Processing 4 is out!

Processing 4 introduces major improvements behind the scenes, with the primary goal to keep your code running smoothly on the latest hardware and operating systems.

If you are still using Processing 3 or a Processing 4 beta, we strongly encourage you to switch to Processing 4 to get the best performance, compatibility, and support in the future.


The core Processing software is augmented by libraries and tools contributed through the community. These inventive extensions are a bright future for the project. We have a list of Contributed Libraries and Contributed Tools posted online. These contributions can't be underestimated.

To contribute to Processing development, please visit Processing on GitHub to read instructions for downloading the code, building from the source, reporting and tracking bugs, creating libraries and tools.
