Semantic Versioning

Details: http://semver.org/, http://apr.apache.org/versioning.html

Versions are denoted using a standard triplet of integers: MAJOR.MINOR.PATCH. The basic intent is that MAJOR versions are incompatible, large-scale upgrades of the API. MINOR versions retain source and binary compatibility with older minor versions, and changes in the PATCH level are perfectly compatible, forwards and backwards.

Patch level changes could also be for correcting incorrect APIs. In this case, the previous patch release may be incompatible, but because of bugs.

Minor versions may introduce new features, but do not alter any of the previous API.
