But you may not have heard about an even more significant change that was merged into Ruby 2.0 in January: a new algorithm for garbage collection called “Bitmap Marking.” The developer behind this sophisticated and innovative change, Narihiro Nakamura , has been working on this since 2008 at least and also implemented the “Lazy Sweep” garbage collection algorithm already included in Ruby 1.9.3.
