Version 0.3.1 of the SimpleCov code coverage analysis tool for Ruby 1.9, is now available.

SimpleCov uses Ruby 1.9's coverage library for gathering code coverage data, but also provides an API for filtering, grouping, merging, formatting and displaying those results. SimpleCov caches and then merges results whilst generating reports, in an effort to provide a more accurate report.

SimpleCov also comes bundled with a formatter for printing said coverage results.
