+- Description: In KubeVela, X-Definitions provide the foundation for users to construct their applications. Currently we will automatically upgrade the definitions' version for our users, however, we still need the capability of explicit versioning in definitions. With this feature, our users can now manage the version easily for application upgrades and migrations.
