Hello :)
Issue saying "RN X.X.X version is out" are generally useless because I've subscribed to the Github release feed https://github.com/facebook/react-native/releases.atom, it is added in my favorite Feedly feeds and brought to my attention by the Feedly notifier Chrome extension. So I really can't miss a new release ;)
However I recognize I sometimes need to get my ass kicked, so please, post such an issue if the release is out for more than 2 or 3 days!
Of course, other kinds of issues, any thoughts, discussions, are warmly welcome!
