A new software update started rolling out earlier this month to the 1st generation Fire TV Stick. The update maintains the previous version number of 220.127.116.11 but comes with a new build number of 587700820. No other devices have received this newsoftware version and it doesn’t seem like they will. It’s unusual for an update to roll out to a single older device and it’s unknown what this update changes. If I were to guess the purpose of the update, I’d say that it has something to do with optimizing video playback since the software update was released right around the time that the Silk Browser received a major update that focused on improving video playback on the 1st generation Fire TV Stick. If you’ve noticed any specific changes with this update, let everyone know in the comments.
