* Fixed an issue in the CurlFactory that caused setting the `stream=false` request option to throw an exception. See: https://github.com/guzzle/guzzle/issues/769 * TransactionIterator now calls rewind on the inner iterator. See: https://github.com/guzzle/guzzle/pull/765 * You can now set the `Content-Type` header to `multipart/form-data` when creating POST requests to force multipart bodies. See https://github.com/guzzle/guzzle/issues/768
