The 0.1.0 API is aimed to be the 1.0.0 API. From 1.0.0, JsonQt will follow the normal standards for API and ABI compatability between versions: - Anything built against a specific version should work with any later version with the same major version; for example, something built against 1.0.0 should work with 1.1.0. - New features that don't break backwards compatability will result in a bump of the minor version; this should mean that anything built against version a.b.c will work with any a.b.* version.
