Read about the changes in 4.0. The list of revisions covers the differences between releases in detail.
Earlier releases have been removed because we can only support the current versions of the software. To update old code, read the changes page. Changes for each release can be found in revisions.txt. If you have problems with the current release, please file a bug so that we can fix it. Older releases can also be built from the source. Read More about the releases and their numbering. To use Android Mode, Processing 3 or later is required.
The changes document covers incremental updates between 4.x releases, and is especially important to read for pre-releases.
