[Technical]News Feed?

I'm currently developing a few apps for League, and I want to implement the current news into one of the pages. After looking through a few open-sourced projects, the general consensus seems to be that the news is located at http://ll.leagueoflegends.com/landingpage/data/na/en_US.js (note the .JSON format) , varying from region to region. However, this only contains old news. Was this news link updated, and if so, what is the new link?
