The 1st-generation Amazon Fire TV and Fire TV Stick are starting to receive a new software updated, carrying version number 18.104.22.168 and build number 562254320. I’ve received the update and, unfortunately, this update does not bring the new user interface to 1st-gen devices. The new interface is still coming to older devices, but that will happen at a later unknown date. The update with the new interface will likely carry a version number of 22.214.171.124 or greater. I’m told this 126.96.36.199 update’s purpose is to patch various security vulnerabilities within Android. Assuming there aren’t any issues with the update, most devices should receive it by the end of the week. I haven’t noticed any new features or obvious changes with this new software version, but I’ll be doing my usual digging shortly.
