Google has just released new firmware versions for Chromecast. Our last mention of the streaming stick and service was back in December when we said the Apple TV app would be available on Chromecast with Google TV. That was a month after when we learned the standalone Chromecast with Google TV remote was made available on the Google Store. A series of software updates is ready for several Chromecast devices. Note that most of them are done in stages.
The Chromecast with Google TV will receive build number 200918.033 with December 5, 2020 security update. This particular release comes with a number of updates including general security and stability and performance improvements, improved 4K support for TVs and AVRs, and Dolby Audio enhancement for Dolby Atmos and Dolby Digital Plus passthrough content.
