/**
* SOF ABI versioning is based on Semantic Versioning where we have a given
* MAJOR.MINOR.PATCH version number. See https://semver.org/
*
* Rules for incrementing or changing version :-
*
* 1) Increment MAJOR version if you make incompatible API changes. MINOR and
* PATCH should be reset to 0.
*
* 2) Increment MINOR version if you add backwards compatible features or
* changes. PATCH should be reset to 0.
*
* 3) Increment PATCH version if you add backwards compatible bug fixes.
