v1.2.0

• New DSL syntax for defining whether jobs should run in parallel or sequentially. You can now describe complex workflows with parallel and sequential steps, see #29
• It's now easier to make sure that a job gets the input that a previous job wrote, see #26
• Support for custom input formats
• Support for using Java classes for mappers, reducers and most of the other configurations that take a class
• JRuby 1.6.x is no longer supported

Besides new features the test setup has been overhauled to make it easier to add new tests and a way to run integration style tests without shelling out to Hadoop. The tests are also no longer dependent on RVM.

This release was possible only because of @grddev and @jowl, thank you for your contributions!
