8. Ruby 1.8.6
Mentor: Kirk Haines (at Engine Yard)
Since May 2009
“We will fix bugs and performance issues, address
security issues, and test to ensure that when releases
are made, they are of as high a quality as possible.
Anything else, like adding new API’s or behaviors is
completely outside of a maintainer’s role, so we won’t
be doing that.”
