SemVer

Kefir follows Semantic Versioning. But it still before 1.0.0, and for now version number follows this rules:

• If major breaking changes introduced, then MINOR (middle) number is incremented
• If there are no breaking changes, or only minor, which probably won't affect anybody, then PATCH (last) number is incremented
