| 10 | * SOF ABI versioning is based on Semantic Versioning where we have a given
|
| 11 | * MAJOR.MINOR.PATCH version number. See https://semver.org/
|
| 12 | *
|
| 13 | * Rules for incrementing or changing version :-
|
| 14 | *
|
| 15 | * 1) Increment MAJOR version if you make incompatible API changes. MINOR and
|
| 16 | * PATCH should be reset to 0.
|
| 17 | *
|
| 18 | * 2) Increment MINOR version if you add backwards compatible features or
|
| 19 | * changes. PATCH should be reset to 0.
|
| 20 | *
|
| 21 | * 3) Increment PATCH version if you add backwards compatible bug fixes.
