Processing 1.5 released

A lot has changed in the nine months since 1.2.1 was released, the biggest being the introduction of "modes" for the editor, allowing you to switch between Android development or the classic desktop/web mode. More modes are coming in future releases.
Another significant change is a fix for applets that were stuttering or appearing to run very, very slowly in Firefox 4 and Chrome. That's the major reason that we're releasing this version in advance on 2.0 later this summer. ... For people who have been using OPENGL2 in the pre-releases, the library has been removed from 1.5, and will return in future pre-releases before eventually replacing the built-in OpenGL library for 2.0.
