As SlashGear points out, the primary navigation elements have shifted from the left side to a bar across the top, with category labels. As far as individual apps, those can be reordered at will, while the FireTV and compatible apps are also accessible to more people with a VoiceView screen reader. This updated software is coming to the new stick and most recent Fire TV box first, later this year.

New Update Makes It Easier To Browse and Discover Content – Coming Soon

Coming later this year, a free software update for Fire TV will give customers a new on-screen experience that makes finding what to watch next even easier and more enjoyable. Fire TV will present a cinematic experience, offering video trailers and content screenshots to help customers access the content they want more quickly – without the need to open and close multiple apps. Finding and enjoying apps and games will be easier too with new support for a customizable apps list on the home screen. Accessibility improvements will also be included, allowing customers to use Fire TV and any compatible apps with the VoiceView screen reader. These features will be available for all Fire TV customers as a free, over-the-air update, starting with the new Fire TV Stick with Alexa Voice Remote and latest generation Fire TV later this year.

The all-new Fire TV Stick with Alexa Voice Remote is available for pre-order beginning today for $39.99 at www.amazon.com/fire-tv-stick and will start shipping to customers on October 20. Eligible customers who purchase online or from a participating retailer and activate their device by October 31 will also receive a free content bundle. This limited-time offer includes one month of Sling TV and two months of Hulu (Limited Commercials) for new subscribers, and a $10 credit for Amazon Video – a value of up to $65.
