After several months of work, a new alpha release of Processing 2.0 is finally out. This 2.0a5 release is significant because it includes many important changes (the detailed list is here), among them a completely overhauled OpenGL renderer. Since this renderer is brand new, not all the functionality is implemented yet (PDF recording for example) and probably contains several bugs that we will try to iron out in upcoming releases. I just wrote an entry in my blog describing the main aspects of this renderer.
