+### Added

+- [#8](https://github.com/zendframework/zend-expressive-authorization/pull/8) adds
+  support for http-interop/http-middleware 0.5.0 via a polyfill provided by the
+  package webimpress/http-middleware-compatibility. Essentially, this means you
+  can drop this package into an application targeting either the 0.4.1 or 0.5.0
+  versions of http-middleware, and it will "just work".
