In addition to the fixes and features added in sprint 15 (watch demo video, ruby 2.0 adds significant performance improvements, new features, and is actively maintained. I highlighted many of the ruby 2.0 changes in my design summit presentation.
We are excited to continue to upgrade our ruby and rails stack and would like any feedback you have regarding these new appliances.
Thanks! Joe Rafaniello
