+* new: `Response` constructor gained a 4th argument
+
+* deprecated: properties `Response::hdrs`, `Response::_cookies`, `Response::raw_data`. Use `Response::httpResponse()` instead.
+ That method returns an array which also holds the http response's status code - useful in case of http errors.
+
+* deprecated: method `Request::createPayload`. Use `Request::serialize` instead
+
+* deprecated: property `Request::httpResponse`
+
+* improved: `Http::parseResponseHeaders` now throws a more specific exception in case of http errors
