Syndication Links for WordPress 4.2.4 is out. It tries for a few fixes to the scheduling of syndications, refreshes the icons, and introduces one new feature. A custom query. /?syndication=twitter.com or such. It tries to return all posts that have a matching syndication link and can be added to any archive page.
Doing IndieWebCamp West Hack Day, and added another Simple Location for WordPress trick. I was doing custom rewrite improvements for Post Kinds, and added the ability to generate map views from any taxonomy or user.  Just add /map to the archive URL.
