I\'m using rvm (Ruby Version Manager) and running Rails 3 RC. I need to test an app to see if a bug has been resolved with a recent commit to Rails 3 master on GitHub.
Why not take a look through the commit log here: http://github.com/rails/rails/commits/master before cloning the repository? I don't know what bug you are looking for but remember, you can also look at the "diffs" from each commit to see what has changed.
