+## 12.0.0 (2021-06-07)
+
+> **BREAKING CHANGE**
+>
+> Big release! `oas/tooling` has been promoted to being the primary function of this library, while the existing CLI work remains intact and continues to be accessible with `npx oas`.
+>
+> Additionally, all CLI commands that talked with https://openap.is for OpenAPI hosting have been decomissioned. If you need a place to host your OpenAPI or Swagger definition, might we suggest [ReadMe](https://readme.com)! 🙂
