Amazon has just updated their Fire TV Software Update page to now list the new 18.104.22.168 update that began rolling out last week. It appears as though the new update is only for the 2nd-gen Fire TV, since Amazon has only updated the listing for that one model. Amazon hasn’t changed the “New and Enhanced Features” section of the update page, so it’s still a mystery what this new update changes. Since the update is only being deployed to one model in the Fire TV lineup, it likely addresses a change or a fix related to that specific hardware. Amazon never gives any details about which bugs they’ve fixed, so we’ll likely never know what this new update does.
