+- Support for Elasticsearch version `7.7`
+
+#### Custom Headers
+
+You can set custom HTTP headers on the client's initializer or pass them as a parameter to any API endpoint. [More info and code examples](https://github.com/elastic/elasticsearch-ruby/tree/7.x/elasticsearch-transport#custom-http-headers).

+- `delete_by_query`: Parameter `slices` can now be set to `auto`.
+- `reindex`: Parameter `slices` can now be set to `auto`.
+- `update_by_query`: Parameter `slices` can now be set to `auto`.
