+### Breaking changes
+
+* Add `wrap-validation` middleware to validate Ring maps [#679](https://github.com/clj-commons/aleph/pull/679). While the Ring spec has always [required](https://github.com/ring-clojure/ring/blob/master/SPEC.md#request-method) a keyword value for `:request-method` (e.g. `:get`), previously, Aleph would also accept string methods (e.g. `"GET"`). This means that `wrap-validation` may cause HTTP requests to fail on previously valid input. This will be fixed in the release after 0.8.3.
