Owing to limited resources, it is the intention that future ruby-processing development will target ruby-2.2 (with likely compatibility with MRI ruby-2.1). Any remaining backward compatibility will be accidental. This change is obviously dependant on the release of jruby-184.108.40.206 (a recent fix to jruby-220.127.116.11-SNAPSHOT has been shown to work with the current version). But more significant changes will occur (for ruby-processing) as and when processing-3.0 gets released.

Now that jruby-18.104.22.168.pre1 has been released you can experiment with ruby-processing and ruby-2.2.0 syntax (works for me), if you want to run sketches that require jruby-complete checkout https://github.com/jashkenas/ruby-processing/tree/... (branch). All comments suggestions gratefully received (please post report issues/problems to github and not to stackoverflow!!!).
