Would you rather manually install the update? Press and hold the home button, choose system update from the settings menu and the new update should be available.
