The releases are versioned with MAJOR.MINOR.REVISION numbering, where MINOR is even (e.g. 1.12.0) for stable, and odd (e.g. 1.13.0) for development releases. The difference between stable and development releases is library interface stability. API/ABI compatibility between releases in the development branch is not guaranteed.
