We use semantic version for the core or engine.
For each module we have the following categorization:
experimental: non backward compatibility changes are possible or even removal between versions (even patch versions).
provisional: low impact non backward compatibility changes may occur between versions; but in general a change like that will happen only between major versions.
stable: non backward compatibility changes, if happen, they will between major versions.
deprecated: it will disappear in a future version.
