Thanks to Cord Cutters News, we now have confirmation that the new 18.104.22.168 software update, that was spotted yesterday morning, does infact include the new user interface. A reader sent Cord Cutters News the above image, as well as a shot of the software version screen.
The update is rolling out to Fire TV 2s and Fire TV Stick 2s first, and will come to older devices later. I’ll post more details about this new update and interface as it comes in. Be sure to comment below about any notable changes you find once you receive the update.
