+### Allow * With Credentials Security Protection
+
+This library has been modified to avoid a well known security issue when configured with `AllowedOrigins` to `*` and `AllowCredentials` to `true`. Such setup used to make the library reflects the request `Origin` header value, working around a security protection embedded into the standard that makes clients to refuse such configuration. This behavior has been removed with [#55](https://github.com/rs/cors/issues/55) and [#57](https://github.com/rs/cors/issues/57).
+
+If you depend on this behavior and understand the implications, you can restore it using the `AllowOriginFunc` with `func(origin string) {return true}`.
+
+Please refer to [#55](https://github.com/rs/cors/issues/55) for more information about the security implications.
