The Processing programming language/environment goes 1.0. From the press release:
What is new in Processing 1.0?
The most important aspect of this release is its stability. However, we have added many new features during the last few months. They include a new optimized 2D graphics engine, better integration for working with vector files, and the ability to write tools to enhance the development environment.
Download the newest version here. (thx, dan)
Update: Ben Fry has the press release.
