| # Welcome to Processing 3

Read about what’s new in 3.0 →

Note that some sketches from Processing 2 may not be compatible. What has changed?

Since older sketches may not be compatible, we recommend creating a new sketchbook folder, so Processing 2 and 3 can happily coexist. This is a one-time process. Read more about it.

| Create a new sketchbook folder for use with Processing 3 sketches (recommended!)
| Use the existing sketchbook folder for both old and new sketches (may cause conflicts with installed libraries)
