I just released version 0.8.0 of MetricFu. New in this release:

• Source Control Churn now supports Git (thanks to Erik St Martin)
• Flog Results are sorted by highest Flog Score
• Fix for a bunch of ‘already initialized constant’ warnings that metric_fu caused
• The flog reporter can now handle methods with digits in their name (thanks to Andy Gregorowicz)
• Internal Rake task now allows metric_fu to flog/churn itself

To use the Churn task to find files that change a lot with Git, put this in your Rakefile:

MetricFu::CHURN_OPTIONS = {:scm => :git}

MetricFu is a Ruby Gem that gives you a fist full of code metrics. Find out more at the home page.
