 Status of downstream projects automatically built on top of the current htsjdk master branch. See [gatk-jenkins](https://gatk-jenkins.broadinstitute.org/view/HTSJDK%20Release%20Tests/) for detailed logs. Failure may indicate problems  in htsjdk, but may also be due to expected incompatibilities between versions, or unrelated failures in downstream projects.
