* SOF ABI versioning is based on Semantic Versioning where we have a given

|
*
|
|
* 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.
