2.0 Series — IPython 2.0.0 documentation. Very cool. This is slowly getting closer to the surface of Mathematica. Unfortunately, the strong focus on the browser - I can understand why, but I'm not really enthusiastic about it. I would prefer it to be a more integrated solution in the normal GUI. HTML as a rendering engine is fine, but the browser as a user interface is still quite clunky compared to an optimized native environment. But still, really cool what's happening here.
