 * **BREAKING**: require Clojure 1.11, drop support for Clojure 1.10
+* **BREAKING**: new syntax for `:request` and `:response` per-content-type coercions. See [coercion.md](doc/ring/coercion.md). [#627](https://github.com/metosin/reitit/issues/627)
+* **BREAKING**: replace the openapi `:content-types` keyword with separate `:openapi/request-content-types` and `:openapi/response-content-types`. See [openapi.md](doc/ring/openapi.md)
