Policy

We follow the semantic versioning policy (semver.org) with a caveat:

Given a version number MAJOR.MINOR.PATCH, increment the:

MAJOR version when you make incompatible API changes,
MINOR version when you add functionality in a backwards-compatible manner, and
PATCH version when you make backwards-compatible bug fixes.

caveat: Major version zero is a special case indicating development version that may make incompatible API changes without incrementing MAJOR version.
