"Pretend we care"
I actually asked about this on Quora. Got an interesting response: http://www.quora.com/Why-doesnt-Facebook-list-changes-for-their-iOS-app-updates
brilliant, thank you! But.. they totally add user facing features in these releases. For example, "On this day...". And I'm sure, numerous changes to their advertising features.
Ah man I hate those. It seems like they could a little more...
This is to remove older negative ratings i guess. its been there since messenger.
