 This project uses semantic versioning. Furthermore, this project provides code that was generated from schemata. Any schema change that introduces a breaking change in the generated code is considered as breaking for the whole project. Additional information is provided below when this occurs (named `Breaking schema changes`). Most of these occur in experimental categories and are unlikely to affect your code. `Breaking API changes` will be avoided starting with version 1.0.0.
