# Versioning
Releases follow the [semantic versioning](https://semver.org/) scheme with additional guarantees:
* Releases from 0.4.0 to 0.8.x are stable
* If 1.0.0 will introduce breaking changes then 0.8.x will be maintained as a separate stable branch
Currently 1.0.0 is planned to be [compatible](https://github.com/randy408/libspng/issues/3).
