[[breaking_70_restclient_changes]] === High-level REST client changes ==== API methods accepting `Header` argument have been removed All API methods accepting headers as a `Header` varargs argument, deprecated since 6.4, have been removed in favour of the newly introduced methods that accept instead a `RequestOptions` argument. In case you are not specifying any header, e.g. `client.index(indexRequest)` becomes `client.index(indexRequest, RequestOptions.DEFAULT)`. In case you are specifying headers e.g. `client.index(indexRequest, new Header("name" "value"))` becomes `client.index(indexRequest, RequestOptions.DEFAULT.toBuilder().addHeader("name", "value").build());`
