- Improved documentation to address [#22530] Mock methods with multiple return values not possible?
- respond_with parameter matcher was not available in tests.
- Patch [#22630] Fix for a bug in running Rails tests with Ruby 1.8.7. Array#flatten was being called which in turn was checking whether each element responded to #to_ary. This check was using the two parameter version of #respond_to?, but Mock was only defining a one parameter version.
