A new software update is currently rolling out to some Amazon Fire TV devices. The update carries the same 188.8.131.52 version number as the previous software version, but the build number has increased from 587444320 to 587444820. I’ve only heard of the 1st-gen Fire TV box receiving this update, but I do not know if other devices will also receive it.
When a new software update rolls out with a new build number but the same version number, it usually indicates that the previous software version introduced a new bug that the new update is fixing. Since Amazon tends to not divulge which bugs are fixed, it’s difficult to know what changes this latest software update makes. If your device receives this update and you notice any changes or fixes, let us all know in the comments below.
