I don't know if anything's actually changed here, but the issues discussing that and mentioning GPL are gone. Not "closed, fixed", but deleted instead. The author was claiming they delay the source release to prevent other projects from copying them, but argued with anyone raising the issue of that not being GPL compliant. It does not smell good.

The code currently says it's 0.10.4 (repo is for "community edition"), but the website changelog says 1.9.2.
