Only a few of the pieces are available online (though the complete .pdf is only a click away...), but the freebies include an editors' note on liberalism's decline, a piece by Seth on liberals and racism, an excellent essay by Mike Beggs on Marxist economics, Richard Seymour on left-strategy to combat austerity, and a couple others worth reading. It's a bit "light," but Gavin Mueller's is a favorite of mine, as well.
Standouts not available online include an essay by Lars T. Lih.
The art's more stellar than usual too: http://jacobinmag.com/blog/?p=615
