The MetaCPAN site has a constant flow of new features. Some are small, some are big, but almost none of them get in the news. The recently added news page will provide this missing piece. It also comes with a feed.
One of the biggest advantages of MetaCPAN is that it is open source. There is a page for how to contribute to MetaCPAN, you can also read the PerlMaven article on how the newsfeed was added to MetaCPAN, you can then consider contributing too.
