New software updates have been rolling out to all Fire TV and Fire TV Stick models over the last few days. These seem like security and bug fixes, since only the build number has changed since the last update and not the version number. For whatever reason, the Fire TV 2’s software version has branched off from the rest of the Fire TV and Fire TV Stick devices. More so, the Fire TV Edition televisions also have their own software version, so there are now 3 different versions of Fire OS that are the latest, depending on which device you own.
Back in April, all Fire TV and Fire TV Stick models received an update to version 18.104.22.168 (Build 573210520). This was the update that brought the new interface to the Fire TV 1 and Fire TV Stick 1, but it was also deployed to the Fire TV 2 and Fire TV Stick 2. A few weeks later, a minor revision of this update was released to the Fire TV 1, Fire TV Stick 1, and Fire TV Stick 2. It carried the same 22.214.171.124 software version number but a new build number of 573210620.
Now, those same devices, the Fire TV 1, Fire TV Stick 1, and Fire TV Stick 2, have just started to receive a new software update. This new update again carries the same 126.96.36.199 version number but has a new build number of 573210720. It’s unclear what this, or the previous, software updates have changed.
Amazon has not updated the “New and Enhanced Features” list on their Fire TV Device Software Updates page. It still lists details of the first 188.8.131.52 update. This usually indicates the update contains no new features and just fixes bugs and security issues.
As for the Fire TV 2, it has not received these two newer versions of the 184.108.40.206 update. Instead, a 220.127.116.11 (Build 574262620) update rolled out about a month ago to just that device. Now, a slight revision of that update, with the same version number but a build number of 574263120, has started rolling out to the Fire TV 2. Again, Amazon has not listed any information for either of these last two updates for the Fire TV 2, so it’s unknown what changes they make.
Last but not least, the Fire TV Edition televisions have received an update to 18.104.22.168 (Build 577224220) . This appears to be the newest software version out of all the devices, so it’s the one most likely to contain noticeable changes that would eventually come to the stand-alone box and stick.
I have not had a chance to dig into these updates yet to see if there are any notable changes. One reader tells me this latest update fixed Dolby Digital audio over the optical port on his Fire TV 1, which broke with a previous update, so that’s one difference that appears to be present. As always, if you notice any changes, let everyone know in the comments below.
