+### Semantic Versioning
+
+This package follows semantic versioning to an extent. However, the Riot API
+itself changes often and does not follow semantic versioning, which makes things
+difficult. Out-of-date versions will slowly partially cease to work due to this.
+
+When the API changes, this may result in breaking changes in the `models` module,
+`endpoints` module, and some of the `consts` module.
+"Handle accessors" may be removed from `RiotApi` if the corresponding endpoint is
+removed from the Riot API.
+These changes will increment the **MINOR** version.
+
+Parts of Riven that do not depend on Riot API changes do follow semantic versioning.
