Ola Bini has been inducted into JRuby as a core developer during this development cycle.
He has been coding like an unstoppable machine and we want to make sure he gets the
recognition he deserves.

worth mentioning: Ryan Bell, Dave Brosius, Miguel Covarrubias, Antti Karanta, and
Michael Studman.

Additional thanks to all the people on our mailing lists who help give feedback and ideas.
