Release 0.4

Release 0.4

We are happy to announce a new release first time at this site!

During last weeks a lot happened, number of test files generated multiplied several times, and while this is in large part different variants of calibration patches this is still a big step for the project. We support now pretty much every common format in widespread use today and ready to extend for new ones.
