+## 8.0.0
+
+First general availability release for `8.0.0`. Major versions of `8.x` will support Elasticsearch version `8.x` changing the `elasticsearch` dependency's major version: `gem 'elasticsearch', '~> 8'`.
+All references to `type` should have been removed. Document types were deprecated and do not exist in `8.x`.
+
+The dependency from `elasticsearch` on `elasticsearch-transport` was updated to `elastic-transport`. All `8.x` Elasticsearch APIs supported by `elasticsearch` should now be supported on the Rails library. See [Release notes for the Elasticsearch client 8.0](https://www.elastic.co/guide/en/elasticsearch/client/ruby-api/current/release_notes_80.html) and the [8.x release notes](https://www.elastic.co/guide/en/elasticsearch/client/ruby-api/current/release_notes.html#_8_x) for more information.
+
+### Compatibility
