 ## SDK versioning
 
 The goal of this package is to provide support for all released versions of CloudEvents, ideally while maintaining
 the same API. It will use semantic versioning with following rules:
-* MAJOR version increments when backwards incompatible changes is introduced.
-* MINOR version increments when backwards compatible feature is introduced INCLUDING support for new CloudEvents version.
-* PATCH version increments when a backwards compatible bug fix is introduced.
