 # Change Log
 
+## 3.0.4
+Handle response.headers being None. (Fixes issue #217)
+
 ## 3.0.3
 Ensure that an Origin of '*' is never sent if supports_credentials is True (fixes Issue #202)
 * If `always_send=True`, and `'*'` is in the allowed origins, and a request is made without an Origin header, no `Access-Control-Allow-Origins` header will now be returned. This is breaking if you depended on it, but was a bug as it goes against the spec.
