Cruisecontrolrb users - Jan 2011 - Updating my CC.rb instance?

Hi,

According to https://github.com/thoughtworks/cruisecontrol.rb#readme
the last release was 1.5 years ago: v1.4 on 2009-06-30.  What version
of Ruby and Rails should I use with that release?

Should I instead just pull something from github?  If so, what version
of Ruby and Rails do you advise?

Thanks,

P.S. I''m currently using some hacked up v1.3 version I forked off
github
a long while ago.
